Comment (by Gregory Mariani):
@Jacob
Does this test is also correct with the logic you expect ?
{{{
def test_refresh_foreign_object(self):
# Retrieve the comment via the DB to ensure from_db() is called and
_original_pk is set
comment = Comment.objects.get(pk=self.comment_1.pk)
# Remove the underlying 'user_id' from __dict__ to simulate a cleared
ForeignObject cache
comment.__dict__.pop("user_id", None)
# Call refresh_from_db() to reload the original values from the
database
comment.refresh_from_db()
# Assert that refresh_from_db() has restored 'user' to its original
value
self.assertEqual(comment.user, self.user_1)
}}}
