In general it's a bit tricky. Doing it like this and feeding this new_data to manipulator will validate and save everything including uploaded files. But since Django doesn't automatically remove associated files on update you'll get lost files sitting forever in your upload dir whenever you upload new file. This should be resolved manually depending on what your app is supposed to do in this case.

However due to a bug (http://code.djangoproject.com/ticket/555) auto_now_add fields are saved successfully but not populated with the new time after save. This causes your bug because manipulator actualy saves the object twice: first time for the object itself and second time doing save_*_file which calls object's save(). Ad this second save() tries to update auto_now_add field with empty value that still lives in it. To work this around you can write override object's save() and select new saved time explicitely into the field as described in first comment in the ticket. --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Django users" group.
