Why not to use rails built in views?

In your controller add this method:

class StaticPagesController < ApplicationController
  def robots
    render :layout => false, :content_type => "text/plain", :formats => :txt
  end
end

In the view create a file: app/views/static_pages/robots.txt.erb with robots.txt content

In routes.rb place:

get '/robots.txt' => 'static_pages#robots'

Delete the file /public/robots.txt

You can add a specific business logic as needed, but this way we don't read any custom files.
