Zope X3 3.0.0 RC 2 released
by Stephan Richter 05 Oct '04

05 Oct '04

Hello Zope community, The Zope 3 development team is proud to announce the second release candidate for Zope X3 3.0.0. Hopefully this will be the last one. Zope X3 is the next major Zope release and has been written from scratch based on the latest software design patterns and the experiences of Zope 2. The "X" in the name stands for "experimental", since this release does not try to provide any backward-compatibility to Zope 2. Downloads http://zope.org/Products/ZopeX3 Installation instructions for both Windows and Un*x/Linux are now available in the top level README.txt of the distribution. The binary installer is recommended for Windows. Changes since RC 1 - A security related bug was fixed. See the "Issue Collector":http://collector.zope.org/Zope3-Dev/286 for details. - Fixed a bug that would crash the API Doc tool, if no default skin was specified. - Fixed a couple of typos in the documentation. - Updated to latest version of the ZODB, version 3.3 final. - The 'zope.app.observable' package was removed from the release, since it was unusable. - The 'zope.app.i18nfile' package was removed, since it was always just a demo to demonstrate the internationalization of content. However, it has not been maintained with regard to recent changes and does not function properly anymore, so we decided to remove it. - Updated translations. Enjoy, the Zope 3 Development Team

Using string as object name?
by Duane Raymond 05 Oct '04

05 Oct '04

Hi, I'm trying to create a generic python script in Zope that will translate any SQL query into a dictionary. I've got it working when I put in the name of a specifc SQL query name, but I can't figure out the syntax/function to take a string that contains the ZSQL method name and use it in the code like I have below (which produces attribute errors): columns=2 # the number of columns needed query = "sql_getMySQL()" myObject = getattr(context,query) qresults=context.myObject.dictionaries() # this is done to get a real list return [qresults[index:index+columns] for index in range(0,len(qresults),columns)] Any suggestions?

Should the ZPT list be retired?
by Evan Simpson 05 Oct '04

05 Oct '04

The ZPT list was created when Page Templates were new and shiny, and there was a decent volume of discussion about their design and usage. These days, there are only sporadic non-spam postings, and all of those could probably live comfortably on either zope-general or zope-dev. Should this list be retired, or is there a good reason to keep it alive? Cheers, Evan @ 4-am

But when I try to show anything to my boss with his IE, the Zope is "crashed". I say crashed, because I must restart it to work it again... (And the too many computer user use IE... :-( ) The 2.7.3b is buggy, so I don't have any chance, only downgrade. Please help me: Is the 2.6.4, or 2.6.3 is have this problem ? Is 2.6.4RC2 working good ? I must downgrade, but I don't know, what the version I choose to eliminate these session errors. Thanx for help: ft

i18n ".pot" files: Edit with Web Application?
by Hermann Himmelbauer 05 Oct '04

05 Oct '04

Hi, I am currently involved in a Zope project. Our Project needs to be internationalized, hence I took a look at the i18n layer. My problem now is that our translators are no programmers, hence they won't be able to edit the ".pot" files. (Maybe this sounds silly, but they do not close bracktes etc., therefore I have to check the files afterwards by hand which is very cumbersome). What I consider is presenting the translators a web application which reads the .pot file, presents the user the original translation including the file comments (so that people know where the text is situated) and displays some text fields where the user can input their special translation. There they can easily translate the messages and afterwards I only have to copy the ".pot" file to the right folder. What I wanted to know if perhaps someone wrote such a web application or something similar that I can use. If nothing like that exists, I consider writing this on my own, perhaps you have some helpfuls hints/suggestions what features the application should have and how one should implement this. What I moreover thought about if it's possible to present the user the actual page and let him somehow "click" on the messages which opens up a popup or something similar and lets him put in the translation directly. But maybe this is too complicated, moreover these translations would only apply to web pages and not to script messages.

I need to call a xml-rpc subroutine from javascript. How is this done? In my daemon I have subroutines such as emailInfo, officeInfo, pwdInfo,... I call these subroutines in a client function called userInfo(username): def userInfo(userName): server = xmlrpclib.Server("http://tweety:8080/RPC2") email = server.da.emailInfo(userName) office = server.da.officeInfo(userName) pwd = server.da.pwdInfo(userName) acct = server.da.acctInfo(userName) dir = server.da.dirInfo(userName) info = {'email' : email, 'office': office, 'pwd' : pwd, 'acct' : acct, 'dir' : dir } return info How do I call userInfo in a javascript function? Thank You in Advance, Laura

tal:attributes and onClick

The following code performs an expansion using the onClick. <a href="#" tal:attributes="onClick string:expandIt('${resString}');; return false;"> <IMG NAME="imEx" SRC="triUp2.gif" WIDTH=15 HEIGHT=15 BORDER=0 ALT="Expand/Collapse Item"> </A> Is there a way to add a tal:define on an onclick also? I need to define the following: tal:define="info python:here.userInfo(username)" but I want it defined in the on onclick as well. Thanks.
