Django raising 404 with a message

Question

I like to raise 404 with some error message at different places in the script eg: Http404(\"some error msg: %s\" %msg) So, in my urls.py I included:

<         


        

Answer 1

In my case, I wanted to take some action (e.g. logging) before returning a custom 404 page. Here is the 404 handler that does it.

def my_handler404(request, exception):
    logger.info(f'404-not-found for user {request.user} on url {request.path}')
    return HttpResponseNotFound(render(request, "shared/404.html"))

Note that HttpResponseNotFound is required. Otherwise, the response's HTTP status code is 200.
