How about overriding form_valid
which does the form saving? Save it yourself, do whatever you want to it, then do the redirect.
class PlaceFormView(CreateView):
form_class = PlaceForm
@method_decorator(login_required)
def dispatch(self, *args, **kwargs):
return super(PlaceFormView, self).dispatch(*args, **kwargs)
def form_valid(self, form):
obj = form.save(commit=False)
obj.created_by = self.request.user
obj.save()
return http.HttpResponseRedirect(self.get_success_url())
