How to set up Celery and Redis

Correct application operation (in terms of moderation autoapprove functionality, to be precise) requires a running Celery worker and a Redis server. The simplest way to start Redis is:

docker run --rm -p 6379:6379 redis:7

Docker will automatically download the image and run the Redis server with the ports exposed. Redis will be available at 127.0.0.1:6379. You should place this host and port in the environment variable REDIS_URL, which Celery uses through Django's settings.py.

Don't forget to install Celery via pip.

pip install -r requirements.txt

Add in BackEnd .env

REDIS_URL= redis://localhost:6379/0

The Celery worker itself needs to be started in a separate terminal (in the directory where manage.py is located) with the command:

celery -A forum worker --loglevel=info

On some Windows machines, there might be issues, in that case try:

celery -A forum worker --loglevel=info -P eventlet
