How to get Entrys from a catalog by date boundaries
Hi, I've tried to select all entrys from a catalog by defining the date boundaries(Python script). Looks like this: id=context.getId() return context.cata( {'content' : id, 'date': [datestart, dateend], 'date_usage' : 'range:min:max', } ) cata = my catalog,datestart =start date(date-string),dateend=end date When I send my request, the only things I get back are some <MYBRAnI instance at #123848>-tags. For the beginning i would just like to get the ids of the items in the boundaries. How can i achieve that? Please help !! Sebastian

If you have id set up as catalog metadata, then those objects will each have an id attribute which does what you want.

Thats what you get back from catalog queries. Each brain is a small object that has all the meta-data you have indexed in the catalog as properties. It's done like this to enable queries to be "lazy". You don't actually need to read in the data until it's accessed, which is a great performance boost. You use the brain as if it were a dictionary, and the result is a list of brains. So you go for brain in result: if brain['id'] == 'foo': context.barf() or something of that ilk.
