question: upload files to folder AND database
by Olivier Wambacq 08 Mar '06

08 Mar '06

hello, is it possible to upload files in plone, using a form (like the form in plonelocalfolderNG) AND sending a url to that file + additional information to a database using popy connection? I can upload files using plonelocalfolderNG, but I can't send any more info with it. + I need to sort them, so I need some more info (like category, author, ...) in a database to perform my sql on. also, I want to let users upload using a form, not with the add tab button. I tried watching the plonelocalfolderNG code, and making my own, but I can't get it to work. thanx in advance, Olivier

repozo.py
by Dennis Allison 08 Mar '06

08 Mar '06

We are (finally) moving to repozo for our backups. We are running a mixed collection of Zopes -- mostly Zope 2.7.6, Zope 2.8.X and Zope 2.9.0. For the near term we cannot move to a single release. There are differences between the versions of repozo distributed with the different Zope systems. I assume that the they are backward compatible and that the repozo.py shipped with Zope 2.9.0 is compatible with all variations of the Data.fs format. --

Assuming you have read and practiced the 2 chapters on ZPT in the Zope book I would also recommend peterbe's "DTML2ZPT Conversion examples", even if you have never done DTML, these are a collection of common code snippets: http://www.zope.org/Members/peterbe/DTML2ZPT After that keep in mind that anything complicated enough to need "python:" in a TAL statement should likely be moved out to a python method. (That could be either a python script through the ZMI, or even better a method of your filesystem based python product.) The results of the python method can then be placed in the option space and accessed very easily from the ZPT. A common usage scheme is to always call the python method through the web, which assembles all needed data and then returns the ZPT with the data as parameters. Have fun! Regards, Sascha

newbie Simple WebSite Construction Using Zope and Search
by Matt Slavin 08 Mar '06

08 Mar '06

Hi, I am trying to use Zope to create a very simple company website (about 40 pages, or so) with the intention of having the flexibility to expand functionality etc in due course. I have very little Python / DTML experience, but have managed to set up the site using includes on the main index page and then use aquisition to provide the content within each section. I'm not sure if this is a safe - or correct way of going about it, but it seems ideal for our purposes. The navigational menus dynamically include a link to each sub folder - ie website/services/ - and navigating to a section, index_html is automatically shown. The "mainContent" variable is then dynamically placed into index_html. (So there are separate mainContent dtmlDocuments in About Us, Services etc..) This means we can keep the content completely separate, and do not have to include headers, footers and other includes within the mainContent variable. Brilliant. However, when using the search script - http://www.zope.org/Members/Ioan/SiteSearch - results return a link back to the dtml_Document file mainContent, which gets displayed without any of the header of footer information. Is there any way to render the page with header and footer info? (By, I guess, redirecting the page to the containing folder, so that it pulls out index_html instead...) Any thoughts on this would be gratefully received - as I'm not sure this is the best way of using Zope, but it seems so much better than using plain old included variables. kind regards, Matt --------------------------------- Yahoo!

Redirect Exception and Five
by Santi Camps 07 Mar '06

07 Mar '06

Hi all, I have a problem developing a Product using Five. When a Redirect Exception is raised from a PluggableUserFolder inside my product, it is not handled by the publisher, and I have an error message instead a browser redirect. The same test inside a normal Folder works fine. I'm using Zope 2.9.0, and tried to add this ZCML statements, but I've no luck, and I can't find any other message talking about this. <five:traversable class="OFS.Application.Application"/> <five:traversable class="OFS.Folder.Folder"/> <five:traversable class="zExceptions.Redirect"/> <five:traversable class="Products.PluggableUserFolder.PluggableUserFolder.PluggableUserFolder"/> <five:traversable class=".folder.APWebFolder"/> Anybody knows what could happen ?

Using PUT_factory for objects outside of ZODB
by John Barham 07 Mar '06

07 Mar '06

I want to be able to intercept PUT requests to Zope to store objects outside of the ZODB by storing the body of the PUT request in an SQL database. I've written a PUT_factory external method that calls the function PUT_ParameterFile defined below: ========== [...boilerplate Zope imports...] class ParameterFile(Implicit): security = ClassSecurityInfo() security.declareObjectPublic() security.setDefaultAccess("allow") def __init__(self, context, job_batch_id, body): self.context = context self.job_batch_id = job_batch_id self.body = body def PUT(self, REQUEST, RESPONSE): self.context.SQL_UpdateJobBatchParameterFile( job_batch_id=self.job_batch_id, parameter_file=self.body) RESPONSE.setStatus(204) return RESPONSE def PUT_ParameterFile(self, name, typ, body): if typ == "text/plain": return ParameterFile(self, name, body) ============= The ParameterFile.PUT method is being called, but then Zope returns w/ the error "Can't pickle <extension class __builtin__.ParameterFile at 72918728>: attribute lookup __builtin__.ParameterFile failed". Why is Zope trying to pickle the ParameterFile object when it's handling PUT itself? TIA, John

RE: [Zope] Re: Advice needed before settling on Zope
by Rainsford, David 06 Mar '06

I never said thanks to all you guys for your advice - it all came in very useful. In the end though, I have decided to go with another system, Knowledge Tree. The reason is that a) it's written in PHP, and all of us developers are fluent in PHP whereas there is going to be a learning curve with Python, and Zope. Secondly, it already provides 95% of what we need, much more than Zope, Plone and other Zope based management systems. I think building from scratch on top of Zope would have been too hard for us considering that our clients, whilst they haven't given us a specific timeframe, want the software up and running as soon as possible, and also we are juggling quite a few projects at the same time and to do it justice I think we would really have to immerse ourselves in Zope for a week or two which we don't have time to do. But thanks again, not just Maik but everyone who replied to my question. -----Original Message----- From: zope-bounces(a)zope.org [mailto:zope-bounces@zope.org] On Behalf Of Maik Ihde Sent: Wednesday, 15 February 2006 19:20 To: zope(a)zope.org Subject: [Zope] Re: Advice needed before settling on Zope Hi David, > We have to build a content/document management system for our company, > and I have been assigned to look into this and make a start. The system has quite a few requirements, which I'll outline below. As you might already know, there are quite a few CMS built on top of Zope2. Zope3 seems to be getting more and more momentum as people find out that it's concepts and ideas are really superior. > Version Control: we need quite complex version control. Lets say we > have document x. This document will be developed and worked on by multiple users. At the same time, this will also be translated into other languages. If a change is made to the English version, then that change will have to be made in other languages too. I think that in Version Control speak, the different languages can be thought of as different renditions. Version control is already used in various Zope-Products (CPS for example). So you need to keep track on multilingual Content here. The translations are to be done by human beings, though? Do you just want to create a new version in a certain workflow-state for the other language-versions when a new english version occurs? > Workflow Control: because of the number of people involved, we need to > have a Well, Workflows are there. In Zope2 Land You have DCWorkflow, some OpenFlow Variant and also AlphaFlow on the Plone Side. In Zope3 there is also a Workflow Package, so I think the Infrastructure is there too. > Document Management - the system is all about documents. They would > like the ability to organise the documents into different pages for people to download. They should be able to download older versions or different renditions. Also each document will be available only to certain groups or roles. No Problems here as well, especially the security model of both Zope2 and Zope3 is really well suited for such Applications. > Our client is quite specific about what they require and how they want > it to be presented, so ease of customisation and extensibility is a major factor. We have looked around at existing CMSes but have not found one that fulfills all of our requirements or that is customisable enough that we can fulfill our requirements with a bit of work. We looked at Plone, and then I decided we might be better off going down a level and building on Zope. Then definetely you are right in betting on Zope. I would even say, that it sounds like you should choose Zope3 - however this is hard to say, since your requirements are not very specific. But if customisation and extensibility are important then it sounds like Zope3 to me. >settle on Zope, would we be wiser using the 2.x version or the 3.x >version? I imagine that 2.x has more documentation and more addons >(e.g. for versioning, workflow etc.). Yes, but Zope2 is a complex Beast which has to carry a lot of historical weirdnesses around. Zope3 has a much better structure but there are not so many Addons available yet. I would advise that you have a look at the zope3 Malinglist and try to find out if the already existing Component Infrastructure roughly suits your needs. I mean Database Connectivity, LDAP and that stuff.
