Hello,
Im reading a django book and it adds friends to user authentication
system by making:
(was .96)
class Friendship(models.Model):
from_friend = models.ForeignKey(
User, related_name='friend_set'
)
to_friend = models.ForeignKey(
User, related_name='to_friend_set'
)
def __str__(self):
return '%s, %s' % (
self.from_friend.username,
self.to_friend.username
)
class Admin:
pass
class Meta:
unique_together = (('to_friend', 'from_friend'), )
But for this to work, you have to add friendship both ways. Ex/ user1 -
> user2 and user2 -> user1 which means almost duplicate entries in
this model. And anytime you modify one friendship, you have to do the
same to the other one.
Is there a better way to do this so that only one entry exists in the
db? Any suggestions are welcome!
Kevin
