How can I log 404 errors in Django?

You can log 404 errors in Django by using middleware to capture the response and log it using Django's logging framework.

Can you show me an example of the middleware?

Sure! You can create a custom middleware like this:

import logging
from django.http import HttpResponseNotFound

logger = logging.getLogger('django.request')

class Log404Middleware:
    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.error(f'404 error at {request.path}')
        return response

Where do I add this middleware in my Django project?

You should add your middleware to the MIDDLEWARE setting in your settings.py file, like this:

MIDDLEWARE = [
    ...,
    'yourapp.middleware.Log404Middleware',
    ...,
]

Is there a way to customize the log message?

Yes, you can customize the log message by modifying the string in the logger.error() call to include any additional information you want.
