Adapted from the multi-chat room implementation at https://github.com/andrewgodwin/channels-examples/tree/master/multichat .
Make a new virtualenv for the project, and run:
pip install -r requirements.txt
Then, you'll need Redis running locally; the settings are configured to
point to localhost, port 6379, but you can change this in the
CHANNEL_LAYERS setting in settings.py.
Finally, run:
python manage.py migrate python manage.py runserver
Run the app:
docker-compose up -d
The app will now be running on: {your-docker-ip}:8000
Note: You will need to prefix python manage.py commands with: docker-compose run --rm web. e.g.: docker-compose run --rm web python manage.py createsuperuser
Finally, run:
docker-compose run --rm web python manage.py migrate
Make yourself a superuser account:
python manage.py createsuperuser
Then, log into http://localhost:8000/admin/ and make a couple of Room objects. Be sure to make one that is set to "staff-only",
Finally, make a second user account in the admin that doesn't have staff privileges. You'll use this to log into the chat in a second window, and to test the authentication on that staff-only room.
Now, open a second window in another browser or in "incognito" mode - you'll be logging in to the same site with two user accounts. Navigate to http://localhost:8000 in both browsers and open the same chatroom.
Now, you can type messages and see them appear on both screens at once. You can join other rooms and try there, and see how you receive messages from all rooms you've currently joined.
If you try and make the non-staff user join your staff-only chatroom, you should see an error as the server-side authentication code kicks in.
