我是石墨烯的新手，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User类给我这个错误，因为在使用django User类之前，我使用了自己的User定义并且它有效。为什么使用django身份验证框架中的User类给出了标题中提到的错误：
文件“/usr/local/lib/python3.6/site-packages/graphql/type/typemap.py”， 第60行，在reducer中，如果map.type中的type.name：AttributeError：type object '用户'没有属性'名称'
我错过了什么吗？
此致
PD：我正在使用Django 2.0.4

答案 0 :(得分：5)
我隐约记得当Django Model类被意外地用在代码而不是石墨烯类型类时会出现神秘错误。例如，确保您的查询类似于
user = graphene.Field(UserType)
而不是
user = graphene.Field(User)
答案 1 :(得分：0)
根据您的错误建议，Django的默认User模型没有名为name的字段。
相反，它有两个相似的字段first_name, and last_name。
如果您想使用两者的组合，请使用get_full_name()方法。
