Expiration of results - tasks not cleaned

[elavaud]

Hello,

• django = "^4.1.7"
• celery = "^5.2.7"
• redis = "^4.5.1"
• django-celery-results = "^2.4.0"
• django-celery-beat = "^2.4.0"

Sorry, a few posts already about this, but can not make it work.
I made a test project with the following settings (it is dumb, but I just want to try out celery)

settings.py:

CELERY_BROKER_URL = "redis://localhost:6379"
CELERY_RESULT_BACKEND = 'django-db'
CELERY_RESULT_EXTENDED = True
CELERY_RESULT_EXPIRES = 10

tasks.py:

@shared_task()
def list_users():
    return list(User.objects.values())

Then launched through a submission of form with

list_users.delay()

Three terminals running:

• ./manage.py runserver
• celery -A django_celery worker -l info
• celery -A django_celery beat -l INFO

First, I am a bit confused on the variable name to use. Some say to use CELERY_RESULT_EXPIRES some say CELERY_TASK_RESULT_EXPIRES. Anyway, none works.

Task results are well created, but never cleaned (well, at least not in the 10 seconds I set up).

Anything I missed?
