How to access .txt file in root?

Question

Ruby on Rails

There is a .txt file at the root of the domain. It is needed to check the rights on one of the resources.
Worth RoR. When I go to site.ru/file.txt it says: "Routing Error".
What to register in the routing so that it displays the contents of the file?

Answer 1

The question is stupid. I beg your pardon.
Forgot about the public folder...
