class Thing(models.Model): foreground_color = models.ForeignKey(Color, related_name='thing_foreground') background_color = models.ForeignKey(Color, related_name='thing_background')
The admin delete view for a Color will correctly warn about the cascade deletions of all Things with that foreground_color. However, it will not show the deletions of Things with that background_color, and they will be deleted. This is surprising and dangerous behavior.
A patch and regression test are included.
