Great question. If you want to use the existing Admin model from devise, all you need to do is add before_action :authenticate_user! to your admin controllers to force the admin user to be logged in. That should be it!

Thanks @chris for quick response, appreciated. Fully understand your message but the challenge here is that i've generated two devise 'User' & 'Admin', generating 'administrate:install' split error...

λ rails generate administrate:install
DL is deprecated, please use Fiddle
      create  app/controllers/admin/application_controller.rb
       route  namespace :admin do
    DashboardManifest::DASHBOARDS.each do |dashboard_resource|
      resources dashboard_resource
    end

    root controller: DashboardManifest::ROOT_DASHBOARD, action: :index
  end

What is the contents of your app/models/admin.rb file? It sounds like the Admin class isn't defined in there for some reason.

Thanks @chris, below are the contents contained in admin.rb

class Admin < ActiveRecord::Base
  # Include default devise modules. Others available are:
  # :confirmable, :lockable, :timeoutable and :omniauthable 
  devise :database_authenticatable, :recoverable,
         :rememberable, :trackable, :validatable
end

Thanks
