anti-join query in Django

Is there a recommended approach to anti-join queries? Here's the query I'm having an issue with: Branch.objects.filter(branchgroup__isnull=True)[:1] where branchgroup is a ManytoMany relationship to another model. I want to get a set of Branch objects that aren't mapped to any BranchGroups.

Hi, is there a way to check in bulk for record existence and get back a map of results similar to what's returned by in_bulk(). In my case, I need to look up records by a unique field which is not the primary key and I don't want object instances back, just true or false. Thanks Dmitry --
