在graphene_django中使用带有自定义连接的 DjangoFilterConnectionField

Question

我正在尝试使用类似这样的东西：

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，用户节点需要在其元上传递用户连接，而用户连接需要在其元上传递用户。

但是，它会创建一个交叉引用。有什么帮助吗？

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())
