tal:replace and Traverse
by Nancy Donnelly 03 Nov '06

Hi; I can do this: <div tal:replace="template/comment"></div> and fetch my variable from the document. However, I want to be able to fetch it from another document, like this: <div tal:replace="Essential_Documentation/Rosenthal_Interview_frame.pt/template/comment"></div> But that syntax doesn't work. How do I do it? TIA, Nancy

Preserve HTML tags, such as <P>, not into < P> in python code for Zope 2.9.4
by Zhi-Wei Lu 02 Nov '06

02 Nov '06

Hi Zope Gurus, During the server upgrade from Zope 2.7.4 to 2.9.4, I encountered a problem for the following simple python script: text = container.research[name].research_description_html text = str(text) return text[0:400] + '...' This code suppose to return the first 400 characters of an abstract, the abstract is in HTML. However, this will return HTML tags such as <P> into <P&> in the calling routine. (Zope 2.7.4 doesn't do that) But if I simply have the following code: text = container.research[name].research_description_html return text It preserves the HTML tages such as <P> for zope 2.9.4. I will be very glad to receive tips fix my problem. I posted an email a few weeks ago, I didn't quite grasp the problem (confused) then. Thank you very much for your help.

Mime type for PDB files
by Alan 02 Nov '06

02 Nov '06

Hi List! I have some lines in a ZPT file creating a link to PDB files in a LocalFS folder: <span tal:repeat="item python: options.get('pdbsw','null')"> <tr><td> <a tal:attributes="href python: container.JOBS.absolute_url()+'/'+item+'.pdb'" tal:content="python: item+'.pdb'">get file</a> </td><td> </span> It works fine expect for one thing. When clicking at the link, my browser (Safari), thinks my PDB file has mime type text. Is it possible to define the mime type (chemical/x-pdb) for my linked files in Zope? I would thank any attention in advance.

newbie root addressing questions
by Terry Brown 02 Nov '06

02 Nov '06

I'm buidling a site in /site/collected on a Zope system. Using ZPT rather than DTML So every page starts with <html metal:use-macro="root/site/collected/tmpl/basepage/macros/page"> also, for the time being, the site's at someurl.com/collected/, but in future might be someurl.com/ so pages include things like <link href="/collected/collected.css" rel="stylesheet" type="text/css"/> so I'm wondering 1) how I can make the site relocateable on the Zope system, i.e. each file has 'root/site/collected' in the initial macro call, can that be avoided, and 2) how can pages refer to their site's root when that is currently /collected/ but might later become / ? I found some discussion of DTML approaches, but I'm hoping for something purely ZPT. For (2) the main problem seems to be that if I put the root path (/collected/ or /) in /site/collected/rootpath it's hard to find from /site/collected/gallery/ or /site/collected/gallery/page1/ or some other sub-sub-location. Thanks,

External Method = Slow; Shell Script = Fast
by Edward Pollard 01 Nov '06

01 Nov '06

Hello, I've got an external method that does some pretty complicated stuff. Basically it takes two XML files - one defines constraints, the other variables - and the script finds a solution using the variables that satisfies the constraints. At the command line (or executed via an external method that calls a shell script) execution is 2 seconds. As an external method execution is 15-20 seconds with the same input. Can anyone offer tips or strategies to improve performance? It would be obnoxious to have to encode objects for passing to a shell script. --- Edward J.

[Zope] Zope 2.6.4 -> 2.10.0 Migration (PageTemplates, Unicode, etc.)
by Brian Brinegar 01 Nov '06

01 Nov '06

So... We decided to move from Zope 2.6.4 to something newer (currently targetting Zope 2.10.0). I immediately found that none of our PageTemplates work we get an error on PageTemplates/Expressions.py line 92 that call_with_ns is not defined. ob = call_with_ns(ob, ns, 2) Changing it as follows fixes the problem, I think this is a bug. ob = ZRPythonExpr.call_with_ns(ob, ns, 2) Next... we have lots of PageTemplates which raise the following exception: Module zope.pagetemplate.pagetemplate, line 118, in pt_render Module StringIO, line 271, in getvalue UnicodeDecodeError: 'ascii' codec can't decode byte 0xb9 in position 93: ordinal not in range(128) I suspect there are non-ascii characters in the file, but I'm not sure how to fix this, or how I would know what to replace it with. Is there a way to turn off Unicode support? Any other issues I might run into during this upgrade? Should we move to an older version (2.8? 2.9?) first and then onto 2.10?
