我最近开始学习 GraphQL。我为自定义模型创建了一个 Mutation，它工作正常。但是当我尝试对 Django 内置用户模型做同样的事情时。我收到一个错误。无法解决它。我试图通过 GraphQL 创建一个 get_user_model 对象来创建一个新用户。

class CreateUser(graphene.Mutation):
user = graphene.Field(UserType)

class Arguments:
    username = graphene.String(required=True)
    password = graphene.String(required=True)
    email = graphene.String(request=True)

def mutate(self,info,username,password,email):
    user = get_user_model(username=username,email=email)
    user.set_password(password)
    user.save()
    return CreateUser(user=user)

class Mutation(graphene.ObjectType):
    create_user = CreateUser.Field()

得到上述错误。不知道有什么问题。请任何人解释。

解决了这个问题。定义电子邮件参数时有错字，而不是要求它被键入为请求。它现在正在工作。
