Using just 'settings' without module.

The correct string to load Django settings is 'django.conf:settings'.

💡 Hint

Common Mistakes

Using 'discover_tasks' instead of 'autodiscover_tasks'.

Using AMQP URL when Redis is expected.

autodiscover_tasks() finds tasks.py files in apps.
The broker URL here uses Redis on localhost.

5fill in blank

hard

Fill all three blanks to define a simple Celery task function.

Django

from celery import shared_task

@shared_task
def [1](x, y):
    return x [2] y  # Returns sum

result = [3](4, 5).delay()

Drag options to blanks, or click blank then click option'

Dsum

💡 Hint

Common Mistakes

Using 'sum' as function name which is a built-in function.

Using '-' or '*' instead of '+'.

The task function is named 'add'. It returns the sum using '+'.
The task is called by its name 'add' with .delay() to run asynchronously.
