you can this:

class person(models.model):     name = models.charfield(max_length = 255)     occupation = models.charfield(max_length = 255)     friends = models.manytomanyfield('self', through = 'personfriends',            symmetrical = false)     #     ^^^^^^^^^^^     # has false when using `through` models. or else      # model not validate.  class personfriends(models.model):     source = models.foreignkey(person, related_name = 'source')     #                                  ^^^^^^^^^^^^     # need different `related_name` each when have      # multiple foreign keys same table.       target = models.foreignkey(person, related_name = 'target')     comment = models.charfield(max_length = 255)
