AttributeError: type object 'User' has no attribute 'name'
AttributeError: type object 'User' has no attribute 'name'
我是石墨烯新手，我有这个：
from django.contrib.auth.models import User
class UserType(DjangoObjectType):
class Meta:
model = User
基本上，使用 Django 的用户 class 会给我这个错误，因为在使用 django 用户 class 之前，我使用的是我自己的用户定义并且它有效。为什么使用 django 身份验证框架中的用户 class 会给我标题中提到的错误：
File “/usr/local/lib/python3.6/site-packages/graphql/type/typemap.py”,
line 60, in reducer if type.name in map: AttributeError: type object
‘User’ has no attribute ‘name’
我是不是漏掉了什么？
此致
PD：我正在使用 Django 2.0.4

根据您的错误提示，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。
如果您想结合使用两者，请使用 get_full_name() 方法。
这是一个神秘的错误，当 Django 模型 类 在代码中意外使用而不是石墨烯类型 类 时会发生。例如，确保您的查询类似于
user = graphene.Field(UserType)
而不是
user = graphene.Field(User)
