A better way might be to use model inheritance (multitable). The parent model would just include the field you want to be unique, and the subclassed models would include their own fields. You should be able to set unique=True on that one field in the parent model, and it should work. -- DR. --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Django users" group.
