You can access the model instance via form.instance. To get access to the request, you'll need to pass it in to the form somehow. The best way is probably to override the form's __init__ method to add a request parameter and save it as self.request - you can then pick it up in the clean method. However it's not clear why you need to access the session - there's no need to do if you just want to do model queries. -- DR. --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Django users" group.
