ModelFormMixin's get_form_class() logic broken; fails with custom get_queryset() method

Description

In the ModelFormMixin's get_form_class(), the logic in the else clause is broken:

  • if self.model is set, it uses that instead of the queryset (whereas according to ​the docs "the value of SingleObjectMixin.queryset supersedes the value provided for SingleObjectMixin.model")
  • if self.model is not set, it uses self.queryset.model, ignoring the get_queryset() method

The attached patch fixes both issues

As an aside, perhaps SingleObjectMixin should have a get_model() method that encapsulates and/or shortcuts this logic? On the one hand, using get_queryset().model isn't particularly intuitive, but on the other hand having get_model() may be getting a little too fine-grained.

Things like "settings.LOGIN_URL" perhaps ought to be marked up as ":setting:LOGIN_URL"

(In [14809]) Fixed #14797 -- Corrected the handling of get_form_class() when a custom queryset has been defined, but a model hasn't. Thanks to Gabriel Grant for the report and patch.
