Django: How to customize an runserver_socketio command for manage.py

Question

I'm writing a realtime chatroom similar to this package with Django. It runs a separate WebSocket server with command

python manage.py runserver_socketio

But I can't figure out how to make the runserver_socketio command load my handler. The only related code I can find in the package is here in django-socketio/django_socketio/management/commands/runserver_socketio.py:

server = SocketIOServer(bind, handler, resource="socket.io")
....
handler = WSGIHandler()

But why on earth is this handler related to my code?

Answer 1

I got it. the manage.py runserver_socketio command starts almost an identical server as manage.py runserver does. The only difference is that this new server can handle websocket protocol.

To see this ,suppose runserver runs on 127.0.0.1:8000 and runserver_socketio on 127.0.0.1:9000. Just visit 127.0.0.1:9000 and you will get the same webpage with 127.0.0.1:8000.

The secret lies in django-socketio/django_socketio/example_project/urls.py, which referencing django-socketio/django_socketio/urls.py. In this second urls.py, we can see that it loads events.py in our project.
