title: Devise - Redirected to page if account isn't confirmed
body: <p>I'm trying to redirect the user if their account hasn't been confirmed. So this involves two parts of the code:</p>
  
  <ol>
  <li>Redirect the user after they first create the account</li>
  <li>Redirect them if they try to sign in before confirming the account</li>
  </ol>
  
  <p>I need help with the second.</p>
  
  <p>The first I was able to do by putting in <code>after_inactive_sign_up_path_for(resource)</code> in my custom RegistrationsController. I've tried to do the same for a SessionsController, but it didn't work. What do I need to over write in order to properly redirect the user if they haven't confirmed the account yet?</p>
