I have User and Org models, with User having a ForeignKey to Org:
{{{#!python
org = models.ForeignKey('Org', null=True, blank=True,
on_delete=models.SET_NULL)
}}}
If I delete an Org instance then refresh the User instance, then
user.org_id is cleared as expected, but user.org still references the
deleted instance:
{{{#!python
org = create_org()
user = create_user(org)
org.delete()
user.refresh_from_db()
self.assertIsNone(user.org_id) # Works!
self.assertIsNone(user.org) # Fails!
}}}
