I use this. Maybe there is a better solution: Person.objects.filter(burse_set__isnull=False) PS: You can get Burse from Person without 'get_all_related_objects()', too. This method is just to improve/decrease performanace. --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Django users" group.
