Django - Signals

What is wrong with this code that tries to connect a receiver to a custom signal?

from django.dispatch import Signal

my_signal = Signal(providing_args=["data"])

def receiver_func(sender, data):
    print(f"Data: {data}")

my_signal.connect(receiver_func)

AThe receiver function must accept **kwargs, not just named arguments

BSignal must be imported from django.signals, not django.dispatch

CThe connect method requires a sender argument

Dproviding_args should be a tuple, not a list

Step-by-Step Solution

Solution:

Step 1: Check receiver function signature
Receivers must accept sender and **kwargs to handle all signal arguments flexibly.
Step 2: Identify mismatch in receiver parameters
The receiver only accepts sender and data, missing **kwargs, which causes errors when extra arguments are sent.
Final Answer:
The receiver function must accept **kwargs, not just named arguments -> Option A
Quick Check:
Receiver needs **kwargs for signal args [OK]

Quick Trick: Receiver functions always need **kwargs parameter [OK]

Common Mistakes:

MISTAKES

Forgetting **kwargs in receiver signature
Importing Signal from wrong module
Assuming connect requires sender argument
Confusing list and tuple for providing_args
