"""Mixin for model classes.
This adds a call to `self.full_clean` to every `save`, so that you can
never save a model object in an unaccepted state.
This was meant to be a standard part of Django model classes, but was
left out purely for backwards compatibility_, which is not an issue for
us.
Derive your model from :class:`CleanSave` before deriving from
:class:`django.db.models.Model` if you need the `full_clean` to happen
before the real `save` to the database.
