Basic Template question : 'truthiness'
by Mark Gibson 11 Jun '06

11 Jun '06

I thought I knew how this stuff worked, but this has gotten me banging my head against a wall. I'm trying to evaluate a condition expression, and I'm not getting what I expect when using path, and I get a different result when using python. The following expressions results=<span tal:content="results" /><br /> dosearch=<span tal:content="request/dosearch | string:NO SEARCH" /><br /> querytpe=<span tal:content="request/querytype | string:NO QUERYTYPE" /><br />  <div tal:condition="python:len(results) or request.get('dosearch',None) or request.get('querytype',None)">TRUE IN PYTHON</div> <-- This doesn't evaluate to true --> <div tal:condition="results | request/dosearch | request/querytype | nothing">THIS DOESN'T SHOW UP</div> ---- Produces: results=[] dosearch=NO SEARCH querytpe=mps TRUE IN PYTHON As you can see, the second expression doesn't evaluate to True. Can someone explain the subtleties I seem to be missing? Thanks, Mark

zwiki connection error
by Josh Stephenson 11 Jun '06

11 Jun '06

Hey all, Recently, ZWiki stopped working on my zope 2.9.2 intel mac os x 10.4 box (python 2.4.2). It was working fine until sometime yesterday, when I could no longer access my wiki using the address http://<my ip>:8080/mywiki This is strange because zope is running, I can get into the zmi, create objects from any other product, view public pages running on the zope server, but whenever I try to view my wiki, I get: Unable to connect Firefox can't establish a connection to the server at <my ip>:8080. Again, just to be clear, I can view any other zope-hosted page using the same ip and port. Any thoughts? -josh

Re: [Zope] prefix attribute in dtml-in

You can use "names" to see the actual column names: <dtml-var expr="getConsulting().names"> (or perhaps it is .names(), this code is untested) Gabriel Genellina Softlab SRL ___________________________________________________________ 1GB gratis, Antivirus y Antispam Correo Yahoo!, el mejor correo web del mundo http://correo.yahoo.com.ar

What's new in this release? The 1.6.1 release represents a pure bug fix/maintenance release without feature additions. It provides the basis for the upcoming Plone 2.5 release. Where do I get it? Download it from http://www.zope.org/Products/CMF/CMF-1.6.1 Points of interest include: - Windows ZIP file: http://www.zope.org/Products/CMF/CMF-1.6.1/CMF-1.6.1.zip - Unix tar/gzip archive: http://www.zope.org/Products/CMF/CMF-1.6.1/CMF-1.6.1.tar.gz - Release notes: http://www.zope.org/Products/CMF/CMF-1.6.1/README.txt - Change history: http://www.zope.org/Products/CMF/CMF-1.6.1/CHANGES.txt - Installation instructions: http://www.zope.org/Products/CMF/CMF-1.6.1/INSTALL.txt - CMF Release Roadmap: http://www.zope.org/Products/CMF/docs/roadmap Where do I go to learn more?

prefix attribute in dtml-in
by Sam Boggess 08 Jun '06

08 Jun '06

Using Zope 2.8, I have two nested <dtml-in> tags that each loop through the results of different SQL methods. I'm trying to use the prefix attribute to differentiate the two, but I can't get it to work. Does anyone have any thoughts? <dtml-in expr="getConsulting()" prefix="topic"> <fieldset> <legend><dtml-var expr="sequence_var_fulltitle"> Sub Topics</legend> <dtml-in expr="getConsultingSub()" prefix="subtopic"> <fieldset> <legend>Topic <dtml-var subtopic_displayorder>: <dtml-var subtopic_menutitle></legend> </fieldset> </dtml-in> </fieldset> </dtml-in>

dtml forwarding request
by Alric Aneron 08 Jun '06

08 Jun '06

Hello, Is there a way in Zope to forward a request from one page to another. When I say "forward" a request, I want to retain all the GET and POST request parameters. So similar to <dtml-call expr="RESPONSE.redirect('...')"> but response.redirect loses all the request parameters. I've been looking around and couldn't find it. Any ideas? Thanks in advance! --------------------------------- Yahoo! Groups gets better. Check out the new email design. Plus theres much more to come.

RE: [Zope] REQUEST within a property() getter/setter

I was afraid of this ... :( Back to using get_request() then!

No. Python's low level attribute access methods ("__getattribute__", "__getattr__", "__setattr__", property setter/getter) are below the reach of acquisition. Their "self" is not acquisition wrapped. That's why your "self.REQUEST" is "Acquisition.Acquired" (rather then the acquire object). -- Dieter

installing zope2.9.3 attempt
by Thomas Bennett 08 Jun '06

08 Jun '06

I'll have to say, this is the first Zope that I've had a problem with the install since 1998. The last successful version I installed was 2.92. RedHat Linux 7.3 Python 2.4.3 I've looked at the Troubleshooting info in the INSTALL.txt file and my Makefile for Python 2.4.3 shows CC= gcc -pthread CXX= c++ -pthread and it was a "vanilla build". I've searched zope.org and google and haven't found anything relative to this problem except that a change from 2.9.2 to 2.9.3 fixed a "make install" problem. It looks like to me that not finding a zcml configuration file it quits. Any ideas how I can fix this?

Export format documentation
by Sébastien VINOT 08 Jun '06

08 Jun '06

Hello, I have an export file of objects (that come from a Plone 2.0.5 instance). Unfortunately, the products are not compatible with a newer Plone version. I'm building a new version of this product (but it will be quite different from the initial one). I'm wondering if it is possible to load datas for a zexp file without the old product and then build new instances of my new product. That is why I'd like to know if there is a good documentation concerning the internal structure of zexp files. Thanks in advance Sebastien
