celery not working in django and just waiting (pending)

i'm trying found how celery is working. i have a project that have about 10 app.now i want use celery .

setting.py:

CELERY_BROKER_URL = 'amqp://rabbitmq:rabbitmq@localhost:5672/rabbitmq_vhost'
CELERY_RESULT_BACKEND = 'redis://localhost'

i created a user in rabbitmq with this info:username: rabbitq and password:rabbitmq . then i create a vhost with name rabbitmq_vhost and add rabbitmq permission to it. all is fine i think because all of error about rabbitmq disappear .

here is my test.py:

from .task import when_task_expiration

def test_celery():
    result = when_task_expiration.apply_async((2, 2), countdown=3)
    print(result.get())

task.py:

from __future__ import absolute_import, unicode_literals
import logging

from celery import shared_task
from proj.celery import app

@app.task
def when_task_expiration(task, x):
    print(task.id, 'task done')
    return True

celery.py:

from __future__ import absolute_import, unicode_literals
import os
from celery import Celery

# set the default Django settings module for the 'celery' program.
os.environ.setdefault('DJANGO_SETTINGS_MODULE', 'proj.settings')

app = Celery('proj')

# Using a string here means the worker doesn't have to serialize
# the configuration object to child processes.
# - namespace='CELERY' means all celery-related configuration keys
#   should have a `CELERY_` prefix.
app.config_from_object('django.conf:settings', namespace='CELERY')

# Load task modules from all registered Django app configs.
app.autodiscover_tasks()

now when i call test_celery() in python shell it's pending.i try to replace @shared_task and @app.task(bind=True) but noting changed.even i try use .delay() instead apply_async((2, 2), countdown=3) and again nothing happend.

i'm trying to use celery to call a function in specific time during this quesation that i ask in past.thank you.

You most likely forgot to run at least one Celery worker process. To do so, execute the following in the shell: celery worker -A proj.celery -c 4 -l DEBUG (here I assumed your Celery application is defined in proj/celery.py as you have Celery('proj') in there)
