An example of extending UpdateView to use a formset instead of a form

formset_updateview_example.py

class UserUpdateView(AuthenticatorViewMixin, UpdateView):
    model = User
    template_name = 'manager/authenticator/user_list.html'

    def get_form_class(self):
        return modelformset_factory(User, extra=0)

    def get_form_kwargs(self):
        kwargs = super(UserUpdateView, self).get_form_kwargs()
        kwargs['queryset'] = kwargs['instance']
        del kwargs['instance']
        return kwargs

    def get_object(self):
        return self.get_queryset()

Multiple inheritance. You like to live life dangerously.

Don't look at it that way 😄

Treat it like a true mixin and all will be well in the world!

And BTW, the way python implements multiple inheritance is really smart and very powerful if used correctly.
