how to start a task at a specific time with django & celery

Question

I'm using Celery, and it works for async, but I need to set up an operation to a specific datetime.

For example "on the 30th of August, 2019, at 11:35, do this."

My celery.py is very simple now, but it works:

import time
from datetime import datetime, timedelta
from datetime import date
from celery import shared_task,current_task, task
from celery import Celery

app = Celery()

@app.task
def test():

    print ('1')
    todaynow = datetime.now()

    print todaynow

I call it from view and run print on rabbit

Any idea for how to program a task?

EDIT:

I try in view to call "test"

test.apply_async(eta=datetime(2019, 7, 31, 6, 28))

in flower it receive the task but not execute it, why?

Answer 1

To run a task at a specific time you can pass the eta parameter to apply_async

test.apply_async(eta=datetime.datetime(2019, 8, 30, 11, 35))
