I'm starting to experiment with ZCatalogs as a way to organize and access some content on my web site. I've created a ZCatalog and had it index some key attributes of some ZClass instances that I have created. Currently my catalog has 4 entries. Elsewhere I have some code which is attempting to extract ZClasses with specific attributes. In my particular case my ZClasses are news articles and each article has a 'section' attribute which indicates where the article should be viewed. I have a DTMLMethod which looks like this: <dtml-in "ArticleIndex(meta_type='Article', section='Restaurant Review', publicationDate=_['publicationDate'])"> <dtml-return "ArticleIndex.getpath(data_record_id_)"> </dtml-in> This method is implemented in an "issue" object which, among other things, defines a property called "publicationDate". There is only one 'Article' which has a section of 'Restaurant Review'. As such, my assumption was that this method would return the url of the article with a section property of 'Restaurant Review'. Unfortunately this isn't the case. Upon further debugging, I find that this loop is iterating over *all* items in the catalog rather than finding the one entry with the proper section value. My obvious question is why? From what I've read, my statement should only return a collection of objects who have a meta_type of Article, a section value of 'Restaurant Review' and a publication date equal to the publication date of my issue. Can someone explain why my request to the catalog is returning objects which don't meet all the requirements? Thanks. James W.
