Question

https://prnt.sc/qhg1wq

我有无法解决的问题。我检查了代码中的所有内容，它似乎可以正常工作，但是当我运行服务器并转到Insomnia或localhost：8000 / graphql并键入投票查询时，似乎根本不存在，但是在代码中却有该查询。它是一个简单的厨师应用程序，您可以与通过JWT令牌进行身份验证的用户进行投票。没有那么多代码，使我无法了解所有我制作的模型和模式，并且在使用graphql失眠时仍然会出现此错误。

links / models.py

from django.db import models
from django.conf import settings

class Link(models.Model):
    url = models.URLField()
    description = models.TextField()
    posted_by = models.ForeignKey(settings.AUTH_USER_MODEL, null=True, on_delete=models.CASCADE)

class Vote(models.Model):
    user = models.ForeignKey(settings.AUTH_USER_MODEL, on_delete=models.CASCADE)
    link = models.ForeignKey('links.Link', related_name='votes', on_delete=models.CASCADE)

links / schema.py（linkapp）

import graphene
from graphene_django import DjangoObjectType

from .models import Link, Vote
from users.schema import UserType

class LinkType(DjangoObjectType):
    class Meta:
        model = Link

class VoteType(DjangoObjectType):
    class Meta:
        model = Vote


class Query(graphene.ObjectType):
    links = graphene.List(LinkType)
    votes = graphene.List(VoteType)

    def resolve_links(self, info, **kwargs):
        return Link.objects.all()

    def resolve_votes(self, info, **kwargs):
        return Votes.objects.all()


class CreateLink(graphene.Mutation):
    id = graphene.Int()
    url = graphene.String()
    description = graphene.String()
    posted_by = graphene.Field(UserType)

    class Arguments:
        url = graphene.String()
        description = graphene.String()

    def mutate(self, info, url, description):
        user = info.context.user or None

        link = Link(
            url=url,
            description=description,
            posted_by=user,
        )

        link.save()

        return CreateLink(
            id=link.id,
            url=link.url,
            description=link.description,
            posted_by=link.posted_by,
        )

# Add the CreateVote mutation
class CreateVote(graphene.Mutation):
    user = graphene.Field(UserType)
    link = graphene.Field(LinkType)

    class Arguments:
        link_id = graphene.Int()

    def mutate(self, info, link_id):
        user = info.context.user
        if user.is_anonymous:
            raise Exception('You must be logged in to vote')

        link = Link.objects.filter(id=link_id).first()
        if not link:
            raise Exception('Invalid Link')

        Vote.objects.create(
            user=user,
            link=link,
        )

        return CreateVote(user=user, link=link)
# Add the mutation to the Mutation class
class Mutation(graphene.ObjectType):
    create_link = CreateLink.Field()
    create_vote = CreateVote.Field()

users / schema.py

from django.contrib.auth import get_user_model

import graphene
from graphene_django import DjangoObjectType



class UserType(DjangoObjectType):
    class Meta:
        model = get_user_model()


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

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

# queries
class Query(graphene.AbstractType):
    me = graphene.Field(UserType)
    users = graphene.List(UserType)


    def resolve_me(self, info):
        user = info.context.user
        if user.is_anonymous:
            raise Exception('Not logged in!')

        return user

    def resolve_users(self, info):
        return get_user_model().objects.all()

在名为testmodel的主文件中是settings.py和url.py，我也拥有schema.py来注册所有突变和查询。

schema.py

import graphene
import graphql_jwt

import links.schema
import users.schema

class Query(links.schema.Query, users.schema.Query,  graphene.ObjectType):
    pass


class Mutation(links.schema.Mutation, users.schema.Mutation, graphene.ObjectType):
    token_auth = graphql_jwt.ObtainJSONWebToken.Field()
    verify_token = graphql_jwt.Verify.Field()
    refresh_token = graphql_jwt.Refresh.Field()

schema = graphene.Schema(query=Query, mutation=Mutation)

那是我拥有的所有代码，我无法查询投票。我在上面向您显示的打印屏幕中收到该错误。我无法查询“查询”类型的字段投票。

我想念谁？

无法在yype查询中查询激发的“投票”，名称Votes未定义GraphQL，Django
