title: Devise with rails 4 not updating user
body: <p>I upgraded an app to rails 4 and everything is working fine. I can sign in and goto my edit page. Also updated the views. When using the standard view, the user is updated. But when I add for example the field :name, this is not updated in the form.</p>
  
  <p>Using devise 3.1.1 and also the gem 'protected_attributes'</p>
  
  <p>Do I need to run some kind of update command on devise or db?</p>
  
  <p>I have also searched this place, finding many different solution, but none will update my user field. I have not added any custom fields.</p>
