I am trying to create a z-class (which resides in a product I have made) in a given folder through a python script. My syntax is obviously wrong (since it is not working), but alas I cannot find out what it is.. anyone? context.manage_addProduct['productName'].manage_z-class-constructor("spam") -jorg

Packless sessions with DBTab
by Chris Muldrow 11 Dec '02

11 Dec '02

I noticed that ExternalMount had been deprecated and replaced by DBTab. I'm in the process of attempting to set up some sort of nonundoing storage for 2.6's sessioning mechanics for use with a ZEO installation. Because all of the documentation is for previous versions of all the different pieces of the puzzle, I've succeeded in totally confusing myself. Is there a new procedure for setting up packless storage for use on Zeo clients? Which Berkeley DB are folks using with 2.6? Should I perhaps just take a long nap first? Thanks! Chris

Does anyone know where ZProject for Zope can be downloaded? I came across the Wiki for this product, but there's no reference to a site or individual who maintains it. Thanks Davis

uniqueValuesFor makes an unexpected evaluation.
by Lennart Regebro 10 Dec '02

10 Dec '02

I used the following dtml: <dtml-in "Catalog.uniqeValuesFor('countries')"> This works as expected, that is returning a list of the unique values in the "countries" index. But if I run this from a folder that is a subfolder to a fodler called "countries" then index_html gets called for this folder (which the failes, because the index:_html makes a call to REQUEST and it doens't get one). That makes absolutely no sense, and I can't even see why this would happen. Why does countries gets called when I do "Catalog.uniqeValuesFor('countries')". There are quotation marks around countries, it should be treated like a string. It seems to me that it's called during the interpretation of the DTML, because it seems that uniqueValuesFor isn't being called. Anybody have *any* idea?

[Bug] TALES in Zope 2.5.x converts "ConflictError" into "TALESError"
by Dieter Maurer 10 Dec '02

10 Dec '02

I know, I cross post... Please adjust the destinations as appropriate when you reply. In Zope 2.5.x, "Products.PageTemplates.TALES.Context.evaluate" converts most exceptions into "TALESError" exceptions. This is probably not a good idea for many exceptions. For "ConflictError" (and its subclass "ReadConflictError") it is definitely a bug. It prevents the usual automatic retry of the request and exposes an exception not understandable to a normal user. I think Shane has cleaned up the exception conversion for Zope 2.6. Therefore, I do not file a bug report to the collector. Dieter

Python Question: Morphing Classes?
by Johan Carlsson [EasyPublisher] 10 Dec '02

10 Dec '02

In lack for other Python mailing lists I send my question here (there ought to be someone with a bit of python-zen here ;-) I'm have a bit of a problem because I need to copy one object in the ZODB. Now the copy-and-paste support of Zope will not do it because it actually export/imports the object including all its sub object. So I have abandoned that idea (after an interesting attempt to export only the object (based on their oids), which was bound to fail. Anyway, there isn't any generic way to create an arbitrary product instance. Because if I could do that I could copy all the data into the new object, but I need to be able to handle any addable Zope object and they all got different init-methods requiring arguments. But I have tried another thing: Creating an instance (a) of the class C: pass, I can set the a.__class__=A (where A is another class), a will report that it is a instance of A and it will have all of A's class context. This look like a possible, even if not so less hackerish, way around my problem. Are there any traps I could fall into here?
