Django - Signals

You wrote this signal handler but it runs for every model save, not just the intended one. What is the likely problem?

from django.dispatch import receiver
from django.db.models.signals import post_save

@receiver(post_save)
def handler(sender, instance, **kwargs):
    print("Saved")

AMissing sender argument in the @receiver decorator

BHandler function missing required parameters

Cpost_save signal cannot be used with @receiver

Dprint statement syntax is incorrect

Step-by-Step Solution

Solution:

Step 1: Check the @receiver decorator usage
The decorator lacks the sender argument, so it listens to post_save signals from all senders.
Step 2: Understand why handler runs broadly
Without specifying sender=YourModel, the handler triggers for every model that sends post_save.
Final Answer:
Missing sender argument in the @receiver decorator -> Option A
Quick Check:
Specify sender to ensure handler runs only for specific model [OK]

Quick Trick: Always specify sender in @receiver for model signals [OK]

Common Mistakes:

MISTAKES

Assuming handler runs without sender
Incorrect handler parameters
Thinking print syntax causes failure
