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

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:

import djcelery

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:

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
