I think the easiest solution would be to not use modelchoicefield
here, and set the choices manually like Rajesh suggested.
choices=[(o._get_pk_val(),str(o) for o in qs]
for i in requested_forms:
form=CustomMediaForm(data,auto_id="some_generated_id")
form.fields['somefield'].choices = choices
Unless you're CustomMediaForm is from a generator like
form_for_instance, you'd probably be better off modifying form
specific things like choices after instantiation. For example if you
had 10 instanaces of CustomMediaForm with choiceset A, and 10 with
choiceset B on the same page, modifying basefields would affect all 20
instances with the last choiceset assigned since basefields is shared
by all class instances.
