How can I create custom exceptions in Django?

To create custom exceptions in Django, you can define a new class that inherits from Python's built-in Exception class.

Can you show me an example of a custom exception?

Sure! Here's a simple example:

class MyCustomError(Exception):
    pass

raise MyCustomError('This is a custom error!')

How do I handle this custom exception in my views?

You can use a try-except block in your views to catch the custom exception like this:

try:
    # some code that may raise MyCustomError
except MyCustomError as e:
    return HttpResponse(f'Error: {e}')

Is it possible to create multiple custom exceptions?

Yes, you can create as many custom exceptions as you need by defining multiple classes that inherit from Exception.
