如何在django频道休息框架中订阅模型的所有实例？

我想将 API 的行为更改为 JSON 触发（从浏览器调用），但由于我对 Python 的了解有限，我什至无法从 Python 客户端调用它。

有人可以帮我怎么做吗manual https://github.com/hishnash/djangochannelsrestframework#subscribing-to-all-instances-of-a-model显示？这是我的简单客户端：

class GenericAsyncAPIConsumerWith(GenericAsyncAPIConsumer):
    async def websocket_connect(self, message):

        # Super Save
        await super().websocket_connect(message)

        # Initialized operation
        await self.model_activity.subscribe()


class UserConsumer(ObserverModelInstanceMixin, GenericAsyncAPIConsumerWith):
    queryset = Course.objects.order_by("-start_time")
    serializer_class = UserSerializer
    # permission_classes = [IsAuthenticated]


@model_observer(User)
async def model_activity(self, message, observer=None, **kwargs):
    # send activity to your frontend
    await self.send_json(message)    

我觉得文档有点不清楚，这就是解决方案，也做了公关。

class ModelConsumerObserver(AsyncAPIConsumer):
    async def accept(self, **kwargs):
        await super().accept()
        await self.model_change.subscribe()
    
    @model_observer(models.Test)
    async def model_change(self, message, **kwargs):
        await self.send_json(message)

从那时起，websocket 会将模型更改推送给客户端
