Common Mistakes

Using 'task' instead of 'shared_task' causes import errors.

Importing 'app' is incorrect for task decorators.

The shared_task decorator is used to define tasks in Django with Celery without needing the app instance.

💡 Hint

Common Mistakes

Using '-' subtracts instead of adds.

Using '*' or '/' changes the operation to multiplication or division.

The task adds two numbers, so the operator must be +.

Common Mistakes

Using '@task_task' causes syntax errors.

Using '@celery_task' is invalid.

The correct decorator is @shared_task to define a reusable Celery task.

Common Mistakes

Mixing 'task' and 'shared_task' causes import or decorator errors.

💡 Hint

Common Mistakes

Using 'task' instead of 'shared_task' for decorator causes errors.

Using 'app' or 'worker' is incorrect for these imports.

Use shared_task to import and decorate the task, and crontab to schedule periodic tasks.
