This is probably outside the scope of what can be achieved via formfield_for_foreignkey. However it would be possible by defining a custom form and overriding the __init__ method. After calling super(), you can then modify the queryset of the FK field - you would have access to the current instance via self.instance. -- DR. --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Django users" group.
