AttributeError: объект 'TaggableManager' не имеет атрибута 'primary_key'

Question

Когда я пытаюсь выполнить новую миграцию, используйте функцию -auto. python manage.py schemamigration blogger --auto показывает:

You cannot use --auto on an app with no migrations. Try --initial. 

Так что я запустить первую миграцию снова в моем терминале python manage.py schemamigration blogger --initial. Я получил эту ошибку:

AttributeError: 'TaggableManager' object has no attribute 'primary_key' 

И это models.py для приложения блоггера

from django.db import models 
from taggit.managers import TaggableManager 

# Create your models here. 
class Post(models.Model): 
    title = models.CharField(max_length=100) 
    body = models.TextField() 
    created = models.DateTimeField() 
    tags = TaggableManager() 

    def __unicode__(self): 
     return self.title

Taggit известно запутать Юг они даже упомянуть об этом где-то в глубине там документации. Посмотрите на http://south.readthedocs.org/en/latest/customfields.html#field-name-patterns и посмотрите, поможет ли это.

В основном вы должны сказать Юг игнорировать taggit использовать что-то вроде:

from south.modelsinspector import add_ignored_fields 
add_ignored_fields(["^taggit\.managers"])
