接口中包含的Graphql类型未添加到graphene django中的架构

我有一个由两个具体类型实现的接口类型

interface InterfaceType {
  id: ID!
  name: String!
}

 type Type1 implements InterfaceType {
    aField: String
}

 type Type2 implements InterfaceType {
    anotherField: String
}

class InterfaceType(graphene.Interface):
    id = graphene.ID(required=True)
    name = graphene.String(required=True)

class Type1(graphene_django.types.DjangoObjectType):
    a_field = graphene.String(required=False)

    class Meta:
        model = Model1
        interfaces = (InterfaceType,)

class Type2(graphene_django.types.DjangoObjectType):
    another_field = graphene.String(required=False)

    class Meta:
        model = Model2
        interfaces = (InterfaceType,)

只要某些查询或变异使用 Type1 和 Type2 直接。但在我看来,它们只是通过 InterfaceType .

问题是当我试图请求 aField 或 anotherField 通过内联片段:

query {
    interfaceQuery {
        id
        name
        ...on Type1 {
            aField
        }
        ...on Type2 {
            anotherField
        }
    }

使用阿波罗:

import gql from 'graphql-tag';

const interfaceQuery = gql`
    query {
        interfaceQuery {
            id
            name
            ... on Type1 {
                aField
            }
            ... on Type2 {
                anotherField
            }
        }
    }
`;

我得到了错误 "Unknown type "Type1". Perhaps you meant ..."
