URL redirection if wrong url

Question

I have this method in my book model:

    def get_absolute_url(self):
        return "/book/%s/%s/%i/%i/" % ( self.book_title, self.book_editor, self.book_pages, self.id)

So the urls of each book are like this:

example.com/book/the-bible/gesu-crist/938/12/

I want that if there is an error in the url, then I get redirected to the real url by using book.id in the end of the url.

For example if I go to:

example.com/book/A-bible/gesu-crist/938/12/

the I will get redirected to:

example.com/book/the-bible/gesu-crist/938/12/

How can I do that ?

Answer 1

You could create custom HTTP 404 handler.
