hmm, don't know. that's the documented approach. you might want to
investigate intermediary tables/models etc.

Ahh yes possibly. Any downsides to using this?

Re: Many to Many entries being duplicated, any ideas?
Do you want something like this?
friends_new = models.ManyToManyField("self",symmetrical=False)

Hi Guys,
Just bumping this up as I still can't figure out why this is
happening :/

Many to Many entries being duplicated, any ideas?
Hi Guys,
I've got a model that has a Many to Many relationship on one of the
fields. This relationship is basically on itself though like this:
#
class UserProfile(models.Model):
user= models.ForeignKey(User, unique=True)
friends_new = models.ManyToManyField('UserProfile', blank=True,
related_name='friend_set_new')
#
I'm trying to "add" to the friends_new field using this code:
#
# get users
initiator_profile = UserProfile.objects.get(user=request.user.id)
recipient_profile = UserProfile.objects.get(user=username)
# now add them as a friend
initiator_profile.friends_new.add(recipient_profile)
#
Now the problem I'm having is that it is adding the friendship to BOTH
userprofiles, initiator and recipient. And when I try to remove the
relationship, again it removes BOTH. So in the database it has two
entries when I only expect there to be one.
Hope I've made that clear enough, any ideas how to get around this?
Cheers,
Chris
