QUESTION
I'm trying to set a server-side event correctly with Traefik to no avail. I have a Django server that has a URL that sends sse, I can proxy easily with nginx with this simple conf:
...ANSWER

Complete explanation on the issue.
Once fixed the headers everything worked.

I am trying to set up my Django project on Heroku. It's my first time doing so.
When deploying it succeeds but when opening up the view I get this message: ImproperlyConfigured: Requested setting INSTALLED_APPS, but settings are not configured. (full traceback below).

I have created an async view, setup asgi configuration, and run gunicorn with a Uvicorn worker. When swarming this server with 10 users concurrently, they are served synchronously. What do I need to configure in order to serve 10 concurrent users an async view?

- I am working with Django 3.2.10 and Python 3.9.
- I have installed

QUESTION
I am running Django 3.2.10 and I am using Django Channels with daphne and gunicorn. I can get my websocket code to run and function without issue but when I go to access any of my django models I hit a snag. I'm doing something like this:
...ANSWER
Answered 2022-Feb-03 at 22:05So figured out what was wrong. I am using docker-compose and on creating the containers, I never shared the DB variables in the environment of the daphne server. As I was focused on the websockets it never arose until I tried to access the db via the Django model. Anyways all is good now but I'll leave this here in case someone was as silly as I was!

Install daphne
You can use daphne 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.
