Celery, Django, Heroku -- ImportError: No module named tasks

Question

I am trying to run celery with IronMQ and cache in a Django project on Heroku but I am receiving the following:

2013-04-14T22:29:17.479887+00:00 app[celeryd.1]: ImportError: No module named tasks

What am I doing wrong? The following is my relevant code and djcelery and my app are both in installed apps:

REQUIREMENTS (Rabbit AMQP is in there because I tried that before IronMQ):

PROCFILE:

SETTINGS:

BROKER_URL = 'ironmq://'
CELERY_RESULT_BACKEND = 'ironcache://'

import djcelery
import iron_celery

djcelery.setup_loader()

TASKS:

from celery import task
@task()
def batchAdd(result_length, result_amount):

VIEWS:

from app import tasks
r = batchAdd.delay(result_length, result_amount)
return HttpResponse(r.task_id)

ALSO TRIED (in VIEWS):

from tasks import batchAdd
r = batchAdd.delay(result_length, result_amount)
return HttpResponse(r.task_id)

AND TRIED THIS AS WELL (in VIEWS):

from app.tasks import batchAdd
r = batchAdd.delay(result_length, result_amount)
return HttpResponse(r.task_id)

Also here is my structure:

----__init__.py
----__init__.pyc
----admin.py
----admin.pyc
----forms.py
----forms.pyc
----models.py
----models.pyc

Answer 1

Have you tried to load celery via manage.py ?

python manage.py celery worker --loglevel=info

Answer 2

You can't just run your celery using:

celery -A tasks worker --loglevel=info -E

Celery requires celeryconfig file with -A option. You should run you celery as described in djcelery docs.

python manage.py celery worker --loglevel=info

Also you should fix your views.py as

from app.tasks import batchAdd
