Evaluate the queryset first by calling list() on it: tcs = list(TestCase.objects.filter(case_id__in = [1123, 1124, 1125])) And you don't need to use setattr if you already have the name you need to set, you can just set it directly: tc.selected_param = [] setattr is mostly useful if the name of the attribute you want to set is itself in a variable. -- DR. -- You received this message because you are subscribed to the Google Groups "Django users" group.
