Hi,
I'm creating a new test and it has users and I delete them:
User.objects.all().exclude(pk=self.user_1.pk).delete()
The User model has related models with on_delete=models.CASCADE which
should be deleted as well.
But in my test, I get this exception:
======================================================================
ERROR: test_like_list_views_titles_with_empty_lists
(speedy.match.likes.tests.test_views.LikeListViewsEnglishTestCase)

The above exception was the direct cause of the following exception:

Ran 1 test in 7.425s
I think this exception is because the users I
deleted. net_accounts_siteprofile refers to the SiteProfile model which
should be deleted when deleting a user by on_delete=models.CASCADE .
What is the problem and how do I fix it?
