Django-celery deprecation error?

Question

I just started up django-celery and got this warning:

DeprecationWarning: 
The `celery.decorators` module and the magic keyword arguments
are pending deprecation and will be deprecated in 2.4, then removed
in 3.0.

`task.request` should be used instead of magic keyword arguments,
and `celery.task.task` used instead of `celery.decorators.task`.

See the 2.2 Changelog for more information.

Here's my test task:

from celery.decorators import task
@task()
def myProcessingFunction():
  print "Zing!"
  return 1

I'm calling it from a view with:

myProcessingFunction.delay()

I can't find any documentation for this error. What's going on?

Answer 1

It's telling you that the decorator you are using (task()) is going to be taken out of subsequent versions of celery so you should look to remove it from your code:

celery.task.taskshould be used instead ofcelery.decorators.task`

so

from celery.task import task # instead of celery.decorators
@task()
def myProcessingFunction():
    print "Zing!"
    return 1

Answer 2

According to http://docs.celeryproject.org/en/latest/internals/deprecation.html#old-task-api it sounds like you should also now change

from celery.task import task 

to

from celery import task
