title: Client-side authentication with emberjs and device in Rails4
body: <p>Working with user resources is an essential part of every application an so there it's a task which should be automated as much as possible. 
  As for Ember I found a tutorial <a href="https://github.com/heartsentwined/ember-auth-rails-demo/wiki" rel="nofollow">https://github.com/heartsentwined/ember-auth-rails-demo/wiki</a>
  which describes how it can communicate with devise-based authentication system. And, wow, it's a hell of a boilerplate:)
  Have something changed with new devise for Rails4 or things are the same? </p>
