How to start a Celery task with a time delay?

Question

Django

I have a Django model that has an is_activated field. When a new model object is created, is_activated is automatically set to False. In order for this field to become True, the user must fulfill a certain condition within 20 minutes. If within 20 minutes the user has not fulfilled this condition, delete the account.
Whether it is possible to set a timer for a task to delay the execution of the task. Those. queue the task only 20 minutes after saving the model object to check is_activated.
Or is it better to run the task every n-seconds and check the creation time of the model object?
Or are there better solutions to this problem?

Answer 1

And I think it's better to use regular tasks with a delay in time:

@app.task
def main(id):
    pass

main.apply_async(kwargs={"id": id}, countdown=20 * 60)

Add the expired_at field and use it to block attempts to log in after it expires. And you can clean accounts using cron at least once a minute

Answer 4

celery
Periodic Tasks are great for this. expired_at is also a solution, but again it will be necessary to run a task to delete such records once every N time, unless of course there is a task to store them.
