AttributeError：类型对象“用户”没有属性“名称”

本文介绍了AttributeError：类型对象“用户”没有属性“名称”的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！ 问题描述

我是石墨烯的新手，我有这个：

I’m new with graphene and I have this:

from django.contrib.auth.models import User class UserType(DjangoObjectType): class Meta: model = User

基本上，使用Django的User类会给我这个错误，因为在使用django User类之前，我使用了自己的User定义并且可以正常工作。为什么使用django身份验证框架中的User类会给我标题中提到的错误：

Basically, using Django’s User class is giving me this error, because before using the django User class, I was using my own User definition and it worked. Why using the User class from the django authentication framework is giving me the error mentioned in the title:

File / usr / local / lib /python3.6/site-packages/graphql/type/typemap.py中，行中的，如果map中的type.name：AttributeError：类型对象'User'没有属性'name '

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’

我错过了什么吗？

推荐答案

这是一个隐式错误，当意外使用Django Model类时发生在代码中而不是石墨烯类型类。例如，确保您的查询类似于

This is a cryptic error that happens when Django Model classes are accidentally used in code instead of graphene Type classes. For example, make sure that your query is something like

user = graphene.Field(UserType)

而不是

user = graphene.Field(User)
