CPendingDeprecationWarning: The broker_connection_retry configuration setting will no longer determine whether broker connection retries are made during startup in Celery 6.0 and above

Description

I found this deprecation warning for the celery;

CPendingDeprecationWarning: The broker_connection_retry configuration setting will no longer
determine whether broker connection retries are made during startup in Celery 6.0 and above.
If you wish to retain the existing behavior for retrying connections on startup,
you should set broker_connection_retry_on_startup to True.

https://docs.celeryq.dev/en/stable/userguide/configuration.html#broker-connection-retry

As the newest celery almost using that version;

cookiecutter-django/{{cookiecutter.project_slug}}/requirements/base.txt

Lines 18 to 20 in b8b470c

	{%- if cookiecutter.use_celery == "y" %}
	celery==5.4.0 # pyup: < 6.0 # https://github.com/celery/celery
	django-celery-beat==2.6.0 # https://github.com/celery/django-celery-beat

Solution

And found the solution at https://stackoverflow.com/a/78088996/6396981

Where we can utilize the following settings to silence the warning by putting the below code into celery.py.

celery_app.conf.broker_connection_retry_on_startup = True

or settings.py;

CELERY_BROKER_CONNECTION_RETRY_ON_STARTUP = True

Just wondering to add this into cookie-cutter-django
