Django GraphQL AttributeError:模块'；石墨烯&x27；没有属性'；英雄'；

我是Django&GraphQL的初学者，我在第一步遇到了一个问题，我无法接触到GraphiQL，我犯了一个错误

Could not import 'traindjango.schema.schema' for Graphene setting 'SCHEMA'.
AttributeError: module 'graphene' has no attribute 'Heroes'.

你能帮我做点什么吗

Thanx很多

而不是

heroes = graphene.Heroes(HeroesType)

你需要

heroes = graphene.List(HeroesType)

英雄

是您的模型，不属于石墨烯

然后您需要将

resolve\u链接重命名为
resolve\u英雄

另外，好的做法是用单数命名django模块，即英雄，而不是英雄。您可以在
Meta
中设置复数的详细名称，前提是它不只是添加一个“s”
