Django - Celery and Background Tasks

You want to configure Celery in your Django project to use Redis as the broker and ensure tasks are auto-discovered. Which of the following is the correct minimal setup in your celery.py file?

Afrom celery import Celery app = Celery('proj') app.config_from_object('settings') app.autodiscover_tasks()

Bfrom celery import Celery app = Celery('proj') app.config_from_object('django.conf:settings', namespace='CELERY') app.autodiscover_tasks()

Cfrom celery import Celery app = Celery('proj', broker='redis://localhost:6379/0') app.autodiscover_tasks()

Dfrom celery import Celery app = Celery('proj') app.broker_url = 'redis://localhost:6379/0' app.autodiscover_tasks()

Step-by-Step Solution

Solution:

Step 1: Set broker URL directly in Celery instance
from celery import Celery app = Celery('proj', broker='redis://localhost:6379/0') app.autodiscover_tasks() correctly passes Redis broker URL when creating Celery app, which is a minimal working setup.
Step 2: Evaluate other options
The first uses an invalid path to settings ('settings' instead of 'django.conf:settings'); the second requires defining CELERY_BROKER_URL in Django settings.py first; the third is correct syntax-wise but setting broker_url attribute after creation is less minimal than passing in constructor.
Final Answer:
from celery import Celery app = Celery('proj', broker='redis://localhost:6379/0') app.autodiscover_tasks() -> Option C
Quick Check:
Broker URL in constructor = from celery import Celery app = Celery('proj', broker='redis://localhost:6379/0') app.autodiscover_tasks() [OK]

Quick Trick: Pass broker URL directly to Celery constructor for quick setup [OK]

Common Mistakes:

MISTAKES

Setting broker_url attribute instead of passing in constructor
Misconfiguring config_from_object with wrong settings path
Omitting broker URL causing connection failure
