Help System Menu patch
by Bill Anderson 25 Nov '00

25 Nov '00

After working with the Zope help System a bit, I got very annoyed that there was no consistent ordering to the tree. For example, you could repeatedly click the contents tab link, and watch it reorganize itsself. Attached is a patch that sorts everything by id. Why id? Because then I can make my help menu item id's a numeric sequence, and put the topics in a specific order. Example: Membership Overview Membership Conventions Rather than the order being random. Attached is the patch. patch from the Zope root directory. Once applied, you *don't* need to restart zope to see the change.

All channels in medusa occupied?
by Carlos Neves 24 Nov '00

24 Nov '00

Hello, everybody, I am writting a little something wich gets some concurrent connections and leaves them hanging until there is data to update. My obvious problem is that my zope handles 4 connections wich wait for a period of up to 5 secs, to give the viewer the notion of active content. i.e. if there is no data it holds as if waiting for a connection, and once it has it, the page is refreshed. then a meta refresh requests it again, and it holds until there is info... Problem starts because all 4 connections get occupied and waiting, so any request for a common page in my zope will wait up to 5 secs for a chance to grab a connection. Is there some way aroud this? I confess not having put much of an effort in resolving this until now, but it's not the first time I hit the wall with my head for days, only to see my problem solved as soon as I posted it to/searched the list. So let's get parallel this time and I'll start diggin' into this as of *now*. thanks -- "Kill processes, not people." - Larry Cohen Carlos Neves cneves(a)ruido-visual.pt

Interface localization: zzLocale 0-0-4a release
by Yves-Eric Martin 24 Nov '00

24 Nov '00

Hello, Since the SkinnableAndLocalizable project is on hold, and since people here in Japan and other non-english speaking countries have repeatedly expressed their wish for localized versions of Zope, I decided to continue zzLocale development and turn it into an actually usable Product. Here is a big step towards it: zzLocale release 0-0-4a. zzLocale is a Zope locale support Product that provides a framework for Zope interface internationalization. Main new features are: o New failover code that should break less stuff (previous version broke various Products, like ZGadflyDA or LoginManager. All reported broken Products are now working) o Localization of management tabs o Localization of buttons (all should work now). o Fixed hideous bug that prevented uninstall Altogether, this should hopefully make this version actually usable: a few things are still not internationalized (like MessageDialogs), but it should *work*. Please email me if you can still find things that break when using zzLocale. Download urls: from zope.org: http://www.zope.org/Members/yemartin/zzLocale from zope.ne.jp: http://www.zope.ne.jp/users/yemartin/zzLocale Note that no actual localization file is provided with this release. Language packs will be made available as we receive translations. (If you have a few hours to kill, how about translating Zope into your mother tongue (if it is not English)? ;) ). Cheers, -- Yves-Eric Martin Digital Garage Inc. yemartin(a)garage.co.jp

Principia-Version
by Matt Hamilton 24 Nov '00

24 Nov '00

Dear All, I am trying to use Versions and CatalogAwareness at the same time and am running into problems due to any updates being done whilst under a version cause the Catalog to become locked to any other updates outside the version. As a workaround I want to modify CatalogAware to not actually do any index operations when an object is in a version. But how do I tell (from python) if I am in a version? Looking at the management pages I see <dtml-if Principia-Version>, but I can't seem to access the same attribute from within python. Any ideas on how to do this? I have searched all the docs, archives and code and can't find any examples of accessing this information from within Python.

Unit testing, ZUnit
by Lalo Martins 24 Nov '00

24 Nov '00

We (I and Hiperlógica) started to develop a Product we called ZUnit, intended for XP-style unit-testing Python-based Products in a full Zope environment (with a real ZODB, REQUEST, RESPONSE, etc). We first conceived it as a kind of Zope-based version of unittestgui.py - you create a "TestRunner" object giving it the package, module and name of a TestSuite object generator (see the PyUnit documentation) and inside it you may click on some widget to run the tests and produce a "TestResult" object which you can inspect later. Does this sound like a good design? Then I figured in the long run a Product isn't the best sollution; instead, fiddling with App/Product* sounds more like it, to allow developers to register tests just like they register classes, ZClass superclasses, _misc and help. Of course, just like the current registerHelp and others, it wouldn't be mandatory and not using it wouldn't break anything. Then, in the Product's page in the Control Panel, there would be a tab "Test", where you'd be allowed to run the unit tests. What do people think of this? What does DC think of this? Can I go ahead and develop it in this direction? (I will create a proposal in dev.zope.org, but I want to get some feedback here first to flesh out the proposal a little more.)

least hacky way of cataloguing multiple dates
by Andy McKay 23 Nov '00

23 Nov '00

I have multiple dates in a field as lines. What I would like to do is call objects queried on those dates... this seems very flaky has anyone tried this? The best result so far is to hack the date in a string the text index likes such as Date2000-10-11.... ugghh. I can then query the text index. TIA -- Andy McKay, Developer. ActiveState.

ZPatterns - help!
by bentzion＠bellatlantic.net 23 Nov '00

23 Nov '00

I am trying to create 'virtual' DataSkins that totally live in a SQL database. How do I create a new item in a rack without providing an initial ID for the object? Here's what I've been doing so far... 1. I have Storage set to "loaded by accessing attribute 'id'". 2. I have an ADD trigger that creates a MySql row and returns the LAST_INSERT_ID() as "id" ("Keeping:id=RESULT.new_obj"). 3. I have a CHANGE trigger that updates the MySql row with attributes. 4. I have a CatalogTrigger. Now it almost works when I try to add an object with key=random() by: <dtml-let ni="newItem(key)" nips="ni.propertysheets.get('Basic')"> <dtml-call "nips.manage_changeProperties(REQUEST)"> So what I belive this is doing is creating a temperery object then changing it's ID (which sounds very screwy). The problem I am having is first of all the Catalog is indexing the temporery random key not the one returned from the CREATE trigger. Please advise. Also in my CHANGE trigger I am calling SQL like this: UPDATE sc_account SET <dtml-in CHANGED_ATTRS> <dtml-var sequence-item>= <dtml-var expr="_.getattr(object,_['sequence-item'])" sql_quote> <dtml-unless sequence-end>,</dtml-unless> </dtml-in> This updates all my 'string' fields but not the 'int' ones I think because they are quoted by "sql_quote" (although I'm not sure). Please advise. I know this is a rambling email but I would greatly appreciate your help in creating DataSkins that are stored in RDBMS not persistently. Once I get this working I'll post a full How-To (unless there is one already that I've missed). -Ben

Method calls
by Roch'e Compaan 23 Nov '00

23 Nov '00

I have a method called getModulesForProduct to which I pass a ProductID eg: <dtml-in "Products.Modules.getModulesForProduct(this(), _, ProductID)" sort=name> If ProductID is passed on from a form variable it works fine. If I set the ProductID through REQUEST.set: <dtml-call "REQUEST.set('ProductID',_.str(Product.id))"> , I get a TypeError: Error Type: TypeError Error Value: hasattr, argument 2: expected string, int found I've been banging my head against this problem the whole day so help would really be appreciated.

ZPatterns: Properties that are objects
by Roch'e Compaan 23 Nov '00

23 Nov '00

I use external methods to set properties that are objects for my Dataskins. I have a Customer Dataskin with a property Address, that is another Dataskin. In my editInstance for Customer I change the properties of Address directly: <dtml-call "propertysheets.basic.manage_changeProperties(REQUEST=REQUEST)"> <dtml-call "Address.propertysheets.basic.manage_changeProperties(REQUEST=REQUEST)"> but this results into a keyError afters a couple of edits. When I get the Address directly from the Rack it works fine: <dtml-let addr="Contacts.addressRack.getItem(id)"> <dtml-call "addr.propertysheets.basic.manage_changeProperties(REQUEST=REQUEST)"> </dtml-let> Why does the "simple" way of doing not work consistently? Is this a bug, maybe? Roché
