Links? The jump to Zope 3 is a huge one, and it is no surprise that existing CMS's have not yet made it. I personally believe that the Zope 3 architecture is very compelling, and we are trying to leverage some of that for Plone. If you want to see an actual CMS implemented fully in Zope 3 you many want to look at Tiks, http://www.tiks.org/ . A large non-CMS application making use of Zope 3 is SchoolTool. There are many resources on the net describing the features and advantages of Zope 3. Alec

Hi, Right now I'm using Zope 2.8.1 with interface of plone 2.1.1 and Python 2.3.5. I'm planning to upgrade the version interested in migrate to ZOPE3.2 . Before that I need to know one thing. " Does Zope3.2 provides support to check last modified person's name in recent modified tab. ?" In Zope 2.8.1, In recent modified link it was always reflecting owners name, not the person who modified the file. Please provide me information regarding this.

overrides.zcml and localization in Zope 2.9
by Doyon, Jean-Francois 06 Jun '06

06 Jun '06

Hello, I'm trying to override Zope's localization mechanism with my own, as documented here: http://codespeak.net/z3/five/i18n.html And am not having any luck. <configure xmlns="http://namespaces.zope.org/zope" xmlns:i18n="http://namespaces.zope.org/i18n"> <i18n:registerTranslations directory="locales" /> </configure> <configure xmlns="http://namespaces.zope.org/zope"> <adapter for="zope.publisher.interfaces.http.IHTTPRequest" provides="zope.i18n.interfaces.IUserPreferredLanguages" factory=".i18n.URLLanguages" /> </configure> from zope.i18n.interfaces import IUserPreferredLanguages from zope.interface import implements class URLLanguages(object): implements(IUserPreferredLanguages) def __init__(self, context): self.context = context def getPreferredLanguages(self): return ['fr'] As best I can tell, the method never gets called, I've added print and raise statements and so on and yet nothing ever seems to happen. With the above example HTTP_ACCEPT_LANGUAGE still always ends up being en-us ... Also, locales/fr.mo exists. What am I missing here?

Templates vs DTML
by Dennis Allison 06 Jun '06

06 Jun '06

We've been using DTML but we are at a point where we could move to page templates. We are starting a major restruture and rewrite of much of the system and are debating moving to ZPT. Performance is potentially a major issue. We are using Zope 2.9.X, will eventually move to Zope 2.10.X and Five. Python 2.4.X. Has anyone done any benchmark comparison of the two design choices? For the same functionality, which performs better. No flame wars about which is better, just information about performance.

Using PIL 'inside' Zope
by Jamie Bullock 05 Jun '06

05 Jun '06

Hi, Does anyone know of a way to use the PIL imaging library within a Zope instance. If i do from PIL import Image I get Module AccessControl.ZopeGuards, line 284, in guarded_import ImportError: import of "Image" from "PIL" is unauthorized. You are not allowed to access 'Image' in this context Anyway to change this restriction? Is it advisable to change it? PIL works fine when using it via an external method, but this is a bit cumbersome for what I need to do. Advice appreciated. Jamie

Re: Any known leaks in ExtFile and OpenFlow?
by Michael Vartanyan 05 Jun '06

05 Jun '06

Hi all, One of my Zope (2.8.4 on Python 2.4.2, SLES9) sites constantly hits the memory limit. It makes heavy use of two products - ExtFile (1.5.0) and OpenFlow (1.1.0). ExtFile class (of ExtFile) and workitem class (of OpenFlow) are leading the refcount list with a not-constant but overall increasing numbers of references. Refcounts for both reach numbers that are incomparably higher than the numbers of their instances in ZoDB. I wanted to ask if there are known leaks in these products before going into (painful) hunting and debugging leaks in my own code. Thanks!

How to set selected items in multi-select list from lines property
by John Schinnerer 05 Jun '06

05 Jun '06

Aloha, I have an "add" form where a user can add an object. In one part of the form, the user selects zero or more options from a multiple select list. The selected options populate a lines property of the object when the object is added. I also have an "edit" form where the user can later edit these same objects they've created. They can use the same multiple select list to change the selected options. Of course the previously selected options (in the lines property) need to be displayed as such when they first visit the edit form. So... I need to know how to display the multiple-select list in the "edit" form so that the options currently in the lines property are set as selected. I suspect there is some very slick way to do this, maybe with TAL alone...? So far I am only coming up with what seem to be cumbersome solutions that have unecessary overhead (comparing a list option with every element in lines property via python script to see if it should be set selected, and repeating for every list option)...is there a better way? Any help appreciated. thanks, John S. -- John Schinnerer - MA, Whole Systems Design ------------------------------------------ - Eco-Living - Whole Systems Design Services People - Place - Learning - Integration john(a)eco-living.net http://eco-living.net
