title: How do I have devise / omniauth redirect to the page from which I signed in from?
body: <p>I have the authentication through omniauth and that link is available on every page through layout/application.html.haml.</p>
  
  <p>However, when they complete the omniauth authentication, they all go to root.</p>
  
  <p>How can I set it up so they redirect to the actual page from which they clicked on the authentication link (which takes them to the oauth provider).</p>
  
  <p>Thanks</p>
