Simon, Ran in the same issue as you. I filed documentation ticket #6690 to document a clean way to dynamically create ModelForm instances. The ticket got closed because the runtime creation of forms "isn't common enough"...
See also the thread "ModelForm: Dynamically change model and fields" on the django-users list from some other folks struggling with this... http://groups.google.com/group/django-users/browse_thread/thread/7ef532fa113e78d9/e8be364504c8dcb8 Regards, Johan On Apr 7, 2:05 pm, Simon Willison <[EMAIL PROTECTED]> wrote: > form_for_model is marked as deprecated but ModelForm does not appear > to be a full replacement for it.
