I would look at 'ZTopics.Topic._contentsSet()' to see what it is trying to do with the catalog. I would log also log this as a PTK issue: http://www.zope.org/Products/PTK/Tracker rather than in the Collector (I don't believe it is a Zope issue, per se).

Place a DTML method(!) "index_html" high in your Zope hierarchy with the following code: <dtml-var index.html> >From then on, you can happily create "index.html" below that point in the hierarchy. It will be used as the default folder view. In fact, "index_html" is used but that redirects to "index.html". Dieter

paul_s_johnson(a)urscorp.com writes: > ... passing parameters to Z SQL methods ... This is an FAQ. You already know the searchable list archive at NIP? Z SQL methods do *NOT* take parameters from the DTML namespace. They only look at "REQUEST". You have two options: 1. put your parameters into the REQUEST object: <dtml-call "REQUEST.set('myparam', myparam_value)"> .... 2. call the Z SQL method with explicit parameters: <dtml-in "myMethod(myparam= myparam_value, ....)"> Dieter

"aq_parent". It is an attribute, not a method. Dieter

In fact, I do not understand what your problem is: you mention an external method, a script and a link. It is unclear (for me) what the relation between these entities is. What is the difficulty to generate the above link? Do you want to do it in DTML and you have problems to integrate the '"'? In this chase, use "\042", the octal excape for '"'. Dieter

Re: [Zope] ZCatalog and dates

Zope uses "DateTime" object to hold date and time. When you render such an object, you see just the date portion. But there is a time portion as well. It is quite difficult to make a query, where the dates match exactly. You will probably need range queries to search for dates (--> ZopeBook, Advances ZCatalog HowTo). Dieter
