Mobile version of views for Ruby on Rails

Question

I\'m after some validation that I\'m doing the right thing. I have my Ruby on Rails application in the following structure:

/home
   about.rhtml<

Rails 4.1 includes Variants, a great new feature that:

Allows you to have different templates and action responses for the same mime type (say, HTML). This is a magic bullet for any Rails app that's serving mobile clients. You can now have individual templates for the desktop, tablet, and phone views while sharing all the same controller logic.

In your case, you only need to set the variant for the iphone in a before_action, e.g:

class HomeController < ApplicationController
  before_action :detect_iphone
  def index

    respond_to do |format|
      format.html               # /app/views/home/index.html.erb
      format.html.phone         # /app/views/home/index.html+phone.erb
    end
  end

  private
    def detect_iphone
      request.variant = :iphone if request.user_agent =~ /iPhone/
    end
end
