Save 404 Error's URL in Django in models

I figured it would be useful to collect all 404 errors and store them in a model.

These errors can/should be useful in writing (or re-writing) urls for designing a new web project. Also, as you might do, people who automatically type in http://www.domian.com/news or http://www.domian.com/productsor http://www.domian.com/facebook

It would also be useful when people type links in incorrectly and you can develop a redirect for it.

I just don't know how I would execute something like this. Any ideas?

Thanks for your suggestions!

Thanks to a previous answer, I've made this:

#middleware.py (Under the Analytics App)


from django.http import HttpResponseNotFound, HttpRequest
from analytics.models import Site_Error

class Catch404Middleware(object):
     def process_response(self, request, response):
         if isinstance(response, HttpResponseNotFound):
        try:
            new_save,created = Site_Error.objects.get_or_create(error=request.path)
            new_save.times += 1
            new_save.save()
        except:
           new_save = False
    return response

#models.py (Ananlytics App)

class Site_Error(models.Model):
    error = models.CharField(max_length=8000)
    times = models.IntegerField(default=0)
    timestamp = models.DateTimeField(auto_now_add=True)

    class Meta:
         ordering = ('-timestamp',)
         verbose_name = "Error"
         verbose_name_plural = "Errors"

     def __unicode__(self):
         return self.error


#in settings.py 
MIDDLEWARE_CLASSES = (
'django.middleware.common.CommonMiddleware',
'django.contrib.sessions.middleware.SessionMiddleware',
'django.middleware.csrf.CsrfViewMiddleware',
'django.contrib.auth.middleware.AuthenticationMiddleware',
'django.contrib.messages.middleware.MessageMiddleware',
'django.contrib.flatpages.middleware.FlatpageFallbackMiddleware',
'analytics.middleware.Catch404Middleware',
)

This code will save all requested paths into the Site_Error model. There is much more you can do with this so I suggest you look in Django documentation on middleware just as recommended by an answer before.

The easiest way to do that would be to write custom middleware that handles 404s. See the Django documentation on middleware.

A very simple example middleware class that triggers on a 404:

from django.http import HttpResponseNotFound

class Catch404Middleware(object):
    def process_response(self, request, response):
        if isinstance(response, HttpResponseNotFound):
            print "That was a 404!"
        return response

Remember you'll need to install this class into your MIDDLEWARE_CLASSES in settings.py.
