title: Making changes to the devise user controller in rails?
body: <p>I have started using devise for my rails app, however i need to make some changes to the controller logic that devise has, my problem is that i assign users roles, and i want to put in  <code>params[:user][:role_ids] ||= []</code> in the update action so if all the roles are unchecked then it actually works.</p>
  
  <p>whats the best way to do this? </p>
