Using Django Server Sent Events with Database post save

Django is build around the request/response cycle which means that it doesn't work well with websockets or even SSE. In your example there is no way to propagade the post_save signal to the view unless you use subscribe to a queue (rabbitmq, redis pubsub) in the view and send data in the signal handler.

Consider other solutions to push from the server:

• Long polling
• Django channels
• An asynchronus solution like nodejs or tornado instead or alongside Django
