Question

我正在调用python manage.py syncdb来为几个模型创建MySQL表，但该命令无法返回以下错误响应：

'AutoField'对象没有属性'related_db_type。'

非常感谢任何有关如何解决此错误的建议。

return     rel_field.related_db_type(connection=connections[router.db_for_read(rel_field.model)])
AttributeError: 'AutoField' object has no attribute 'related_db_type'

模型简称为User，由单个字符字段组成：

class User(models.Model):
    name = models.CharField(max_length = 200)

当我在没有在INSTALLED_APPS中输入任何模型的情况下调用python manage.py syncdb时，也会出现此错误。

我在Mac OS X Lion上运行MySQL社区服务器5.5.20。

编辑：重新安装django解决了这个问题。
