Django - Signals

Identify the error in this signal handler code that prevents it from working correctly:

from django.db.models.signals import pre_delete

def cleanup(sender, instance):
    print(f"Cleaning up {instance}")

pre_delete.connect(cleanup)

Aconnect() requires a sender argument

BSignal should be <code>post_delete</code> instead of <code>pre_delete</code>

CHandler function must be a class method

DMissing <code>**kwargs</code> parameter in handler function

Step-by-Step Solution

Solution:

Step 1: Check handler function signature
Django signal handlers must accept **kwargs to avoid errors.
Step 2: Verify the handler parameters
The handler lacks **kwargs, so it will raise an error when called.
Final Answer:
Missing **kwargs parameter in handler function -> Option D
Quick Check:
Handler needs **kwargs = Missing **kwargs parameter in handler function [OK]

Quick Trick: Always include **kwargs in signal handlers [OK]
