在应用程序中的芹菜（Django）中添加定期任务

Question

In celery 4> the periodic_task decorator is deprecated. The recommendation now is to define every periodic task inside where you initialize celery (based on what I can find, and the docs ).

In my django setup, I have a lot of small apps, and having a central place to setup period tasks won't do it.

I am still learning my way around celery, but I think my solution is "good". Is this the wrong way to solve this, or is there another way now that periodic_task is gone?

from celery.schedules import crontab
from lib.celery_instance import app  # The celery instance

@app.task()
def mytask():
    # do something...
    return 123

app.add_periodic_task(crontab(hour=8, minute=45), mytask.s())

Answer 1

Another approach to centrally manage the periodic tasks could be to define a dict in the settings.

CELERY_BEAT_SCHEDULE = {
    'some name': {
        'task': 'myapp.tasks.do_something',
        'schedule':  crontab(hour=0, minute=0),
    }
}
