ZCatalog indexes and unit testing
by Eric Bréhault 26 Jul '07

26 Jul '07

Hello, I have created a ZCatalog object where I declare the following index: self.addIndex('featureType','FieldIndex') which works fine in my application But when I run it in my unit tests, I get the following error: self.addIndex('featureType','FieldIndex') File "/opt/Plone3/lib/python/Products/ZCatalog/ZCatalog.py", line 971, in addIndex raise ValueError, "Index of type %s not found" % type ValueError: Index of type FieldIndex not found I am using the unitest package, I have declare a lot of stuff in configurationSetUp, but something is probably missing: (is there something to import from PluginIndexes ?) import unittest from zope.component.testing import setUp, tearDown from zope.configuration.xmlconfig import XMLConfig from zope.testing import doctest from zope.testing.doctestunit import DocFileSuite def configurationSetUp(self): setUp() import Products.zgeo import zope.component import zope.annotation import zope.app.publisher.browser import Products.Five import Products.Archetypes import Products.CMFCore import Products.GenericSetup XMLConfig('meta.zcml', zope.component)() XMLConfig('meta.zcml', zope.app.publisher.browser)() XMLConfig('meta.zcml', Products.Five)() XMLConfig('meta.zcml', Products.GenericSetup)() XMLConfig('meta.zcml', Products.CMFCore)() XMLConfig('configure.zcml', zope.annotation)() XMLConfig('configure.zcml', Products.Five)() XMLConfig('configure.zcml', Products.GenericSetup)() XMLConfig('configure.zcml', Products.Archetypes)() XMLConfig('configure.zcml', Products.zgeo)() Thanks, Eric

ANN: eGenix EuroPython 2007 Presentations & Videos

________________________________________________________________________ eGenix EuroPython 2007 Presentations & Videos ________________________________________________________________________ eGenix is pleased to announce the immediate availability of PDF and Flash video versions of the presentations we gave at this years EuroPython 2007 conference in Vilnius. This announcement is also available on our web-site for online reading: http://www.egenix.com/company/news/EuroPython-2007-Presentations.html ________________________________________________________________________ INTRODUCTION The EuroPython Conference is the one of the premier conferences for Python & Zope users and developers. This year it was being held from the 9th to 11th July in Vilnius, Lithuania. eGenix was one of the founding members of the EuroPython conference team and played a major role in organizing the first EuroPython conference in the year 2002. Since then we have attended every EuroPython conference to meet up face-to-face with the people from the Python & Zope communities and have given regular talks at these conferences. ________________________________________________________________________ TALKS AT EUROPYTHON 2007 We gave the following two talks at the conference. The presentations are available for viewing and download from our Presentations and Talks section: http://www.egenix.com/library/presentations/ As special feature, we have added talk videos in addition to providing the slide PDFs. You can view the talks online if you have the Adobe Flash Player 8 or later installed. * Parsing Languages with mxTextTools mxTextTools comes with a high performance Tagging Engine for text and Unicode data which can be used to tokenize and parse languages. The resulting abstract syntax tree can then be hooked up to a generator to build a complete and fast compiler in pure Python. The talk gives a short introduction to the way the mxTextTools Tagging Engine works and how it can be used to build compilers. mxTextTools is an eGenix Open Source product available as part of the eGenix mx Base Distribution. * An introduction to working with relational databases from Zope Although Zope has been around for quite a while, it continues to find new users particularly amongst non-programmers who are looking for a way to work with existing data which is usually in some relational database (PostgreSQL, MySQL, MS SQL, Oracle, DB2, etc.). One of the reasons for this is that Zope provides an extremely powerful, yet secure, through-the-web programming environment. The presentation is directed towards new users and will provide a brief introduction by example into the Zope way of doing things. At the same time it highlights how working within Zope is automatic training in good programming methodology: data management is delegated to ZSQL methods, PythonScripts act as controllers and Zope Page Templates provide the views. Together they encourage modularity and reusability. The sample application and database are available for download.

Telling Psycopgda2 to return unicode strings
by Andreas Elvers 26 Jul '07

26 Jul '07

Hi, I don't know if this is common knowledge, but I couldn't find anything about it on the web. So I hacked it myself. When querying a Postgresql database using unicode in Zope 2.10 via ZPsycopgda2, the adapter will return unicode data in plain strings. To force unicode strings to be returned go to your Products folder and create a directory like ZPsycopgda2SetUnicode. In this directory put an __init__.py file containing this code: import psycopg2 import psycopg2.extensions psycopg2.extensions.register_type(psycopg2.extensions.UNICODE) After this restart Zope. ZPsycopgda2 should now return unicode strings. - Andreas

tal:content="structure... and unicode... How to get it work in Zope 2.10.4 ?
by Andreas Elvers 25 Jul '07

25 Jul '07

Hi, I'm having a hard time with page templates using unicode. Here is a simple example: - create a page template called dejavu Encoding is utf-8. Check also your browser character encoding to be set to unicode as well. - put this into the page template.: IMPORTANT: Since this discussion is in ASCII, I can't write the correct deja vu string here. When testing please use the correct spelling. See http://en.wikipedia.org/wiki/Dejavu :-) <span tal:replace="structure python:u'deja vu'"></span> When I test this template i will not get deja vu but instead garbled characters for e and a. Why is this ? Greetings, - Andreas

Pickle error and Zeo setup
by Sudesh soni 24 Jul '07

24 Jul '07

BlankHi, I am trying to update the 'SiteRootBase' in the secure.xml file and do import in zope , but I get error as shown in the screenshot. I did same with secure.zexp and another error : cannot convert long int.... , i face when i import that file. Why zope2.8.5 does not allow importing secure file after update. I need to change /set the 'SiteRootBase' , is there any other way to achieve that? ------------------------------------------------------------------------------------------------------------------------ Secondly I am setting up a ZEO server and I move the data.fs to ZEO storage location. Q1. The data.fs I moved has SiteRootBase set to one of the zeo client URL. I have another zeoclient which runs on a different URL/subdomain. As a result I see the same secure on another zeoclient ZMI, but as the SiteRootBase is set to the primary zeo client, Will this affect the request that will be diverted to the second zeo client ? Q2. What settings I need to do to set up 2 zeo clients as I have one ZEO server running so that requests are properly served. I am using mirroring feature from primary zeo client to divert request to another zeo client randomly. Any help is appreciated in advance. Regards SuSon

ZODB FileStorage inspection tool: treenalyser
by Pelletier Vincent 24 Jul '07

24 Jul '07

Hi. I created a ZODB FileStorage inspection tool which originaly derived from netspace.py (as of zope 2.8.8). I was especially interested in actual object content, so this script offers the possibility to hex dump objects, and exports some more knobs (recursion depth, subtree selection, more verbosity levels) as parameters and adds some features (python-friendly path rendering, recursion depth error handled). I removed the pack-before-use feature as I consider it out of place (packing considered a read-only operation doesn't mean it should be made available in every tool doing read-only operations...). You can get it from the following SVN repository: https://svn.erp5.org/public/erp5/trunk/utils/treenalyser.py ViewVC available at: http://svn.erp5.org/erp5/trunk/utils/treenalyser.py -- Vincent Pelletier PS: Yeah, its name is bad... Feel free to propose any better naming.

folders show with firefox but not IE7
by Tim Nash 23 Jul '07

23 Jul '07

Anyone experiencing weird behavior with IE 7? I was creating folders into a folder that had exiting folders and the new folders wouldn't show up (old ones did show)until I did a paste of a different folder. Then all the folders showed up. I removed the user folder and a catalog from that folder and still saw the same problem. Then I switched to firefox and everything was back to normal. All the folders appeared upon creation. Any thoughts? Tim IE7 firefox 1.5 zope 2.9
