Hi, thanks for the fast response! I'm trying to use the remove function right now just like this sample code:
# And from the other end >>> p2.article_set.remove(a5) >>> p2.article_set.all() [] >>> a5.publications.all() [] from http://www.djangoproject.com/documentation/models/many_to_many/ I'm doing "Group.objects.get(id=3).members.remove(member1)" and getting this error: 'ManyRelatedManager' object has no attribute 'remove' I also did help to find out what methods ManyRelatedManager had, and indeed it didn't have a 'remove' method, only: clear, create, get_or_create, and get_query_set AND THEN, I tried the remove function with the queryset object, "Group.objects.get(id=3).members.all().remove(member1)" and I got this error: 'QuerySet' object has no attribute 'remove' I'm at a loss as to how I'm supposed to update these relationships....
