How to redirect to 404 (automatically) in Ruby-on-Rails if such page does not exist?

Question

Ruby on Rails

Here is a link to an example groupp.ru/products/ochistnye_sooruzheniya/livnevay... - this is a real page. And if we add anything to the end of the url (for example , groupp.ru/products/ochistnye_sooruzheniya/livnevay... then it will still show this page.
How can I redirect to the 404 page automatically if such a page does not exist ???

Answer 1

How bad things are going for you, apparently...

This is how to redirect errors
But you most likely have a path in the router like
AND *permalink "eats" all the paths, no matter what they write
But how this happens - it already depends on how it is implemented

Answer 2

I have the impression that there are some rules for fallbacks, because no matter how incorrectly the address was written, redirect to some page according to the structure.
