Hello all , I'm trying to display on the same page a table with (3 columns) with content from a list . I'm trying to batch the results so that every 3 elements anothe row is created. Can anyone give me a clue how to do that ? this is my code: <table tal:define="Rnumber python:context.cm1.content.specialfile.getList('link_list') ; batch python:modules['ZTUtils'].Batch(Rnumber,size=3,start=0)"> <th colspan="3">Main Title</th> <tr><th>Title 1</th><th>Title 2</th><th>Title 3</th></tr> <tr> <td tal:repeat="num batch"> <span tal:condition="python:num < 3" tal:replace="structure num"> content goes here.. </span> </td> </tr>  </table>

[ANN] Zope 2.8.5 released
by Andreas Jung 19 Dec '05

19 Dec '05

Hi all, on behalf of Zope Corporation and the Zope community I am pleased to announce the release of Zope 2.8.5. You can download Zope 2.8.5 from http://www.zope.org/Products/Zope/2.8.5/ Some new features of Zope 2.8: - ZODB 3.4 with MVCC (multi version concurrency control) support. MVCC solves nearly every problem with ZODB read-conflict errors which is very important for high-traffic Zope sites. - Extension Classes were rewritten as Python new-style classes making all features of Python new-style classes available in Zope objects. This includes support for cyclic garbage collection. - Integration of Zope 3 technologies through Five (see http://codespeak.net/z3/five/) For more information on what is new in this release, see the CHANGES.txt files for the release: http://www.zope.org/Products/Zope/2.8.5/CHANGES.txt See also: http://www.zope.org/Wikis/DevSite/Projects/Zope2.8/OverView Please bring all the bugs you have found to the Zope bugtracker: http://collector.zope.org/Zope":http://collector.zope.org/Zope For more information on the available Zope releases, guidance for selecting the right distribution and installation instructions, please see: http://www.plope.com/Books/2_7Edition/InstallingZope.stx Please also keep in mind that Zope 2.8.5 requires Python 2.3.5. Zope 2.8.5 is not certified for any Python 2.4.x versions. So using Python 2.4 is neither recommended nor supported and any related questions or problems are likely to be ignored until 2.4 is an officially supported Python version for Zope. -- Andreas Jung (andreas at zopyx dot com)

Hi List, I downloaded zsyncer-0.7.0 and am having problems. Its not working for me and it no longer displays prompts for destination password and user name when clicking its <edit> tab. Anyone else seeing this? More importantly, as a fall-back is there a version (0.6.1?) others recommend? All best, David

zope-2.9 r40780 make install doesn't finish, files missing from bin
by Jeff Kowalczyk 18 Dec '05

18 Dec '05

I'm having some trouble with the 'make install' stage of Zope-2.9 svn. Using python-2.4.2 on Gentoo linux. Zope-2.9.0b1 installed fine, but I needed the fix for get_transaction() ASAP. URL: svn://svn.zope.org/repos/main/Zope/branches/2.9 Revision: 40780 # ./configure --prefix=/usr/lib/zope-2.9.0 # make # make install (...) copying lib/python/zope/app/recorder/zope.app.recorder-configure.zcml -> /usr/lib/zope-2.9.0/zopeskel/etc/package-includes copying lib/python/zope/app/pluggableauth/zope.app.pluggableauth-configure.zcml -> /usr/lib/zope-2.9.0/zopeskel/etc/package-includes copying lib/python/zope/app/securitypolicy/securitypolicy-meta.zcml -> /usr/lib/zope-2.9.0/zopeskel/etc/package-includes copying lib/python/zope/testbrowser/testbrowser-ftesting.zcml -> /usr/lib/zope-2.9.0/zopeskel/etc/package-includes copying lib/python/zope/formlib/formlib-configure.zcml -> /usr/lib/zope-2.9.0/zopeskel/etc/package-includes copying lib/python/zope/app/securitypolicy/securitypolicy.zcml -> /usr/lib/zope-2.9.0/zopeskel/etc [ -f /usr/lib/zope-2.9.0/bin/python ] || ln -sfn "/usr/bin/python" /usr/lib/zope-2.9.0/bin/python Zope binaries installed successfully. Now run '/usr/lib/zope-2.9.0/bin/mkzopeinstance.py' This leaves (most visibly) many missing files in /usr/lib/zope-2.9.0/bin/. Only the 'python' symlink, and 'zconfig zconfig_schema2html zdctl.py zdrun.py' are installed there. Other files may be missing if they came afterwards, I don't have information on that. Is this line indicating a terminating error in make install? [ -f /usr/lib/zope-2.9.0/bin/python ] || ln -sfn "/usr/bin/python" /usr/lib/zope-2.9.0/bin/python Subsequent runs don't resume installing the remaining files: # make install "/usr/bin/python" "/home/jtk/software/svn/Zope/setup.py" \ build_ext -i \ install --home="/usr/lib/zope-2.9.0" running build_ext running build_headers running install running build running build_py running build_scripts running install_lib running install_headers running install_scripts changing mode of /usr/lib/zope-2.9.0/bin/zconfig to 755 changing mode of /usr/lib/zope-2.9.0/bin/zconfig_schema2html to 755 changing mode of /usr/lib/zope-2.9.0/bin/zdctl.py to 755 changing mode of /usr/lib/zope-2.9.0/bin/zdrun.py to 755 running install_data [ -f /usr/lib/zope-2.9.0/bin/python ] || ln -sfn "/usr/bin/python" /usr/lib/zope-2.9.0/bin/python Zope binaries installed successfully. Now run '/usr/lib/zope-2.9.0/bin/mkzopeinstance.py' Thanks for any insight on the issue. I don't think I want to run Zope in-place from the working copy.

zopectl or runzope just won't start zope
by Qass 18 Dec '05

18 Dec '05

Hi: I'm new to zope and yesterday installed zope 2.8.4 on a linux system running python 2.3.5 Having followed installation instructions I got to the point of 'zopectl start' and got the following error message while trying both 'runzope' and 'zopectl'. I've tried installing different versions of Zope and get the same error (error absent with Zope 3). At one point, Zope did start (I moved it to a different port) but when I tried installing Plone in the Products directory of the zope instance, the 'Plone Site' did not show up in the drop down menu on the right hand side of the ZMI. Which is why I decided to reinstall and have been getting errors since. I haven't messed around with the Python installation at all. In this latest install I ran 'make instance' intead of 'make install' just to see if I would get the same error as I did yesterday when I had an instance of Zope running and I did. Any help in trying to fix this would be highly appreciated. I've tried changing PYTHONPATH in the zopectl file but that just leads to more and more errors. Traceback (most recent call last): File "/blah//Zope-2.8.4-final/lib/python/Zope2/Startup/run.py", line 56, in ? run() File "/blah/Zope-2.8.4-final/lib/python/Zope2/Startup/run.py", line 17, in run import Zope2.Startup File "/blah/Zope-2.8.4-final/lib/python/Zope2/__init__.py", line 60, in ? from Zope2.Startup.run import configure File "/network/share/home/sra/Zope-2.8.4-final/lib/python/Zope2/Startup/__init__.py", line 24, in ? import ZConfig File "/blah/Zope-2.8.4-final/lib/python/ZConfig/__init__.py", line 21, in ? from ZConfig.loader import loadConfig, loadConfigFile File "/blah/Zope-2.8.4-final/lib/python/ZConfig/loader.py", line 23, in ? import ZConfig.datatypes File "/blah/Zope-2.8.4-final/lib/python/ZConfig/datatypes.py", line 19, in ? import datetime File "/blah/Zope-2.8.4-final/lib/python/DateTime/__init__.py", line 13, in ? from DateTime import DateTime File "/blah/Zope-2.8.4-final/lib/python/DateTime/DateTime.py", line 21, in ? from datetime import datetime File "/blah/Zope-2.8.4-final/lib/python/DateTime/DateTime.py", line 21, in ? from datetime import datetime ImportError: cannot import name datetime Thank you very much for your help.

Apparently my <zope-instance>bin/zopectl stop / restart sequence was not working on my remote (zettai) instance.

using tal macros in PloneArticle query
by Stefan Kueppers 16 Dec '05

16 Dec '05

Hi all, I am trying to use tal and metal inside of a PloneArticle instance and can not get it to work. Should this not be possible? I am aware that kupu needs to be switched to not strip customg tags on edit and that there are settings which enable or disble content types in the article instance. I did enable the text/python-source type in the PloneArticle settings, but this still seems to not work. Anyone knows what I might be doing wrong? Many Thanks!!
