I have the following simple worker that I can attach to celery and call from a python program: # -*- coding: utf-8 -*- """ Created on Sat Dec 12 16:37:33 2015 @author: idf """ from celery import Celery app = Celery('tasks', broker='amqp://guest@localhost//') @app.task def add(x, y): return x + y This program calls it # -*- coding: utf-8 -*- """ Created on Sat Dec 12 16:40:16 2015 @author: idf """ from tasks import add add.delay(36, 5) I start celery like

#tasks.py from celery.task import Task class Randomer(Task): def run(self, **kwargs): #run Randomer again!!! return random.randrange(0,1000000) >>> from tasks import Randomer >>> r = Randomer() >>> r.delay() Right now, I run the simple task. And it returns a random number. But, how do I make it run another task , inside that task ? Paulo Scardine You can call other_task.delay() from inside Randomer.run ; in this case you may want to set Randomer.ignore_result = True (and other_task.ignore_result , and so on). Remember that celery tasks delay returns instantly, so if you don't put any limit or

The database is getting all the data correctly, but result = AsyncResult(task_id) raises AttributeError: 'DisabledBackend' object has no attribute '_get_task_meta_for' 回答1: I found a more convenient way to do that. result = celery.AsyncResult(task_id) celery is the Celery
