You can overwrite the save() method and do the checks there. But you can't do much, except to raise an exception. If a user uses the admin interface, he might only see 'Internal server error' in his browser. But I don't think you need introspection. Since you know the object at coding time, you don't need to check what kind of objects you are dealing with.
