celery parameters has correct number of arguments

Question

I am using celery 4.0 and was following this site. http://docs.celeryproject.org/en/latest/userguide/tasks.html#blog-tasks-py

views.py

task = test2.delay(document.name, document.id)

Tasks.py

@shared_task(name="test2")
def test2(param, job_id):
    return 'The test task executed with argument "%s" ' % param

However, it throws an exception TypeError: test2() takes exactly 1 argument (2 given). This is funny since i have 2 arguments and it works in the site i shown.

I just tried your code and it works fine and the minimal code posted here works fine. You probably have a messed up import (i.e., test2 defined in multiple places) or a stray .pyc file lying around. — 2ps

@2ps I think i forgot to restart celery after modifying my tasks file. I guess this is why it threw the error. Thanks. — aceminer
