Question

Got a question. Say I have two models in a many-to-many relationship (Article, Publication). Article A is in Publication One, Two, and Three. I want to remove it from those publications and put it into Publication X. The django documentation covers deleting objects and adding objects, but I don’t want to delete nor add objects, merely ‘move’ them. How would I do this?

Thanks in advance,

J

pubx = Pubblication(.....) pubx.save()  article_obj = Article.objects.get(id=1)  remove_from_lst = ['pubblication a', 'pubblication b', 'pubblication c'] remove_from_qs = Pubblication.objects.filter(name__in=remove_from_lst)  for qs in remove_from_qs:     article_obj.pubblications.remove(qs)  article_obj.pubblications.add(pubx)  article.save()
