How to log request and response for 4XX Http status in Django Rest Framework?

Question

The default behaviour of DRF is to throw exception for 5XX, but return valid response with error details for 4XX. I want to log request and response of any API call which fails with 4XX.

Currently the log only shows Bad Request : /path/api/

Answer: Custom exception work fine.

Answer 1

You can define your own custom exception handler and access your request such as:

from rest_framework.views import exception_handler

def custom_exception_handler(exc, context):
    response = exception_handler(exc, context)
    if response is not None:
        response.data['status_code'] = response.status_code
        response.data['request'] = context['request']

    return response

And show your custom handler in settings.py such as:

REST_FRAMEWORK = {
    'EXCEPTION_HANDLER': 'my_project.my_app.utils.custom_exception_handler'
}
