Celery ImportError: No module named tasks

Question

I'm creating a test scenario for Celery/RabbitMQ/Django. After browsing/reading the various posts similar to mine, I found this one, the closest, but still does not help me. I'm having the "ImportError: no module named tasks" error when executing celery worker.

Celery: 3.1.5 (not dj-celery) Django: 1.5.5

Project structure:

testcele/ (project name)
  mycelery/ (myapp)
    __init__
    tasks

  testcele/
    __init__
    celery_task
    settings

testcele/testcele/celery_task:

  from __future__ import absolute_import
  import os
  from celery import Celery, task, current_task
  from django.conf import settings

  os.environ.setdefault('DJANGO_SETTINGS_MODULE', 'testcele.settings')

  app = Celery('testcele', backend='amqp', broker='amqp://guest@localhost//',
                include=['tasks'])

  if __name__ == '__main__':
      app.start()    

  # Using a string here means the worker will not have to
  # pickle the object when using Windows.
  app.config_from_object('django.conf:settings')
  app.autodiscover_tasks(lambda: settings.INSTALLED_APPS)

testcele/testcele/init.py:

  from __future__ import absolute_import
  from .celery_task import app as celery_app

mycelery/tasks.py:

  from __future__ import absolute_import
  from celery import Celery, task, current_task, shared_task


  @shared_task()
  def create_models():
    .
    .
    .

I'm running: "celery worker -A testcele -l INFO", at the "testcele/" sub-dir. I have also tried running from testcele/testcel sub-dir, from testcele/mycelery, replacing "testcele" on the celery worker command with "tasks" or "mycelery". Obviously, this gives other errors.

What I am missing?

Thanks, Ricardo

Try adding a __init__.py file in your mycelery folder to make it a module. If that didn't work specify the tasks when defining your app. Like so:

app = Celery('testcele', backend='amqp', broker='amqp://guest@localhost//',
                include=['mycelery.tasks'])
