How can I handle error responses in a Django API?

In Django, you can handle error responses by using custom exception handlers. You can define a function that formats the error response.

Can you show me an example of a custom exception handler?

Sure! You can create a function like this:

def custom_exception_handler(exc, context):
    response = {'error': str(exc)}
    return Response(response, status=400)

How do I register this custom handler in my Django settings?

You can register it in your settings.py file like this:

REST_FRAMEWORK = {
    'EXCEPTION_HANDLER': 'myapp.utils.custom_exception_handler',
}

What about handling validation errors?

For validation errors, you can catch them in your serializer and return a structured response with the errors.
