Hi,
Sorry for my late reply ...
Normally ... wouldn't you call catalog.searchResults for getting the =
brains objects ?
TIA,

If you just want to return back brains objects, the following worked =
for me in the debugger:
types =3D ['ItemType1', 'ItemType2']
catalog =3D root.portal.portal_catalog
res =3D []
for t in types:
res.append(catalog(Type=3Dt))
Hope this helps,
Andrew

Hello,=20
I want to create some dynamic portal_catalog querys based on =
different portal types ...=20
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 ...=20
It's no problem making one query ..=20
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 =3D ''
for type in types:
res =3D catalog.searchResults(some parameters)
result =3D result + res
but that gave me an error (something with bad operator '+') ..=20
Then I tried with:
result =3D []
for type in types:
res =3D catalog.searchResults(some parameters)
result.append(res)
But that didn't return anything useful ..=20
Isn't there some way to join results from querys ?
TIA,
Gitte Wange
