python - 设置普通 Graphite 烯嵌套查询

Question

我已经成功创建了一个响应的全 Graphite 烯查询

query {
    person (id: "Mary") {
        id
        name
    }
}

我现在想扩展它，以便能够循环遍历所有人并为每个人返回类似的数据。

query {
    people {
        count
        allPersons {
           name
        }
    }
}

如何获取 people 中的 resolve_allPersons 解析器来调用每个人的 person 解析器？

Answer 1

您描述的第二个查询可以使用自定义类型完成，例如:

class AllPeopleType(graphene.ObjectType):
    count = graphene.Int()
    all_persons = graphene.List(YourPersonType)

    def resolve_count(self, info, **kwargs):
        # assumed that django used on backend
        return Person.objects.count()

    def resolve_all_persons(self, info, **kwargs):
        return Person.objects.all()

和查询:

class YourQuery(object):
    # person = ...
    people = graphene.Field(AllPeopleType)

    def resolve_people(self, info):
        return AllPeopleType()
