How to logging information about 404 error while Debug = False

I have a django project on production. In my settings.py file Debug=False to avoid security risks which arrises when Debug=True I heard about python logging module which I am trying to set up. But after reading documentation like I understand I should put logging instances in each piece of code where error can be arrised, but what if I need to handle 404 errors? How I can handle them? Please anyone guide me

I think there is quite a bunch of information around about 404 handling in django. The most basic thing might be the 404 view that you can override with your custom logics (which i think is not preferred, but might come in handy in some specific cases): https://docs.djangoproject.com/en/3.0/topics/http/views/#customizing-error-views

The preferred method would be going deeper in to the core of request and response handling where you can manipulate your requests having a response status_code of 404 or what so ever. In your middleware you can extend and override behavior of existing middlewares or add your own: https://docs.djangoproject.com/en/3.0/topics/http/middleware/

Below you have simple example of a middleware that checkes the response's status code and uses log.warning when the reponse has a status_code of 404. In this scenario you'll have a single location being responsible of logging the faulty paths that are being requested.

# myproject.middleware.py
import logging

logger = logging.getLogger(__name__)


class PageNotFoundMiddleware(object):
    def __init__(self, get_response):
        self.get_response = get_response

    def __call__(self, request):
        response = self.get_response(request)
        if response.status_code == 404:
            logger.warning("Page not found at {}".format(request.path))
        return response

in your settings.py you can now add the middleware:

MIDDLEWARE = [
   ...
   'myproject.middleware.PageNotFoundMiddleware',
]
