Would it be possible to permit the changing of status codes on form_invalid? We had a form where we wanted to return a 400 status code when a validation error occurs, but by default Django spits out a 200 error code. In other words, following the example at https://docs.djangoproject.com/en/dev/topics/class-based-views/generic-editing/#ajax-example, we'd like to return a 400 on a non-ajax request as well.
Here's the change I'd like to propose. On line 78 of django/views/generic/edit.py:
def form_invalid(self, form, **kwargs): """ If the form is invalid, re-render the context data with the data-filled form and errors. """ return self.render_to_response(self.get_context_data(form=form), **kwargs)
This would permit doing something like this:
response = super(AjaxableResponseMixin, self).form_invalid(form, status=400)
Alternatively, a failure status code property may be more intuitive to developers, but I think the above permits a bit more flexibility in terms of modifying other attributes of the response as well.
