If you just want to return back brains objects, the following worked for me
in the debugger:
types = ['ItemType1', 'ItemType2']
catalog = root.portal.portal_catalog
res = []
for t in types:
res.append(catalog(Type=t))
Hope this helps,
Andrew

Subject: [Zope-CMF] Help on catalog query
Hello,
I want to create some dynamic portal_catalog querys based on different
portal types ...
I want to have a query that fetches all the 'event_like' objects (because
they have the start_date property) and all other properties from there Date
property ...
It's no problem making one query ..
But how do I make a loop that fetches some results and then adds the
results to a variabel to I can return only on catalog result ?
I have tried with:
result = ''
for type in types:
res = catalog.searchResults(some parameters)
result = result + res
but that gave me an error (something with bad operator '+') ..
Then I tried with:
result = []
for type in types:
res = catalog.searchResults(some parameters)
result.append(res)
But that didn't return anything useful ..
Isn't there some way to join results from querys ?
TIA,
Gitte Wange
