Django - Celery and Background Tasks

ACall <code>send_welcome_email(user.id)</code> directly inside the signal handler

BConnect a signal handler that calls <code>send_welcome_email.delay(user.id)</code> after user creation

CUse a signal to call <code>send_welcome_email.run(user.id)</code> synchronously

DCall <code>send_welcome_email.delay()</code> before the user is saved

Step-by-Step Solution

Solution:

Step 1: Understand the goal
We want to send the email asynchronously after the user is created to avoid slowing registration.
Step 2: Use Django signals with Celery correctly
Connect a signal (like post_save) to call send_welcome_email.delay(user.id) after user creation, queuing the task.
Final Answer:
Connect a signal handler that calls send_welcome_email.delay(user.id) after user creation -> Option B
Quick Check:
Signal + .delay() after save = async email send [OK]

Quick Trick: Use signals to trigger .delay() after user save [OK]

Common Mistakes:

MISTAKES

Calling task directly inside signal, blocking request
Calling .run() which is synchronous
Calling .delay() before user exists in DB
