The documentation for related_name
(https://docs.djangoproject.com/en/1.6/ref/models/fields/#django.db.models.ForeignKey.related_name)
states that if the value is, or ends with, "+", then no reverse
relationship will be created. I'm not sure why you are doing that, but
remove the "+" from the related_name in the ForeignKey definition.
