QUESTION
I built a docker container with Django, Uvicorn, Nginx and Redis, and am using django-channels but when I run this it says it cannot connect to the websocket and this is seen in the browser console:
WebSocket connection to 'ws://127.0.0.1:8080/ws/notifications/' failed
It is working fine when I use Django's runserver command for development but when I include Nginx and Uvicorn it breaks.

I'm attempting to send consumers.py information to display on the client end outside of consumers.py.
I've referenced Send message using Django Channels from outside Consumer class this previous question, but the sub process .group_send
or .group_add
don't seem to exist, so I feel it's possible I'm missing something very easy.

Answered 2022-Feb-09 at 14:23To anyone looking at this in the future, I was not able to use redis or even memurai in Windows OS due to cost. I ended up using server side events (SSE), specifically django-eventstream, and so far it's worked great as I didn't need the client to interact with the server, for a chat application this would not work.
Eventstream creates an endpoint at /events/
the client can connect to and receive a streaming http response.

QUESTION
i created a websocket with javascripts on the client side...then followed up with setting up my project to handle webocket connections as follows(following the official django-channels documentation). But each time i refresh the page and watch the websocket from the browser console...its fails. i inserted an print statement in the init of the consumer class and it was printed(each time a page containing a websocket was visited or refreshed)..which mean that the routing is working fine...but for some reasons the consumer is not connecting/accepting the connection as expected to the websocket. and again there is no log in the development server as to any websocket connection process.Please can anyone help and suggest a fix.

QUESTION
I use djangorestframework-simplejwt.
I have two Django Projects sharing the same database.
One is django-restframework
One is django-channels
django-restframework login will get JWT
I cannot verify successfully in django-channels
I wrote the test function
restframework verify ok ...ANSWER
Answered 2021-Dec-22 at 08:43Because i don't know how jwt verifies
Now I found that the verification method is SECRET_KEY
in settings.py
As long as different projects use the same SECRET_KEY
.
There is no problem with JWT authentication.

QUESTION
I use Graphql subscriptions with Apollo client on a Vue3 app using Django graphQL Channels and DjangoGraphqlJWT packages in my backend app.
I'm trying to pass a JWT token on the Apollo subscriptions via the connectionParams.
Following this solution. I implemented a Middleware. However Apollo is passing the connectionParams as a payload. I can't find a way to access the payload at the Middleware level, but only on the consumer.
I could access the query string property from the scope argument in the middleware. However, I can't find a way to pass a query argument after the subscription is initiated.
CLIENT SIDE:

Answered 2021-Nov-29 at 03:26I managed to get the token in the consumer payload and inject the user into the context.
QUESTION
I'm using django-channels
and aiortc
, I want to create server to peer
connection as WebRTC
.
In my case, if client send the new-peer
action, then server send the offer.
And after client receive the offer, client send the answer as new-answer
action.
But server can't remember peer
, so can't setRemoteDescription
.
Of course I know server don't remember, but how do I deal with situations where server need to remember instances like mine?
I also looked for session variables, but it seems that only simple values can be stored, and it doesn't seem to have anything to do with the instance.
Please provide helpful documents or solutions related to this.

Install django-channels
You can use django-channels like any standard Python library. You will need to make sure that you have a development environment consisting of a Python distribution including header files, a compiler, pip, and git installed. Make sure that your pip, setuptools, and wheel are up to date. When using pip it is generally recommended to install packages in a virtual environment to avoid changes to the system.
