invoke celery task from tornado [duplicate]

Answer 1

celery has callback function, you could go to http://ask.github.com/celery/userguide/tasksets.html

from celery.task import task
from celery.task.sets import subtask

@task
def add(x, y, callback=None):
    result = x + y

    if callback is not None:
        subtask(callback).delay(result)

    return result
