Django AttributeError:type object'；用户'；没有属性'；名称'；

我刚接触石墨烯，我有这个：

from django.contrib.auth.models import User

class UserType(DjangoObjectType):
    class Meta:
        model = User

基本上，使用Django的用户类给了我这个错误，因为在使用Django用户类之前，我使用的是我自己的用户定义，它工作正常。为什么使用django身份验证框架中的User类会导致标题中提到的错误：

文件“/usr/local/lib/python3.6/site packages/graphql/type/typemap.py”， 第60行，如果map:AttributeError:type对象中的type.name是reducer中的 “用户”没有属性“名称”

我错过什么了吗

问候

PD：我正在使用Django 2.0.4
