Graphene-Django:在模式中组合Query-objects(只接受第一个参数)

问题描述 投票:1回答:1

我试图在Django 2.1中组合位于不同应用程序中的多个Query模式。使用石墨烯-django 2.2(尝试过2.1同样的问题)。 Python 3.7。

Query类仅注册第一个变量。以shop.schema.Query为例。

import graphene
import graphql_jwt
from django.conf import settings

import about.schema
import shop.schema
import landingpage.schema

class Query(about.schema.Query, shop.schema.Query, landingpage.schema.Query, graphene.ObjectType):
  pass

class Mutation(shop.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)

为什么会这样?有没有改变python 3.7中的类?石墨烯教程说这将继承多个......

class Query(cookbook.ingredients.schema.Query, graphene.ObjectType):
    # This class will inherit from multiple Queries
    # as we begin to add more apps to our project
    pass

schema = graphene.Schema(query=Query)

我将我的架构导出到schema.json,以便将它与react relay一起使用。我确实从登陆页面找到了我的对象“集合”查询模式(3.变量)。接力回报:

错误:GraphQLParser:类型为collection的未知字段Viewer。来源:文件AppQuery文件:containers/App/index.js

Relay读取我的schema.json是一个问题吗?

django reactjs graphql graphene-python react-relay

写完这篇文章后,我设法解决了这个问题。我的问题是我在每个应用程序中都有一个Viewer对象。因为我发现有一个viewer-graphql-root很有用,如下所示:

graphql'
  viewer {
    collection {
      somestuff
    }
  }
'

我将Viewer对象移动到根schema.py,如下所示:

class Viewer(about.schema.Query, landingpage.schema.Query, shop.schema.Query, graphene.ObjectType):
  class Meta:
    interfaces = [relay.Node, ]

class Query(graphene.ObjectType):
  viewer = graphene.Field(Viewer)

  def resolve_viewer(self, info, **kwargs):
    return Viewer()

class Mutation(shop.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)
