AttributeError：'TaggableManager'對象沒有屬性'primary_key'

Question

當我嘗試使用-auto功能進行新遷移時。 python manage.py schemamigration blogger --auto它表明：

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

所以我在終端python manage.py schemamigration blogger --initial再次運行第一個遷移。我得到這個錯誤：

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

這是models.py的應用博客

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被稱爲混淆南他們甚至提到這個地方有文檔中的深跌。看看http://south.readthedocs.org/en/latest/customfields.html#field-name-patterns，看看它是否有幫助。

基本上你要告訴南忽略taggit使用類似：

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