28 Feb '04

Let 'pdate' be a python datetime object. I can do this: 'tal:attribute="value python:now"' However if I try to print out an attribute of 'now', like 'tal:attributes="value python:pdate.year"', I get a login prompt and the page fails with the following message: [...] * Module Products.PageTemplates.ZRPythonExpr, line 47, in __call__ __traceback_info__: pdate.year * Module Python expression "pdate.year", line 1, in <expression> Unauthorized: You are not allowed to access 'year' in this context Anyone know how to avoid this? Regards, Sandor

Virtual Host Monster generates a monsterous URL!
by Patrick Kirk 27 Feb '04

27 Feb '04

A quick visit to www.enterprise-hr.com works but generates this huge URL: http://64.5.48.153:8081/VirtualHostBase/http/enterprise-hr.com:80/www/Virtu… The httpd.conf I suggested to him was <VirtualHost 64.5.48.153> ServerName www.enterprise-hr.com DocumentRoot /websites/enterpri/zope RewriteEngine on RewriteRule ^/(.*) http://64.5.48.153:8081/VirtualHostBase/http/enterprise-hr.com:80/www/Virtu… </VirtualHost> The VHM documentation is kinda dense so does anyone see why I'm getting the huge URLs? -- Best regards, Patrick Kirk Mobile: 07876 560 646

CMF Filesystem Directory View
by Poor Yorick 27 Feb '04

27 Feb '04

Hello, if the answer to my question is already available somewhere, please let me know... I looked around quite a bit. I am trying to add a filesystem directory view (Zope 2.7, Plone 2.0), and can't figure out how to add new directories to the list of directories available to choose from. Could anyone clue me in?

httpd.conf Zope on Apache-based ISP
by Patrick Kirk 27 Feb '04

27 Feb '04

Hi all, I'm putting a Zope site on an Apache based hosting service. They've asked me to suggest the virtual hosts section of httpd.conf and for me to run Zope on 8081 to avoid conflicts. The files are in a folder called /websites/patrkirk/public_html/ with a cgi folder called /websites/patrkirk/public_html/cgi_bin/ It seems that there are very many ways of doing this and I'm at a loss how to choose the right way. Can anyone suggest an authoritative URL that simply allows zope to run on some high number port with Apache serving up its pages? I have no access to Apache so extensive re-writes of httpd.conf are unlikely to be accepted by the ISP. This is my first draft. # Zope redirection <IfModule mod_rewrite.c> RewriteEngine on RewriteCond %{HTTP:Authorization} ^(.*) RewriteRule ^/Zope/(.*) /var/lib/zope/cgi-bin/default/$1 [t=application/x-httpd-cgi,l] </IfModule> <VirtualHost 195.224.53.44> ServerName www.enterprise-hr.com DocumentRoot /websites/patrkirk/public_html/zope RewriteEngine on RewriteRule ^/(.*) /var/lib/zope/cgi-bin/default/$1 [t=application/x-httpd-cgi,l] </VirtualHost> Does this look right and if not can someone please tell me what I need to do? Thanks in advance. -- Best regards, Patrick Kirk Mobile: 07876 560 646

Overview of changes in 2.7.0 ??
by Max M 27 Feb '04

27 Feb '04

I am running 2.6.* and is trying out this newfangled Zope 2.7.0 thing. I have no problem setting it up, getting it running etc. But is there any good documentation on what the changes are, and what they mean. The closest I could come to something readable was: http://www.mechanicalcat.net/richard/log/Python/What_s_new_in_Zope_2_7_0 But that is a bit short on information. regards Max M

Caching Catalog results for performance
by Heimo Laukkanen 26 Feb '04

26 Feb '04

Hi all, I am working on a portal where we want to cache some catalog queries per person for some time, from few seconds to few minutes - since the data is something that does not need to be updated every single pageload, but can be cached for seconds - sometimes even for multiple minutes per user. What we have been thinking so har is this: - Cached data will be stored in ram in Temporary folder in simple object that will store data in it's attribute. Memory is not an issue for now, and if it will become - cached data will be stored in ZODB, rather than kept all the time in the memory. - Since brains are unpickleable we will create a dictionary from the brain by getting schema from the Catalog and then just getting each metadatafield from the brain Has anyone else done similar or thought about doing it? -- -huima

cacheing zope
by robert rottermann 26 Feb '04

26 Feb '04

Hello, I am looking for info on how to use * RAM Cache Manager* *** Accelerated HTTP Cache Manager* ** I am using Zope 2.7 How do I interpret the numbers in the Statistics? I have a Ram Chache and get rather lot of misses. How can I improve the hits ? What I want to improve is a plone site. Much of the time (as I can see from a profiler) is spent in creating the news list. However this list is nearly static (only every couple of days any changes). How can I improve that ? thanks for your info Robert

server_capabilities - resolution
by Poor Yorick 26 Feb '04

26 Feb '04

So that others may google this info: I recently kept getting an error in a zope product (ZWarehouse) about a missing attribute: "server_capabilities". I resolved it by copying the MySQL headers and include files from the source package into directories in /usr/lib and /usr/include and running ldconfig Poor Yorick zope(a)pooryorick.org
