在 graphene_django 中将 DjangoFilterConnectionField 与自定义连接一起使用

Question

我正在尝试使用与此类似的东西：

class User(DjangoObjectType):
    class Meta:
        model = auth_models.User
        filter_fields = ('email', )
        interfaces = (Node, )
        connection = UserConnection


class UserConnection(Connection):
    extra = graphene.String()

    class Meta:
        node = User

class Query(graphene.ObjectType):
    users_connection = DjangoFilterConnectionField(
        User,
        where=UserWhereInput()
    )

根据我的理解，User 节点需要在其元数据上传递 UserConnection，而 UserConnection 需要在其元数据上传递给 User。

但是，它创建了一个交叉引用。有帮助吗？

答案可以在这里找到：

https://github.com/graphql-python/graphene-django/issues/304

class UserConnection(Connection):
    extra = graphene.String()

    class Meta:
        abstract = True


class User(DjangoObjectType):
    class Meta:
        model = auth_models.User
        filter_fields = ('email', )
        interfaces = (Node, )
        connection_class = UserConnection


class Query(graphene.ObjectType):
    users_connection = DjangoFilterConnectionField(User, where=UserWhereInput())
