"manage.py dumdata auth.user" returns Error

That's odd that it breaks in that way. I'm not too familiar with the internals of dumpdata. The lines you referenced are using a somewhat internal API django has for adding fields to model classes. Since the User model is off-limits to external apps, I'm using the internal API to add a many-to-many field at runtime. Since the many-to-many data exists in its own table it doesn't affect the auth.User model except to add a nice api for querying relationships.

field = models.ManyToManyField(User, through=Relationship,
symmetrical=False, related_name='related_to')

That adds a new Field, many to many, i think dumdata find a Field ManyToMany and then, can't access to Relationship class, and broke all.. there are no way to delete the ManyToManyField, changing by other attribute that are not a Field?

I faced the same issue. Is there a way to do dumpdata/loaddata on the django auth user model without commenting out those lines?

Could this bug be related? https://code.djangoproject.com/ticket/14226

@epicserve Thanks for that. Looks like the same issue to me.

Not sure the resolution here.
