I need to write a little site using ZOPE3 as i using ZOPE2. Really i've also write an application on ZOPE3 by ZMI (the same in ZOPE2). This application insert (by a form) values in a database written in MySQL. Typical use is composed by the following steps: 1- a Page Template containing a form; localhost:8080/Mercatino/iscrizione_form:

Iscrizione

Nome:
Cognome:
E-mail:
Telefono:
User:

2- Previous form call a new ZPT, iscrizione_html in localhost:8080/Mercatino/iscrizione_html.

This ZPT use the package sql expr (but i don't like presentation and logic in the same object...) for use a query. I use "sqlexpr" because i don't know how pass parameter to a ZSQL script (passing parameter to a ZSQL in ZOPE2 work perfectly, but in the damned ZOPE3 NO!!!). How i can pass parameters? 3- THE REAL PROBLEM IS: In ZOPE2, if i want to use a PYTHON code, i insert a Python(script) into a folder and i call the script by using a ZPT (tal:repeat for example). In ZOPE2, NO PROBLEM but..... In ZOPE3, I can't insert a Python script by the ZMI, but i need to write a package (__init__.py, python class, ZCML etc...). I need a lot of examples for: a: write a package for my using and not like examples on zope.org b: write the ZPT that call the package c: acquisition doesn't work like ZOPE2 Now I HOPE that i've been clear.

There will be support for this kind of TTW editing in cpsskins (cf Custom Portlet), but it will be purely limited to "simple" presentation logic. cf. http://www.z3lab.org/sections/front-page/design-features/custom-portlet the difference with the Zope2 model I think is that "web producers" are not going to be ZPT programmers, but more like "site composers" with the ability to do minimal TTW template editing such as shown in the animation. /JM --------------------------------- Yahoo!

Message-ID: <4368F089.7040502@weitershausen.de> The Five team is happy to announce the release of two Five beta versions today, Five 1.2b and 1.3b! What is Five ------------ Five is a Zope 2 product that allows you to integrate Zope 3 technologies into Zope 2, today. Among others, it allows you to use Zope 3 interfaces, ZCML-based configuration, adapters, browser pages (including skins, layers, and resources), automated add and edit forms based on schemas, object events, as well as Zope 3-style i18n message catalogs. We've tried to keep the Five experience as close to Zope 3 as possible, so this means that what you learn while using Five should also be applicable to Zope 3, and viceversa. More information about Five can be found on our website, http://codespeak.net/z3/five/. Five 1.2 -------- Five 1.2 is the last release line of Five to work with Zope 2.8 and its included Zope X3 3.0. It does not work on Zope 2.7 anymore (use Five 1.1 if you're bound to Zope 2.7) Compared to the 1.1 release a month ago, it introduces the following compelling list of new features: * Local site support Five now supports local sites in Zope 2. Sites are a concept known from Zope 3 and similar to CMF's sites (only that they can be nested). Thanks to Sidnei da Silva for the initial development back in March, Lennart Regebro and Philipp von Weitershausen for bringing it up to date for inclusion into Five 1.2. * Improved event support Five can now make standard Zope 2 containers (aka object managers) send Zope 3-style events for adding, moving, copying and deleting contained objects, instead of calling their manage_afterAdd, manage_beforeDelete, etc. methods. Thanks to Florent Guillaume for thinking through this non-trivial matter and implementing it. * Marker interfaces utility Five now includes a feature known from Zope X3 3.0's introspector, the ability to set marker interfaces on objects to influence their behaviour (such as view or adapter look-up). This also includes a browser page with a page template macro for doing so through-the-web. This feature is based on Sidnei da Silva's Plone-based product Flon. Thanks to him for the original implementation as well as Godefroid Chapelle, Whit Morriss and Yvo Schubbe for bringing it to Five 1.2. * Class registration through ZCML It is now possible to register Zope 2 classes through ZCML so that they show up in the ZMI as addable meta types. This basically obsolete's the boiler-plate ``initialize()`` function in products' ``__init__.py`` files, as well as equipping classes with a ``meta_type`` in the first place. Thanks to Yvo Schubbe for suggesting and implementing this great helper for cleaning out Zope 2 boiler plate code out of products. * New test runner Five 1.2 (and only 1.2) includes a forked copy of Zope 3.2's improved test runner which brings, among others, better doctest debugging and support for running tests on different levels and layers. Thanks to Tres Seaver for integrating this into Five 1.2. For more information please consult the CHANGES document: http://codespeak.net/z3/five/CHANGES.html Five 1.2b can be downloaded at http://codespeak.net/z3/five/release/Five-1.2b.tgz. Five 1.3 -------- Five 1.3 is a straight port of Five 1.2 to Zope 3.2 which will be included in this December's Zope 2.9 release. Five 1.3 itself will also be part of Zope 2.9. It does not introduce any new features compared to Five 1.2, however, some restructuring has been made: * Most of the event work has been folded into Zope 2. That means that Zope 2.9 will ship with event-enabled object managers out of the box! * Several legacy packages were removed from Five as they are now included in Zope 2, such as Zope 3-style interfaces for OFS et.al. as well as the new test runner We are not providing a downloadable tarball of Five 1.3b. Instead it has been integrated into Zope 2.9 with which it will ship. To try out Zope 2.9, you have to currently check out the Zope 2 trunk from the subversion repository. About the Zope 3 Base --------------------- Five is part of the *Zope 3 Base* project, which aims to offer an approachable area for developers of Zope 3 related software. More about the Zope 3 base and its projects can be found on the project website, http://codespeak.net/z3/.

Ok, then I will skip the chapter "Approval Workflow for Messages". I now realize that trying to implement "step13" from SVN was a mistake, resulting from my confusion about how the "step" directories correlate with the tutorials in the Zope 3 Developer's Guide. I made the mistake of focusing all my attention on just Chapter 13, and not looking ahead to see that Chapter 14 correlates to "step2" in SVN. I thought that the "steps" listed within Chapter 13 correlated with the "step" directories in SVN, and was puzzled when things seemed not to quite match up. Now, back to "step1" in the SVN...

Where do I find the actual namespace? Namespaces only have to be URIs. They do not have to represent URIs with some content.

In-Reply-To: References: Message-ID: <436A0C11.1060101@4js.com.au> Hi again, Thanks for the help so far. Using schemas I can do the following: class IBuddy(interface.Interface): """Provides access to basic buddy information""" fullname = TextLine(title=_("Name")) email = TextLine(title=_("Email Address"), required=False) phone = TextLine(title=_("Phone Contact"), required=False) @interface.invariant def buddyInvariants(ob): if ob.fullname.startswith("Z"): raise zope.interface.Invalid("Names cannot start with Z") if ob.email is None and ob.phone is None: raise zope.interface.Invalid("Email and Phone cannot both be None") and: class Buddy(persistent.Persistent): """Buddy Information""" zope.interface.implements(IBuddy) def __init__(self,fullname=None, email=None, phone=None): self.fullname = fullname self.email = email self.phone = phone IBuddy.validateInvariants(self) This will do the validation on add. But how do I get the schema to be validated on an update to it? One way I can see is to have update method with named parameters (which does the validation at the end of the method), but then (I think) I lose the ability to have a directive to generate the html form based on the schema for free. Any suggestions?

By this, I mean a current, exhaustive list of allowed Field types and their arguments. I suspect when I go to the API documentation and enter zope.schema I'm getting the values, with some translation. But since those entries are in terms of interfaces and not the actual names to use (e.g., IText, not Text), I'd like to know more about how they relate. The "Programming with Zope 3" Tutorial and Richter's Developer's Handbook both discuss and list various options, but they have several limitations: * they aren't current * they aren't exhaustive * they aren't in the online help system. I'm looking for something that meets those requirements. The online book, in the entry Interfaces and Schemas | Schema Fields, begins "This document highlights unusual and subtle aspects of various fields and field classes, and is not intended to be a general introduction to schema fields. Please see README.txt for a more general introduction." I suggest changing this two ways. First, the "Schema Fields" section should appear after "Schemas." Second, the reference should be changed from "README.txt" (which is non-unique and wasn't even present in my Debian distro) to "Schemas". "Schemas" appears to be the same as the README.txt that I eventually found in the source tree. As far as I can tell, no section of the Book in the online help has anything near a complete discussion of the allowed field types.

After a lot of fooling around with the GUI and looking at various docs, I conclude I have no idea what's going on. To complicate matters, there were some issue with my installation on Debian (using the package in testing) so that some of the products aren't available. I wonder if any of them are key to getting things going. Do I need to create something like a Zope 2 user folder? Are all users defined in the principals file on disk? I tried installing a Site Manager object. The Site Management screen shows a lot of entries (e.g., Authenticator Plugin) that say there are no entries available yet. I installed some objects that seemed related, gave them names, and tried to hook them up with this screen. The only thing that seems to have worked is the unique id tool. I'd appreciate some pointers.

It tells how to install zope, but not really how to setup the instance, especially through the interface. E.g., p. 92 says it assumes you have created principal.zcml, but I don't really see anything about what should go in it. Further, the security framework appears to have been overhauled since the book was written (probably not in a way that affects what's in the book). I've found statements about the different components of the security framework, a reference to a default security policy, and info about how to code security. There's even info on how to write new types of authenticators. What I haven't found is info on the format of the principals file (though what's there provides lots of clues), how or if different credentials and authentication methods can be set via the ZMI, whether I need to create a site management folder, what to do with the options on the site management tab, whether I need to create user folders... Somewhere, maybe the Zope3 Dev Handbook, I saw a statement that user names needed a period. I'm not sure if that's true, since it's not mentioned elsewhere and my admin user doesn't have a period in the name and I can login as admin.

Has anyone yet tried sqlos with database connections created as local utilities ? At one point sqlos tries to get the utility in connection.py Line 88. newconn = zapi.queryUtility(IZopeDatabaseAdapter, name, default=None, context=context) The context points to a sqlobject instance. The problem is that these instances seem to have no parent and thus will fail the lookup my local utility and will raise an 'NoneType' object is not callable error later in the code when trying to adapt. When you try the sqlos example everything is fine, since the database connection is defined in configure.zcml as a global utility. My current idea is to expose the enclosing folder as a context to query utility. But I don't know if setting references in sqlobject instances is such a great idea.

The equivalent line would be: zapi.getMultiAdapter((object, request), Interface, name=u'') I just recently ported my wcsite package (available on http://worldcookery.com/Downloads) to Zope 3.1. It has code very similar to this one and provides examples of how the deprecation warnings are correctly avoided in Zope 3.1+.

Message-ID: <20051111005524.21121.qmail@web26501.mail.ukl.yahoo.com> I have a content component called 'journey' which provides three attributes: journey_description, journey_date, and distance_travelled. These 'journey' objects live in a container called 'car'. A car has attributes like owner, registration etc. So far, Everything is fine. I thought I would try to use adapters to extend the functionality of a 'car' object so that in the zmi_views, I could have a 'totals' page, showing the sum of the distance_travelled attributes of all the car's journey objects. I created an interface for the adapter, IDistanceTotal which describes one method, getTotalDistance. I created and adapter class, CarTotalDistanceAdapter. I updated configure.zcml like this: I tested the correct operation of the adapter in accordance with: Zope 3 Developer's Handbook,p142 and also with Web Component Development with Zope 3, page 149. The adapter was recognized, the getTotalDistance method appeared as an attribute of the Car object and valid results appeared for the distance travelled. I then created a nice page template which contains this snippet:
where context is the Car object. Now, here is my problem: no matter what I do in the configure.zcml file, I cannot seem to get the context object to pick up the getTotalDistance method from the adapter. Depending on the security/permissions settings I either see: forbidden attribute or not found errors. I have tried studying the code of the zwiki product but to no avail. Am I right in thinking that my problems are related to the configure.zcml file? Any pointers gratefully received. I can get the ISized examples from the books to work ok. Thanks to all.

How does your request look like? Note that we use POST in the edit form, so things should be fine.

It does all those type of things. The tinyu bit longer answer is: Develop a view class that implements a method called "POST" and then register this method as a view for IHTTPRequest.

Why does that not help you? nextURL() is really the method you want to override in your custom add view class. I know why it seems difficult though. Here is the scoop. You probably have troubles getting to the created content object. The trick is to override the add() method as well, so that you can store the new content object's absolute URL: def add(self, content): located = self.context.add(content) self.absURL = zapi.absoluteURL(located, self.request) return located def nextURL(self): return self.absURL + '@@edit.html' Note that I did not test the code, but it should be correct.

This is not such a complex case as you think. If you register an adapter from ISharedHouse to IAccreditationScheme then it will be only available for this interface and not for IAccommodation in general. I would even write a specific IAccreditationScheme for every scheme you support; thus you do not even need named adapters.

Message-ID: <9819d58b0511120840s8d52679v180b83f74535f0f@mail.gmail.com> Hi All, I've managed to dip my toes rather deeply in Zope3 without ever approaching the skins/layers aspect of it. I'm finally in a position to do that, and most of the examples I find extend the Rotterdam skin, and simply override it's macros. Is this simply for convenience, as there is a lot of useful functionality provided by these macros? Or is there some grander reason for using the existing with simple customizations? The main thing I could think of was that by doing this, you will can generally ensure consistent macro naming across different sites, which I suppose is helpful. I'm a very minimalist guy as far as HTML goes, so my initial inclination is generally to start with with the simplest thing possible, and expand it when necessary. What are people's experiences with this (keeping in mind that I am likely misunderstanding some large part of the way skins and layers are supposed to work :) ?

Well, something that hasn't been released in the first place can't be dropped. The problem is that it just hasn't been maintained lately because other things were the priority. This might change in the future and anyone's welcome to contribute. The current code is mostly at zope.app.schemacontent.

Well, Zope 3 doesn't care that Apache has authenticated your user. It doesn't see that. If you want the Zope 3 security system to interact with Apache's, here's a suggestion (not sure if it'll actually work): - Have Apache forward the REMOTE_USER CGI env variable, e.g. by using the "E" flag at the end of rewrite rule: [P,L,E=REMOTE_USER:%{REMOTE_USER}] - Have a custom ICredentialsPlugin that's simply looks at this env variable in the request for the log-in credentials. To challenge the user for authentication, it would simply use the same authentication realm as set in the apache.conf, so that it gets picked up by Apache when the user provides the credentials. - Have a custom IAuthenticatorPlugin that uses the credential data of the former plug-in to create a principal object from it. It wouldn't really need to do any actual authentication because that had already been done by Apache. The only thing this plug-in needs to do is convert the credentials data into an actual principal object. Hope that helps.

I feel not comfortable to put the username in URL. User may be able to bypass the authentication and direct access zope with username in URL. And that's true, Apache can pass environment variable via mod_rewrite. What's a pity. Now the only solution I found is only working in Apache2 not 1.3. I can use mod_header. requestheader can add http header to request before mod_rewrite pass it to zope. I can put REMOTE_USER in http header and zope will be able to pick it up. User will still be able to bypass the check if they can use special web browser which can add http header. But at least with standard IE & Firefox, this method will be safe. But I'm still using Apache 1.3. Above solution can't apply. :( I'm giving up. Maybe just use some browser script to submit current username to CredentialsPlugin. This will be easy, just write my own version of loginform.pt, and that will work. But it's ugly.

OK, so by targeting the registration of the adapter I can make sure each adapter is not available for types of accommodation object that it would not apply to. I'm with you on that. My thoughts about named adapters were related to the 'other side of the coin', where I have more than one scheme (and hence adapter) that would apply to one type of accommodation (for example the schemes represented by IAccreditationScheme and IHouseCheck would both apply to ISharedHouses). I guess what I want is to have both IHouseCheck and IAccreditationScheme available for ISharedHouses *in general*, and to select either (or none) for a given *instance* of ISharedHouse. Are named adapters the way to go for this requirement, or am I not understanding some mechanism in Stephan's suggestion that makes this possible without invoking that level of complexity? Thanks for the guidance so far.

(This is when using complex widgets like the ObjectWidget.) Some background. I'm trying to implement a ImageField and a FileField so I can add fields for Image and File objects to my schema. After experimenting with the IObject field for a while I've done the following things (I've only done the Image part, but files should be a matter of cut&paste): - Created an ImageField class (I basically just copied the Object implementation) - I've created an ImageWidget class (derived from ObjectWidget) and registered it as a view for the ImageField. - I've also added a custom IImage interface and Image implementation, because I want to add fields to the IImage. (I'm guessing that I "should" use annotations, but it's not gone happen in a long while, this is consuming far too much of my time as it is.) This works quite well (after endless fight with Z3 too understand how the schema system works). One of the hardest problem has been how to get information about my Image object from the view. In the ObjectWidget view the context is the field, the field in it's turn as a context that is the content object. So what I've done so far is just to climb up the context tree to get to an object not defining a context (and that has been the content object I'm after, but this strategy doesn't work when adding a content object for instance, because there isn't a content object too be found.) So I'm looking for a good generic way to find the content object (or None if it doesn't exist). Regards, Johan PS. I've also noticed that to be able to make web requests to the image object I need to specify the __name__ attribute when setting up the the field (just so that you know). Fields normaly lack the Location interfaces so one needs to figure out the location manually. Also fields need special traversers to be traversable from the web, it's a consequence of the explicit nature of Z3 I guess.) -- Johan Carlsson Tel: + 46 8 31 24 94 Colliberty Mob: + 46 70 558 25 24 Torsgatan 72 Email: johanc@easypublisher.com SE-113 37 STOCKHOLM From johanc at easypublisher.com Mon Nov 14 08:43:33 2005 From: johanc at easypublisher.com (Johan Carlsson) Date: Mon Nov 14 08:43:31 2005 Subject: [Fwd: Re: [Zope3-Users] Getting the content object from a widget] Message-ID: <43789485.8070101@easypublisher.com> -------- Original Message -------- Subject: Re: [Zope3-Users] Getting the content object from a widget Date: Mon, 14 Nov 2005 14:14:02 +0100 From: Johan Carlsson To: Johan Carlsson References: <437878AC.9090703@easypublisher.com> Johan Carlsson wrote: Well, I extended the search loop to look like this: def _getParent(self): curr=self while hasattr(curr, 'context') and \ (IField.providedBy(curr) or \ IInputWidget.providedBy(curr)): curr=curr.context return curr Which means that it returnes the first non field non widget it finds. It kind of does the trick. One would have though I could just use: def _getParent(self): field=self.context content=field.context return content But there is situations where a widget has a widget as it's context. For instance the default ObjectWidget uses an ObjectWidgetView as it's view class and when ObjectWidget sets it up it supplies context=self (e.g. a widget as context). I don't know why it's designed this way, in my ImageWidget, which is based on ObjectWidget, I've cut out the ObjectWidgetView and does every thing in the first view class. I did need to change the page template to use view instead of context but othervice it works ok (so far). If anyones interested I can make the ImageField code available.

This folder contained my test objects ( the Car and Journey example from my previous post). The data was trivial and no loss to anyone. I'm still experimenting. Anyhow, I tried to rename the folder to something more descriptive, and Zope3 keeps coming up with the "There has been a system error" page, and on the terminal it say s NotFoundError, 'myfolder'. I have gone into the ZODB directly, and the root['Application'] item contains the folder and its contents, but with the new name 'MileageTracker'. Firstly, I was a bit surprised that ZopeX3-3.0.0 did this on a simple rename, although possibly it has something to do with the contents of 'myfolder' which where my own attempts at creating containers. But now I'm intrigued because somewhere inside my ZODB the system has remembered the old folder name even the root['Application'] mapping object only seems to know the object by its new name. I have tried renaming the object back to its original name, and committing the transaction, but that does not work, an incremented integer seems to be added to the name. As I said, I'm not bothered about the data itself, it is just that I would like to use Zope3 in a production environment and I'd like to know how to recover from this type of thing. I've tried debugging the source by putting in print statements and as best I can tell, the magic is somewhere around line 604 in zope.app.registration.registration.py where "Adapters" is the supplied name and a serviceregistration object is createed whose componentPath attributes is 'myfolder'. From where in the ZODB is it reading this value! Any help gratefully received, John ___________________________________________________________ Yahoo!

This request could simply present any username desired. Some ways to limit the exposure of the hole is to have zope listen on the loopback interface only. Then prevent all shell access on the system. The only remaining hole at this point is if someone can abuse some other network-accessible service and coerce it into making the request (or to open a back door). -D -- Bugs come in through open windows.

If I define a field in a schema like: groups = List(title=u'Groups', default=[], description=u'Groups of the contacts', value_type=TextLine(title=u"Group")) and in the class implementing this interface: groups = FieldProperty(icontact.IContact['groups']) The problem is how to define that groups is a PersistentList.

Hi, While digging a bit depper into my problem I found out, that implementing ILocation will not do the trick, since the mentioned exception is caused by a factory call, and a factory will never have a __parent__ or am I totally wrong here ? Anyway I have created a functional unit test to demonstrate the problem. In fact the unit test shows that sqlos will always lookup global utilities and never local utilities. Here is the test.

When I traverse to the object in question in another browser, I get prompted for login. But if I supply different credentials (ie, one of the users not Allowed explicit view privileges), I'll still see the page. Am I denying the right person here? Globally, the permission is set up as follows: {'permission': 'zope.View', 'role': 'zope.Anonymous', 'setting': PermissionSetting: Allow}, Should I Deny access to the zope.Anonymous role? To the Everybody group? To the Unauthenticated Group? Right now, I only deny the principal: def denyUnauthenticated(self): """ Explicitly deny the view permissions for unauthenticated users. """ anybody = zapi.getUtility(IUnauthenticatedPrincipal).id pmanager = IPrincipalPermissionManager(self.context) for permission in self._view_permissions: pmanager.denyPermissionToPrincipal(permission, anybody) This is in Zope 3.1.0 on Python 2.3.5 The point of this simple 'sharing' interface is to let our customer have a press folder that they can restrict access to by allowing only limited people in to it. We're trying to keep the user interface as simple as possible.

No I was infact quite worng, it is possible to change the ZMI, just that one has too do it though the Site Manager not the contents view. And it solves the problem too. Thanks a bunch!

Hm. A very quick look at the patch concerns me a bit. Am I right that, if you apply the patch, then requests that are currently raising a NotYet for you will instead silently fail, not cataloging what you requested? That seems undesirable to me. I'd prefer the exception. If I'm on the right track here, then the extentcatalog in the zc.catalog package in the sandbox probably is one of possibly many other better solutions than the patch. It postpones cataloging to the end of the transaction, which I believe will remove the NotYet exceptions *and* successfully catalog your data. Apologies if my quick patch read is off base.

In my case I'm not interested in cataloging anything, there reason is I'm just adding new fields to a newly created catalog and there aren't any object to catalog just yet. I'm guessing Ivo has similare problems because he also are creating the catalog programmetically. I'm doing this as a part of a custom add view that defines a overrided createAndAdd(self, data), I think Ivo does it in a more CMF like fashion (just after quick glans on his code). I don't have the faintest idea what NotYet is supposted to be raise for? Accutally I'm haveing problems finding the code that does this because the traceback is Zope 3 cryptic and I don't have a debugger setup either.

Our framework relies on that concept and it is still working ;) Did you assert to add the catalog to the sitemanagement folder before adding its indexes?

I found the error, in the AddView I had to remove the security context to be able to setup things, I don't need that in the event handler. The removed security context appears to have been the reason for the NotYet problems.

''If an add event is generated and the object can be adapted to IObjectAddedEvent, then the adapter's addNotify method is called with the event.'' This could be alternative way to implement the the subscriber solution above. However, from looking at the code (Zope3.1) it doesn't seem to to what the apidoc claims.

(Evolving an application for the first time) Message-ID: <88d0d31b0511181024g79258187u93ed29ff1448af40@mail.gmail.com> I have an application where I'm trying to use 'zope.app.generations' for the first time. And after much pulling of hair and looking at the core code, I found what may be a missed scenario. Basically, we deployed this application for a customer and now they want some changes. It changes the schema of one item to store values in tuples instead of strings. I wrote an evolve module, 'evolve1.py' in myapp.generations, made the schema manager, registered it as a utility, bla bla bla. But my code seemed like it would never run. I'd run the debuzope script and look at the database root['zope.app.generations'], and there was 'myapp' with the value of 1. I'd keep deleting that key and committing the transaction, but my code would still never run. I tried running it manually using pdb.run() to step through it and make sure that it was finding the right objects and doing its job. My code was fine. So I looked at the code in zope.app.generations.generations and found this interesting tidbit: for key, manager in findManagers(): generation = generations.get(key) if generation == manager.generation: continue if generation is None: # This is a new database, so no old data if IInstallableSchemaManager.providedBy(manager): try: manager.install(context) except: transaction.abort() logging.getLogger('zope.app.generations').exception( "Failed to install %s", key) raise generations[key] = manager.generation transaction.commit() continue (the code continues from there There's one problem here - in my situation, it's NOT A NEW DATABASE. There is old data that needs to be evolved, but there's no record of a generation for this application because there was no need for a schema manager until now. I really like the concept and general implementation of the schema manager, but this scenario is driving me crazy. I could write an 'install' script, but that doesn't really cover this situation. After install is run, the database marks the application generation. This makes sense for new applications installing themselves - there's no old data to update, so if the application is at generation 5, for example, it doesn't need to be evolved to '5' if all of the data that's installed or used is already in generation 5 form. (ie - if I were deploying my application fresh today, my fields would already be tuples instead of strings). But my situation, where I already have a deployed application, is not covered by this. I *could* write an 'install' script for the schema manager that did this first evolution that I need to do. But then that installer would have to be updated with all of the future evolutions as well - since in theory, I could update an application from before the schema manager and need to bring it up to generation 5 or 8 from essentially 0. It seems like the Schema Manager needs an 'evolve from 0' option, with '0' being set by the evolution script of no previous evolution was found but (somehow) existing data could be detected. The other solutions seem to be: * Write an install script that then manually calls all of the evolvers to bring things up to the current generation. * Always put a schema manager in your application, with the starting generation of 0, so that you can upgrade in the future. Neither option seems quite tenable - like a bad hack that goes against the Zope 3 concepts. You shouldn't need a schema manager utility until you need it, and having a script that manually does 'evolve1.evolve(context); evolve2.evolve(context)'... seems like it goes against the sort of problem that the generations system is trying to solve. Is there something about the schema manager/generations system that I missed?

Note that a common strategy for install scripts is to run evolution scripts. This is fairly straightforward. The assumption of the generations system was that you would use it from the start.

Only this: I don't want to saddle developers with supporting all old versions of their products. In many cases, this could represent a very significant burden. There are really 2 related cases: install and catchup. Install is meant for situations in which an application hasn't been used before, while catchup is for apps that need to get around not providing generation support in the past. Unfortunately, there's no way for the generation system to know which situation applies. Presumably, an install script can have the logic to know this and perform some appropriate action. Note too that an application that needs to catch up from an "unmanaged" generation to a current generation might prefer to provide a direct conversion, rather than taking intermediate steps. Assuming that the best way to catch up is by running all evolution scripts from (before) the beggining is guessing too much. In summary, I think that the installation script is the right way to handle this situation. Jim -- Jim Fulton mailto:jim@zope.com Python Powered!

I've also created a loginForm.html that looks like that:
If I try to call a page which reguired a specific permission the loginForm comes up. But when I enter the login and password of the Principal in the Principal Folder or a the manager principal defined on creation of the instance I just get redirected to the login page again. This now was the behavior before a played around with the PAU a bit now it has changed to a system error: TraversalError: (Principal(u'pre1'), 'getLogin') The error log information of the user: User: unauthenticated, pre1, CS.User, pre is the prefix of my principal folder (BTW: what is the sense of this prefix), 1 is the object id of my test principal, CS.User the role of the principal.

My opinion is that you will never be able to import your Zope 2 product as a packge in plain Zope 3. HAving said that, there are continuous efforts, such as Five and Goldegg, to bring Zope 3 technology into Zope 2.

Unfortunately the whole 'X' story was always interpreted differently by different people. It's unfortunate, and our (the Zope 3 project's) mistake, that your interpretation ("Zope 2 products work in Zope 3") ever was made possible in the first place... > The 'x' was removed > on grounds of being ready for production use, not on grounds of > compatibility.

As Stephan said in his reply, I find it unlikely that you'll ever be able to run Zope 2 products in Zope 3. We're taking the other direction -- Zope 2 products run in Zope 2 obviously, but we're making sure that with Five, more and more Zope 3 code also works in Zope 2. This allows you to start porting code over to Zope 3 while it remains to work in Zope 2. Five is hardly the perfect transition tool; most of Zope 3 code doesn't work in Zope 2 either without significant modifications. Step by step however this gap is being bridged.

Thanks Martijn, From a quick glans at your code the notisable difference is that I don't call zapi.getUtility(ICatalog, u'my_catalog') to get the catalog, that just might do the trick. (I jsut grab the catalog from the container: c['catalog']. I'll let you know when I get a chance to test it. Does you code for adding catalogs and adding fields get called in the same request? Mine does, it gets called right after each other, and I'm thinking in the lines of that there is something that doesn't get setup in the correct order, which is why I think getUtility might work better. > Anyway, once you do get the catalog working, you may want to check out > hurry.query, which makes querying the Zope 3 catalog a lot easier (in my > opinion): > > http://codespeak.net/svn/z3/hurry/trunk I'll check it out :-) Cheers, johan -- Johan Carlsson Tel: + 46 8 31 24 94 Colliberty Mob: + 46 70 558 25 24 Torsgatan 72 Email: johanc@easypublisher.com SE-113 37 STOCKHOLM From atrium601 at gmail.com Wed Nov 23 10:23:48 2005 From: atrium601 at gmail.com (Rui Gamito) Date: Wed Nov 23 10:23:58 2005 Subject: [Zope3-Users] Zope 3 and Plone?

I guess that you still have to grant permissions or a role to the principal. If you want to grant it globally you should login as admin and get to the rootfolder ("[top]"). There is a "Grant" item the ZMI menu.

When a similar issue came up for me, all I did was add an additional type field to the content object then created a "render" method in the view, something like this for a 'description' field: def renderdescription(self): # for rest, self.context.descriptiontype would be 'zope.source.rest' source = zapi.createObject(None,self.context.descriptiontype, self.context.description) textview = zapi.getView(source,'',self.request) html = view.render() return html And then just used "view/renderdescription" in my templates. On grepping the zope codebase quickly, it looks like the more "modern" way to do this would be to use getMultiAdapter like: source = zapi.createObject(type,text) renderer = zapi.getMultiAdapter((source, self.request)) return renderer.render() I have no idea why I have an extra 'None' argument in my code, above See zope/app/preference/browser.py for an example From mdudzikml at gmail.com Fri Nov 25 20:07:53 2005 From: mdudzikml at gmail.com (Michael Dudzik) Date: Fri Nov 25 20:07:58 2005 Subject: [Zope3-Users] reST for content editors In-Reply-To: <1132967084.21774.248351107@webmail.messagingengine.com> References: <1132967084.21774.248351107@webmail.messagingengine.com> Message-ID: <1132967273.21993.248352267@webmail.messagingengine.com> On Fri, 25 Nov 2005 19:04:44 -0600, "Michael Dudzik" said: > On Fri, 25 Nov 2005 17:15:24 -0600, "Brad Allen" > said: > > I'd prefer to allow content editors on my site to avoid having to > > type HTML, and have heard that reST might be a good, wiki-like > > choice.

The old thread not only didn't resolve it, it never (IIRC) even generated a likely theory for the waitpid() failures. BTW, you had another test (testRunIgnoresParentSignals) fail with "spawned process failed to start in a minute". For that one, look for file "donothing.sh" and make sure its execute bit is set. In some combinations of Zope + Python, the execute bit on donothing.sh is getting cleared, and then testRunIgnoresParentSignals spins its wheels for a minute wating for donothing.sh to (despite its name ) "do something". donothing.sh won't exist in the next Zope3 release.

I have ambitions for using Zope 3 in several different projects, and am actively working on a Zope 3 website that I hope to have looking presentable if not fully functional by mid-December. It will probably look a lot like a static site at first, with a few added features like messageboard functionality (I hope it will be ok for me to use MessageBoard from Stephan Richter's book for a non-profit site). Later we will want to add features for wiki, blogging, event calendar, and document library. Another Zope 3 project for the future is to convert an ecommerce site I had previously built in PHP. I've been using Python at my day job now for a couple of years, and have decided I no longer have time for PHP--I want to switch the site to Python, probably using Zope 3. This site's main purpose is to allow customers to search, view, and purchase from a catalog of auto parts. With these two different types of sites in mind, some design questions have come up in relation to Zope 3. For the auto parts site, I am thinking about designing an AutoPart content component. This will allow the business owner to edit his catalog of auto parts via the web. Suppose he starts instantiating a lot of auto parts, and editing them. Later, we decide we need to refactor the base class, and maybe create a few child classes. That leaves me with a big cleanup chore, because a lot of old AutoPart instances are sitting around in the database. What's the normal pattern for dealing with this kind of cleanup? Am I better off just using SQL tables to provide persistence, and not storing my object instances in ZODB? At least with SQL, it's easy enough to manipulate the content data, and just re-instantiate AutoPart objects from SQL when needed. I'm trying to come to an understanding of when it's best to keep data in the ZODB, and when it's best to use SQL instead. Maybe there are tools for handling ZODB data that I don't know about. Another question about ZODB is whether to use it to store page templates. If I build a lot of ZPT pages and macros and store them through the ZMI, and then later want to rearrange the folder structure, I'm guessing it will be a pain to change a lot of hard-coded path references. If I use text files outside the ZODB, then I can use a host of text editor tools for searching across multiple files. I like the idea of letting end users have something like the ZMI for editing content, and am hoping it will be possible avoid putting much TAL and METAL markup in documents in the ZMI, but rather have the .pt files pull content from the ZODB. However, it's not clear to me how to make that work. The examples in the books have the .pt files in the filesystem; I don't recall seeing any the ZMI/ZODB. Here is another question. Suppose I'm working with a team of developers. Should we each set up our own separate Zope3 instance, and do SVN checkouts into our own separate, local /lib/python directories inside the instance? How then would we merge any changes done in the ZODB? On the other hand, having all team members try to share a single Zope 3 instance seems unworkable... Thanks for any insights you can provide.

For instance, suppose we have a top level container which holds items of type one. There are also items of types two and three somehow connected to the top level container. To avoid having to filter item types all the time, we don't just want to mix them in among the type one items. However, we don't want to put folders in the top level container to hold all type two or type three items, resp., either. The reason being a feeling that such folders would not provide well-defined enough access: they might be renamed, or there might be more than one folder holding items of either type. Our current solution is to register utilities that handle type two and three items, and turn them into folders actually containing the items while we're at it. This does provide uniqueness of the type two and three item containers, as well as well-defined access by an interface name. However, I'm not at all sure that containing application data is what utilities are meant for. Is it? I get a feeling that we might want folders as attributes of the top-level container, for all the uniqueness and well-defined access that provides. But would that be Zope-3-ish? -- Thomas From brad at allendev.com Tue Nov 29 22:07:13 2005 From: brad at allendev.com (Brad Allen) Date: Tue Nov 29 22:07:18 2005 Subject: [Zope3-Users] need guidance In-Reply-To: <6A5A9B2E-1F2F-42D7-B56A-73E21BD41D0C@plope.com> References: <6A5A9B2E-1F2F-42D7-B56A-73E21BD41D0C@plope.com> Message-ID: Chris McDonough wrote: >>Here is another question.

Ok, so this kind of discussion makes me wonder how much I can do without ZODB, or at least whether I can just use the ZODB files like any other binary files in the SVN repository. Having to write scripts to regenerate them sounds like a lot of ass-ache. Is there any reason why I can't just check in those data.fs files into SVN along with my Python packages, so that other team members can check them out into their respective Zope instances?

It sounds like a pain, and to be honest, at first it is a bit arduous. Not only does it get faster and become second nature, but chunks of it can be generalized and reused. It really doesn't take that long to get accustomed to it. And once you start doing it regularly, you gain a tremendous amount. Not just in the mere knowledge acquired, either... there's a subtle shift in your programming where you give extra attention to the data-generating/-populating code, which in turn makes you architect your information better ahd brings higher overall levels of organization to your project. Additionally, the ability to generate a new instance of a project complete with a fresh-and-ready ZODB is of immense value when working on a project with multiple developers or teams of developers. Several times, we have saved literally days of work taking advantage of this. I'm sure others that take even better advantage of this have saved perhaps weeks.

Although there is at least one tool that helps with just this called GenericSetup for Zope 2. I suspect that tool could be made to work with Zope 3 with a bit of work. > Is there any reason why I can't just check in those data.fs files > into SVN along with my Python packages, so that other team members > can check them out into their respective Zope instances? No, as long as your code matches the pickles in the database binary stored in CVS. The problems start when you need to change the code in a way that makes the pickles in the database incompatible with the code; for example if you need to change the name of an instance attribute in one of your classes; the pickles have the values stored in the old attribute name and your new code expects the new attribute name. So the code fails on the old data. This is of course the same problem you have when you need to change the schema of a relational database and you have an existing database instance. That said, Zope 3 comes with a tool named "generations" that allows you to evolve database pickles in a uniform way by writing evolution scripts. - C From chrism at plope.com Tue Nov 29 23:12:48 2005 From: chrism at plope.com (Chris McDonough) Date: Tue Nov 29 23:12:50 2005 Subject: [Zope3-Users] need guidance In-Reply-To: <5f870c883c623793e47b7c4baa9e8f44@gmail.com> References: <6A5A9B2E-1F2F-42D7-B56A-73E21BD41D0C@plope.com> <5f870c883c623793e47b7c4baa9e8f44@gmail.com> Message-ID: <322B2C14-03AC-479C-A278-732CFD860806@plope.com> On Nov 29, 2005, at 10:29 PM, Duncan McGreggor wrote: > Additionally, the ability to generate a new instance of a project > complete with a fresh-and-ready ZODB is of immense value when > working on a project with multiple developers or teams of > developers.

You could also just check in a generated database into CVS and use that with some of the same benefit but FWIW, I find the biggest value in being able to review this kind of setup code is that it serves as a kind of documentation as to *how* an iinitial database got created. Also, setup code is often complex and subtle because it's "where the rubber meets the road" in a production configuration. Being able to replicate it on demand with subtle changes (like port numbers and filenames) is valuable when you want to roll out a system into production. - C From brad at allendev.com Wed Nov 30 00:57:05 2005 From: brad at allendev.com (Brad Allen) Date: Wed Nov 30 00:57:09 2005 Subject: [Zope3-Users] need guidance In-Reply-To: <5f870c883c623793e47b7c4baa9e8f44@gmail.com> References: <6A5A9B2E-1F2F-42D7-B56A-73E21BD41D0C@plope.com> <5f870c883c623793e47b7c4baa9e8f44@gmail.com> Message-ID: Duncan McGreggor >It sounds like a pain, and to be honest, at first it is a bit >arduous.

So this style of Zope 3 development involves not using ZODB so much for permanent storage, but instead as a temporary scaffolding on which to hang the current version of class instances and their content. When you refactor your classes and interfaces, you just re-instantiate everything into the ZODB to recreate the site. It sounds great, except not all data can be simply regenerated. For stuff like port numbers and configuration, fine, it can be in ZCML or embedded in Python scripts. But the site content generated by end users has to be stored somewhere, too,. If you throw away your ZODB and regenerate it, what happens to that data? Does your regeneration script transfer all that data to the newly generated ZODB? I'd be interested in seeing the particulars of how you guys do that stuff. I've yet to run across a direct mention of how to create an arbitrary ZODB and start reading and writing objects. That seems to be a big piece missing from my understanding of how to work with Zope 3. Every ZODB example I've seen in the books seems to involve creating a content object that can be added via the ZMI. However, I'm not finished with either book, and I have very likely missed something.

While you're developing, it's much easier because the *content* in your ZODB doesn't typically have any value during development. If it does have value during development, you have a development model that's not similar to mine. But obviously, after you go into production, the content does have value, and preserving this value is the purpose of GenericSetup for Zope 2. It's a "dump and reload" solution which allows you to create a represention of your ZODB data and its associated hierarchy as files on a filesystem. You can basically push a button to dump the data in your ZODB ro files, and then create a new ZODB, instantiate the tool, and push a button to reload it. Zope 3's "filesystem synchronization" capability is similar in concept, although I don't know if that has been maintained recently. > I'd be interested in seeing the particulars of how > you guys do that stuff. I do it all the time for customer jobs and there are examples in CMF for Zope 2 (e.g. the "SiteGenerator") but I don't have any code that uses Zope 3 that does site generation. > I've yet to run across a direct > mention of how to create an arbitrary ZODB and > start reading and writing objects.

There are tons of examples about how to access ZODB data outside of the context of Zope around, do a little googling. The thing that might make it a little mindbending is that "accessing data in ZODB" is just.. Python. You open the database, get the root Zope object, and then traverse to an object in the database (usually via getattr or getitem or whatever the folder API is) and call methods on it or read attributes from it or whatever. There's really not much to it. It's largely the same as writing code in your content classes, but you can do it from a Python prompt. Zope 2 has "zopectl debug" which dumps you off at a Python prompt with the name "app" built in to the root Zope object. Note that this is not particular to any version of Zope. Zope is just a consumer of ZODB, and the issues are the same no matter what consumer of ZODB you're using. - C From alen.stanisic at gmail.com Wed Nov 30 02:02:37 2005 From: alen.stanisic at gmail.com (Alen Stanisic) Date: Wed Nov 30 02:02:53 2005 Subject: [Zope3-Users] need guidance In-Reply-To: References: <6A5A9B2E-1F2F-42D7-B56A-73E21BD41D0C@plope.com> Message-ID: <1133334157.3761.76.camel@localhost.localdomain> Hi Brad, On Tue, 2005-11-29 at 21:07 -0600, Brad Allen wrote: [...] > Ok, so this kind of discussion makes me wonder how much I can do > without ZODB, or at least whether I can just use the ZODB files like > any other binary files in the SVN repository.

I might be missing something but not sure why would one want to store a database in SVN. I could understand that people doing TTW Zope 2 development would have source code in ZODB but Zope 3 does not have any TTW development functionality at the moment and all of your source should be on the file system. Python scripts could automate building a site or site utilities and I would have that sort of stuff in svn. But as far as persistent content goes this is more of a data backup/migration issue. fssync I think was mentioned on the list for pulling content objects out of ZODB in Zope3 on the file system but not sure if it is available yet.

For a production alternative, he pointed to the generations tool.

Whenever I am told by client that they want me to build an application for them, and they want to be able to add data/content while I do it, I either gently educate them on the proven process that we use, or I walk away from the project. Maintaining content during development is almost always a nightmare. There are tools to use to enable this... approach... but in my mind (and many others') it's just not a good way to do development. To come a little closer to answering your question, the only time that I have ever needed this kind of thing is on projects where we were delivering a product to multiple clients, pre-populated with default content. All of that content was added via python. > I'd be interested in seeing the particulars of how > you guys do that stuff. I've yet to run across a direct > mention of how to create an arbitrary ZODB and > start reading and writing objects. As soon as you create an instance of a content object, you've written to the ZODB. Whenever you render a page that presents a content object, you've read from the ZODB. z3 "protects" the developer from the ZODB. You never have to do direct reads/writes. You're simply operating within a z3 "app"... As for particulars, there are several emails in the archives for this list that detail z3 site setups. Even better, there are examples in the wild. IIRC, the cubic project had an example for this, and the "worldcookery" demo site might too. I'd certainly check out schooltool to see what they have done. Code-based site creation/setup/configuration will provide you with lots of ideas, hands-on examples, and a good sense of how to approach this. > That seems to > be a big piece missing from my understanding > of how to work with Zope 3.

If so, you're going to want to spend some time looking at zope.app.zapi (a lot of which comes from zope.component). In particular, the createObject() function. Take a look at those projects I mentioned above... and other folks may have good suggestions for code examples on site creation and pre-population of content.

Yep, SVN is the way to go; we do this in Zope 3 projects all the time. Since no code lives in the ZODB, there is no need for sharing ZODB content.

Well, I generally try to follow an iterative approach like that described in Agile or Extreme Programming styles ( ). The idea is to get something into production very quickly, let users bang on it, and then produce a new version based on feedback from users...and then do it again, and again, etc. There is no big lead time for "development-only"; the cycle is more like develop-release-use-develop-release-use, etc. During that cycle, end user data needs to be carried over to each new version.

Hmm, again, I think you *might* want to stay away from an approach that interacts directly with the ZODB. Unless you're not using z3/Zope 2... If you want pre-populated content in a z3 project, you probably want to be creating site instances to which you would add utilities and content.

Well, it's a great idea if your application is non-zope python with a need for "versioned" storage. It's not such a good idea if your application is a zope app because those app servers do so much of the work for you, with many years of honing put into them. The best thing to do is learn how to use the app server/framework such that your work is minimized (both short- and long-term) and such that the final product is a stable as possible (building on prior, tested, and proven work). Direct access in a z3 app is usually made for debugging purposes, and used with the pdb, can be very effective for hunting down and solving issues. As per your other email, the reason you had problems was because your z3 instance was already running. If you are not using ZEO, you need to stop z3 in order to gain access to the ZODB. Have you seen Benji's quick start guide? In addition to Stephan Richter's book, you ought to read Philipp von Weitershausen's book too. As of zope3.1, it's a little out of date, but only in a few areas. The conceptual explanations and careful, hands-on, examples-based approach is pure gold. His and Stephan's book are the perfect couple ;-) Links: http://worldcookery.com/ (Philipp's book is here) http://www.benjiyork.com/quick_start/ In addition, I've written a python script that auto-generates a starter z3 project for you, after asking a couple questions. If you want to use it, I'd be more than willing to answer any questions about it (an thus improve it) off-list. You can download it here: http://www.zope.org/Members/adytumsolutions/z3project_starter I'll got back to your original post and try to do a better job of answering your questions. d From dman at dman13.dyndns.org Wed Nov 30 14:39:02 2005 From: dman at dman13.dyndns.org (Derrick Hudson) Date: Wed Nov 30 14:41:45 2005 Subject: [Zope3-Users] Re: need guidance In-Reply-To: References: <200511300755.10932.srichter@cosmos.phy.tufts.edu> Message-ID: <20051130193902.GB31815@dman13.dyndns.org> On Wed, Nov 30, 2005 at 01:25:57PM -0600, Brad Allen wrote: | At 7:55 AM -0500 11/30/05, Stephan Richter wrote: | >We are currently not supporting TTW development.

FWIW, I wouldn't characterize the system into which those users put content into as a development system (aka development sandbox). Instead I'd call it a "demo" sandbox. Sure, the data in a demo sandbox needs to be enduring or you can't do iterative development because the customer will have no frame of reference between iterations, as all of their content will be gone. But data in a *development* sandbox is not very interesting and can be changed or thrown out at will. For example, I really don't care what's in a news article on my development sandbox. If the title of a news article says "Bush Invades Grenada" or "Ipsum Dolorum", it's all the same to me. I'm not actually reading the content, I'm just making it possible for the customer to add and change content abstractly. What the content says has no value to me. But there is the issue of keeping the demo system up to date while I do development because it *does* have value to the customer, so it's of course something that needs to be dealt with. So to get there, the mechanics I use are like this: - I create a buildout that builds the software I need to create a sandbox. Typically, this is Zope, ZEO, maybe a relational database, maybe an LDAP database, and so forth. I've done this many times, so it typically only takes me half a day or so, because I steal judiciously from other buildouts I've done. The job of the buildout is to put files on the filesystem. - I create a site generator, that puts some data I need into the ZODB. The job of the site generator is to put data in the ZODB. This also takes just a little bit, typically, because I've done it many times. - As I do development, I create scripts which evolve the database content from one code generation to the next as necessary. When I want to set up a new development sandbox, I run the buildout and the site generator on my own system. Then I continue to write code. When I finish "iteration 1", I set up a demo sandbox for the customer on one of his systems using the same buildout and site generator mechanisms. I continue developing in my development sandbox on my own system. In the meantime, presumably my customer is using and evaluating the "demo" system, which is running a only-slightly-older version of the code than what exists in my development sandbox, and also contains "real" data due to the fact they're adding and changing content. The customer never sees my development sandbox, only I do. I don't have his new content, but I don't really care. I'm able to deal more abstractly with the problem we're trying to solve than he or she might be, so having the most up to date content (or sometimes not having any content at all) in my development sandbox is not really an issue for me. In the meantime, if I'm working with other developers, they also run the buildout and site generator code and work in a sandbox *on their own system*. They never see page renderings generated by my development sandbox. I never see theirs. When we need to share code, we do so by checking our Zope product code in and out of CVS or subversion. We maintain the site generator and buildout as necessary as things change. As we move towards another iteration, if I need to, while I'm writing code, I write evolution scripts that are capable of fixing ZODB data in place between milestone revisions of code. I happen to know exactly when I need to do this, because I've been working with ZODB for many years. Other developers working with me do the same. When the project reaches a development milestone, I push out my development code to the customer's demo system and run the evolution scripts on the demo system. Their content remains intact, and they begin evaluating again and we start all over again for the next milestone. You say above that there's no big lead time for "development only". If you mean that you can't make time to do the above, I can understand the sentiment; I've heard it many times. But I just haven't found any other sane way to do it over the years I've been using Zope, so I feel like I've learned how to do this "the hard way" and I think it has a lot of value; every other method I've tried falls down in one or more important ways, particularly when I need to do collaborative development.

Do you have a zope2 background? With a background in zope2 and twisted, I found z3 very easy (delightful) to learn.

You will definitely want to start getting familiar with pythonic site creation in z3, particularly, setting up a catalog (IntId, Catalog, Index-creation, etc.). All of my query needs are met (so far) by simple python calls to catalog.SearchResults and then a lambda for sorting.

Perhaps I can clarify with a typical example: * you have a z3 project, all the code is on the file system * you will create custom content objects * you will create a "skin" for the project -- this is how it will look to end users * you can use the ZMI for administration tasks (such as creating/editing content) -- you can customize the ZMI to look like anything you want * you can modify your custom skin to present various editing/management options to the end users Perhaps this makes thins more clear? > Here is another question.

It sounds like the 'generations' framework is what you need. In your cycle you will develop and once you release version 1, a production system will be deployed.

He is talking about techniques to upgrade the software on a production system without losing preexisting data on that production system. During development and pre-release testing you won't have any critical data and each developer can simply recreate a new ZODB to work with. For more automated and repeatable testing your team should create some sample data and the scripts to populate a new installation with that data. If you don't do this then each time a developer or tester starts over with a clean database, then will need to expend time manually creating ad-hoc sample data to test with. The difference is the development environment vs. the production environment. HTH, -D -- A violent man entices his neighbor and leads him down a path that is not good.

In particular, I am tantalized by the paragraph above ;-) As I alluded in a previous post, this has been a very painful point for myself an other developers with whom I have worked. For one client, we used the CMFPlone.MigrationTool on a Zope2/Plone project where content addition was occurring throughout the development phase. I found the tool cumbersome and the whole process most painful and distasteful. Do you employ an analogous tool or elegant manual approach for z3 projects?

I was an instant z3 fan. I did spend some time trying out Zope 2 a couple of years ago, but didn't get very far past the basics. That was before I had really gotten into Python. What got me interested in Z3 was that our local Python user group (http://www.python.org/dfw) has been recently looking at a variety of Python web frameworks. Based on reading parts of Stephan Richter's Zope 3 Developer's Guide, I got the impression that Zope 3 was the most mature and featureful available. The intros to chapters 7 and 8 had some inspiring bits about the kind of experience and thinking went into the architecture of Zope 3. We had some meetings involving getting Zope 3 up and running on Ubuntu, the MessageBoard tutorial, etc. After awhile, I realized that we really should have started with the Philikon book first (Web Component Development with Zope 3), because it spent more time explaining the basics (like TAL and METAL, for example). I'm still going back and forth between the two books as I continue learning Zope 3. Btw, I found that the cheapest place to buy both Zope 3 books is Nerdbooks.com. I'm a bit biased, because Nerdbooks provides a meeting space for the DFW Python user's group, and I want to promote Nerdbooks as much as possible due to their generosity in hosting user groups in the Dallas area, as well as the way they provide an unusual combination of a vast technical book selection with the lowest prices around (lower than Amazon by a good bit). As for the easiness and delightfulness of learning Zope 3, that's not the general perception in our Python user group, and clearly a big part of the Python community is diverted into other frameworks such as Django, TurboGears, and TwistedWeb. How to improve the perception of Zope 3 could probably be a separate discussion thread unto itself. I favor the notion of making a separate Zope 3 site, or at least clearing out the old, outdated documentation at the current site. For a newbie, it's hard to tell what's current and what's outdated.

Ok, so using the app/server framework to read and write from ZODB is the way to go. I'm trying to understand exactly how that works. The books show how to register components using ZCML, but that doesn't create instances, right? As far as I can remember seeing, a human has to click something in the ZMI Add menu to create an instance in the ZODB. Meanwhile, the chapter in Philikon's book on persistence just shows how to create persistent classes and talks about how they work, but it doesn't say anything about how to insert an instance into ZODB. I guess this whole topic wasn't really explained in the books, unless I missed something (quite likely).

Last year, Jim was nice enough to finish the "generations" machinery for Z3 which to my knowledge currently ships with Zope 3. You can take a look at it at http://svn.zope.org/Zope3/ trunk/src/zope/app/generations/ . I created a Zope 2 product that used this machinery at the time... it's available via http:// cvs.zope.org/Products/zzz_generations/ . Docs are pretty slim for the Z2 version, so it's not immediately useful, but if you can figure out how to register a product with an initial version, it becomes useful thereafter. I use zopectl debug to do that myself. ;-) The nice thing about this kind of tool is that there is exactly one action for its UI consumers to take: upgrade. The only way they can screw it up is to *not* do that. ;-) - C From duncan.mcgreggor at gmail.com Wed Nov 30 19:01:35 2005 From: duncan.mcgreggor at gmail.com (Duncan McGreggor) Date: Wed Nov 30 19:02:04 2005 Subject: [Zope3-Users] Direct ZODB access in a Zope3 instance In-Reply-To: References: Message-ID: <74821222eea2a36da03359c810ca7aa8@gmail.com> On Nov 30, 2005, at 3:07 PM, Brad Allen wrote: > Ok, so using the app/server framework to read and write from ZODB is > the way to go.

But it makes more sense that most other ways of doing things... the problem is that we've gotten used to mixing configuration and code. ZCML is the quiet hero in this regard: it gives us the long-needed tool to separate configuration from application. And if you think about it, this really makes the most sense. If you've got a hundred clients that want to use your product, each of those clients should only have to change configurations, not the actual code itself. Additionally, I really like the clean approach that z3 has as a result of ZCML: if you haven't configured it, you aren't going to see it/use it (as an end-user, I mean). This appeals to the security engineer in me ;-) It also makes things wonderfully simple as far as enabling/disabling features. Back to your question: ZCML doesn't actually do anything -- z3 looks at it to "know" what to do. So, in order for z3 to know about content objects, custom views, resources like images, etc., you have to put it in ZCML (well, for some things you can put it in python, too). As far as the ZMI is concerned, there are entries you need to make in your configuration files that tell z3 to (for instance) have a custom content object appear in the "Add" menu. If you have made that entry in your ZCML file(s), users will be able to click something in the ZMI, and a content instance will be created. ZCML is confusing at first because of the many features and the conceptually different aspects of application configuration for which it is responsible. To keep all of these straight, I ask myself questions like: * is this part of my code just purely content object? * is this part application internals? * is this part management UI related? * is this part content presentation? * is this part just look at feel (page structure and CSS)? I tend to put each of those in their own areas or sub areas (read "directories"). They each have different ZCML files; a top-level ZCML file includes the ones from the next level down, etc. The best way to come to term with this stuff (in my mind) is to jump in and start using it, even if it doesn't make sense at first. Much will be revealed simply trough the doing of it. BTW, As a result of practices such as these, the z3 projects I have worked on have been the conceptually best organized projects I've ever been a part of. > Meanwhile, the chapter in Philikon's book on persistence just shows > how to create persistent classes and talks about how they work, but it > doesn't say anything about how to insert an instance into ZODB. It's done for you "automatically" -- when you click "add my page" on the ZMI menu (given that you have a content object called "my page"), it is inserted into the ZODB. >> Yeah, I think you're looking for code-based content addition -- is >> that right?

To "get a hold" of certain components, you use various useful functions that are provided in the zapi (many of which come from the components package). One of the most common ways of getting a hold of an object or object type is by interface lookup. So, if you want to create something, you'll need a context for that object's creation. Quite frequently, that context will be a site. There are many ways to do this, and it depends on how you have designed your z3 project. I'm not being deliberately obtuse ;-) This is the point where you need to look at sample code, or pour over book chapters. I would like to post some of the code that I've done that's related to the topic, but most of it is very special-case... and it assumes fairly detailed z3 knowledge. What we really need for discussions like this is some nice demo code... does anyone have something like that? I know Gary Poster emailed the list with some best practices for getting a site and adding a catalog to it. But, IIRC it was not code (maybe some pseudo code?). Ah, here it is: http://mail.zope.org/pipermail/zope3-users/2005-September/001078.html Here's a thread for making a folder a site: http://mail.zope.org/pipermail/zope3-users/2005-May/000548.html It might be worth the effort to start up a peer-review thread here that demos a simple site build, pre-populating with some simple content. That would be a fantastic resource for folks. Hmmm. In fact, it might be a good idea to do another z3project_starter script that included code like that... You're going to want to read up on interfaces, component-based design, z3 utilities, and subscribers. And there's lots of super smart dudes on the mail list that know this stuff inside and out who can assist as your getting your head around this stuff. It's totally worth the effort. I've used tons of web frameworks, and as far as I am concerned, this one (z3) takes the cake. IMO, component-based development is the only way to fly ;-) d From brad at allendev.com Wed Nov 30 20:56:30 2005 From: brad at allendev.com (Brad Allen) Date: Wed Nov 30 20:56:33 2005 Subject: [Zope3-Users] Direct ZODB access in a Zope3 instance In-Reply-To: <74821222eea2a36da03359c810ca7aa8@gmail.com> References: <74821222eea2a36da03359c810ca7aa8@gmail.com> Message-ID: Brad Allen wrote: >>Meanwhile, the chapter in Philikon's book on persistence just shows >>how to create persistent classes and talks about how they work, but >>it doesn't say anything about how to insert an instance into ZODB.

Yes, I learned that early on in the MessageBoard tutorial. But all the talk about doing automatic ZODB regeneration in the other thread implies the ability to create object instances in the ZODB at specified locations WITHOUT having to manually click for every single object instance.

One of the most common ways of getting a hold of an object >or object type is by interface lookup. Ok, suppose there is a ZPT Page object located in the ZMI/ZODB in the following folder path: /SiteName/UserContent/Articles/IntroText To "get ahold" of the object from within Python...by that I mean bind a variable name to an object...you say I should use an interface lookup. I don't get it. I've seen how to validate whether an object implements an interface, or whether an interfaces is providedBy an object, but I don't know how to lookup an object via an interface. In the case of a ZPT, it implements a lot of different interfaces : zope.app.zptpage.interfaces.IZPTPage zope.app.zptpage.interfaces.IRenderZPTPage zope.app.publication.interfaces.IFileContent zope.app.annotation.interfaces.IAttributeAnnotatable zope.pagetemplate.interfaces.IPageTemplateSubclassing persistent.interfaces.IPersistent zope.app.container.interfaces.IContained Which one would I pick to use for a lookup? And if I picked the right one, wouldn't I get back a list of objects, rather than the specific one I want? I guess I'm asking if there is a function that will allow me to do this: introText = getObject ('/SiteName/UserContent/Articles/IntroText') From there, I'd expect to be able to rename the object, move it to a different directory, delete it, copy it, put it inside another object, change attributes, call methods on it, etc. Am I misguided in wanting this? I am just wondering how to get at user generated data, manipulate it, export it, etc. I've seen how to get at objects in the ZODB via TALES expressions, but all I can with that is display it, right?
