Comment (by Matt):

 This problem just happened to me on Django 2.2.12 in a migration. e.g.



 {{{
 Category = apps.get_model('blog', 'Category')

 cat = Category.objects.filter(name='Cat A').first()

 for article in list(cat.article_set.all()):
     cat.article_set.remove(article)

 # This deleted all articles that were in the category but were already
 removed()
 cat.delete()
 }}}
