How can I implement custom signals in Django?

To implement custom signals in Django, you can use the built-in signals framework. First, define your signal using django.dispatch.Signal.

Can you show me an example of defining and sending a custom signal?

Sure! Here's a simple example:

from django.dispatch import Signal

# Define a custom signal
my_signal = Signal(providing_args=['arg1', 'arg2'])

# Function to send the signal
def my_function():
    my_signal.send(sender=my_function, arg1='value1', arg2='value2')

How do I connect a receiver to this signal?

You can connect a receiver function to your signal using the connect method:

from django.dispatch import receiver

@receiver(my_signal)
def my_receiver(sender, **kwargs):
    print('Signal received:', kwargs)
