title: How to redirect user after sign in with Devise, and how to add method to Devise registration controller
body: <p>Using Rails 3.2.8, Devise 2.1.2, &amp; Simpleform 2.0.2</p>
  
  <p>I'm trying to redirect user upon successful sign in &amp; sign out using devise.</p>
  
  <p>So do I need to modify the controller if so how (specifics)? 
  Or do I need to implement <a href="https://github.com/plataformatec/devise/wiki/How-To%3a-Redirect-to-a-specific-page-on-successful-sign-in-or-sign-out" rel="nofollow">the redirect helper</a>, if so where do I put the helper?  </p>
  
  <p>Thanks a ton.</p>
