Answer 1

Django itself is build in blocking manner, i.e. with synchronous approach. So, you cannot open persistent websocket with django app, as it will block entire django thread.

If you want to enable notification/chat within django project environment, i would recommend to use centrifuge. It is written in python, but async (non-blocking) framework is used: tornado.

But, you don't need to even know how it works, as it provides simple REST api to communicate with it.

Simplified workflow, check docs for more details:

1. Start centrifuge at same server, as your django project (or on another but with low latency between them)
2. Your front-end will open websocket with centrifuge, not with django project.
3. When you need to send notification, send it to centrifuge from django via REST api, and centrifuge will deliver it to needed clients!

I've already tried it and it works!
