This is something that is being addressed in newforms-admin. It is
necessary for django.contrib.admin and
django.views.generic.create_update (#3639 - newforms patch) to have
some helper function to dynamically create a ModelForm since the model
is not known until runtime. I think what you are trying to get at is
something similar to a FormSet found in the newforms-admin branch.
You might want to check it out.
