Question

При попытке SyncDB со следующими моделями:

class Contact(models.Model): 
    user_from = models.ForeignKey(User,related_name='from_user') 
    user_to = models.ForeignKey(User, related_name='to_user') 

    class Meta: 
     unique_together = (('user_from', 'user_to'),) 

User.add_to_class('following', models.ManyToManyField('self', through=Contact, related_name='followers', symmetrical=False)) 

Я получаю следующее сообщение об ошибке: Ответ

Error: One or more models did not validate: 
auth.user: Accessor for m2m field 'following' clashes with related m2m field 'User.followers'. Add a related_name argument to the definition for 'following'. 

auth.user: Reverse query name for m2m field 'following' clashes with related m2m field 'User.followers'. Add a related_name argument to the definition for 'following'. 
auth.user: The model User has two manually-defined m2m relations through the model Contact, which is not permitted. Please consider using an extra field on your intermediary model instead. 

auth.user: Accessor for m2m field 'following' clashes with related m2m field 'User.followers'. Add a related_name argument to the definition for 'following'.
