that wouldnt remove the strict distinction betwen form_for_model
and form_for_instance (the only difference i see, is that one of them
has a initial instance
and i really would like to have a base class, since i like to avoid
monkey-patching
using the function result as a base-class would be an acceptable
solution
but i would apreciate a different use-pattern
default forms:
MyForm = modelForm(model)
MyForm() #for add-forms
MyForm(instance=foo) or Myform(object_id=bar) # edit forms
class Myform(modelForm(model)):
# extend me :)
pass
cause i dislike recreating the form classes every time someone wants
to edit something
