How to route to a path/file in Rails?

Question

I have a subdomain that need to point to a folder inside the public folder.

I would be searching for something like this:

constraints DomainConstraint.new(CONFIG[:short_domain]) do
  match '/:id' => '/path/to/folder/with/files/:id'
end

There is any build in way? Or a gem?

Answer 1

I'd use the routing as-is and use send_file , but there may well be a cleaner way that doesn't involve writing an (admittedly trivial) action. (Or handle it at a higher level, depending on what server you're using, I suppose.)
