Redirect url if invalid url

I have this method in my book:

    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 for each book look like this:

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

      

        
        
        
      

    

I want that if there is an error in the url, I redirect to the real url using book.id at the end of the url.

For example, if I go to:

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

      

        
        
        
      

    

I will be redirected to:

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

      

        
        
        
      

    

How can i do this?
