What are the best practices for using custom signals in Django?

When using custom signals in Django, it's important to keep them simple and well-documented. Avoid overusing them to prevent complexity.

Can you give an example of a situation where custom signals would be useful?

Sure! Custom signals are useful for decoupling components. For instance, you can use them to notify other parts of your application when a user profile is updated.

How do I connect a signal to a receiver function?

You can connect a signal to a receiver using the @receiver decorator. For example, @receiver(post_save, sender=MyModel) connects the signal to the MyModel save event.

Are there any performance considerations I should be aware of?

Yes, be cautious with performance. Signals can introduce overhead, especially if they trigger multiple receivers. Use them judiciously.
