Say I want to express a symmetric m2m in a separate model. In other
words, instead of
class Person(models.Model):
...
friends = models.ManyToManyField('self')
I wanted
class Person(models.Model):
...
class Friendship(models.Model):
to_person = models.ForeignKey(Person)
from_person = models.ForeignKey(Person)
...
unique_together = (("to_person", "from_person"),)
so I can add additional attributes to the relationship.
Assuming this is the correct way to go to support additional
attributes, I am guessing I want to create a custom Manager than
handles adding the reverse relationship to the table (and removing it
as well) just like ManyRelatedManager in django.db.model.fields.related.
Is there a nice way to do that, short of just copying a bunch of the
code from ManyRelatedManager?
