Finally, if the customization at the views level is not enough, you can customize each controller by following these steps:

  1) Create your custom controller, for example a Admins::SessionsController:

    class Admins::SessionsController < Devise::SessionsController
    end

  2) Tell the router to use this controller:

    devise_for :admins, :controllers => { :sessions = "admin/sessions" }

  class << self
    private :new

b.inject(a) {|h, i| h[i]}
