Flask - Background Tasks

Why is it important to use the @celery_app.task(bind=True) decorator when defining tasks that need to retry on failure?

ABecause it automatically retries the task without extra code.

BBecause it makes the task run synchronously.

CBecause it passes the task instance as the first argument, allowing access to retry methods.

DBecause it disables retries and forces failure.

Step-by-Step Solution

Solution:

Step 1: Understand bind=True effect
It passes the task instance as the first argument (usually self), enabling use of methods like self.retry().
Step 2: Clarify retry control
Retries are not automatic; you must call self.retry() inside the task, which requires binding.
Final Answer:
Because it passes the task instance as the first argument, allowing access to retry methods. -> Option C
Quick Check:
bind=True gives task instance for retries [OK]

Quick Trick: Use bind=True to access self.retry() in tasks [OK]
