Re: Using variables as keywords in QuerySet

[Hector Garcia]

Also note the usage of __exact can be discarded in favor of the
'exact' form of keyword, as it is encouraged here:

http://groups.google.com/group/django-users/browse_thread/thread/04b3ca49dc3f9c18/bdfb4849c0e885da?lnk=raot

So,

MyModel.objects.filter(**{a+'__contains': 'foo', b: 'bar';})

Or, more concisely as:

MyModel.objects.filter(**{a+'__contains':'foo', b+'__exact':'bar';})
