Celery - Get task id for current task

Question

How can I get the task_id value for a task from within the task? Here\'s my code:

from celery.decorators import task
from django.core.cache import cache

@ta         


        

Answer 1

Celery does set some default keyword arguments if the task accepts them. (you can accept them by either using **kwargs, or list them specifically)

@task
def do_job(path, task_id=None):
    cache.set(task_id, operation_results)

The list of default keyword arguments is documented here: http://ask.github.com/celery/userguide/tasks.html#default-keyword-arguments

Answer 2

Since Celery 2.2.0, information related to the currently executed task is saved to task.request (it's called «the context»). So you should get task id from this context (not from keyword arguments, which are deprecated):

@task
def do_job(path):
    cache.set(do_job.request.id, operation_results)

The list of all available fields is documented here: http://celery.readthedocs.org/en/latest/userguide/tasks.html?highlight=requestcontext#context

Answer 3

As of celery 3.1, you can use the bind decorator argument, and have access to the current request:

@task(bind=True)
def do_job(self, path):
    cache.set(self.request.id, operation_results)
