Why does Celery work in Python shell, but not in my Django views? (import problem)
- by TIMEX
I installed Celery (latest stable version.)
I have a directory called /home/myuser/fable/jobs. Inside this directory, I have a file called tasks.py:
from celery.decorators import task
from celery.task import Task
class Submitter(Task):
def run(self, post, **kwargs):
return "Yes, it works!!!!!!"
Inside this directory, I also have a file called celeryconfig.py:
BROKER_HOST = "localhost"
BROKER_PORT = 5672
BROKER_USER = "abc"
BROKER_PASSWORD = "xyz"
BROKER_VHOST = "fablemq"
CELERY_RESULT_BACKEND = "amqp"
CELERY_IMPORTS = ("tasks", )
In my /etc/profile, I have these set as my PYTHONPATH:
PYTHONPATH=/home/myuser/fable:/home/myuser/fable/jobs
So I run my Celery worker using the console ($ celeryd --loglevel=INFO), and I try it out.
I open the Python console and import the tasks. Then, I run the Submitter.
>>> import fable.jobs.tasks as tasks
>>> s = tasks.Submitter()
>>> s.delay("abc")
<AsyncResult: d70d9732-fb07-4cca-82be-d7912124a987>
Everything works, as you can see in my console
[2011-01-09 17:30:05,766: INFO/MainProcess] Task tasks.Submitter[d70d9732-fb07-4cca-82be-d7912124a987] succeeded in 0.0398268699646s:
But when I go into my Django's views.py and run the exact 3 lines of code as above, I get this:
[2011-01-09 17:25:20,298: ERROR/MainProcess] Unknown task ignored: "Task of kind 'fable.jobs.tasks.Submitter' is not registered, please make sure it's imported.": {'retries': 0, 'task': 'fable.jobs.tasks.Submitter', 'args': ('abc',), 'expires': None, 'eta': None, 'kwargs': {}, 'id': 'eb5c65b4-f352-45c6-96f1-05d3a5329d53'}

NotRegistered: "Task of kind 'fable.jobs.tasks.Submitter' is not registered, please make sure it's imported."
It's weird, because the celeryd client does show that it's registered, when I launch it.
