# authenticated :user, lambda {|u| u.role == "admin"} do # root to: "admin/dashboard#show", as: :user_root # end

class LoggedInConstraint def self.matches?(request) request.env['warden'].authenticate? end end

authenticated :user do root 'calendars#index', as: :authenticated_root end unauthenticated :user do root 'pages#home', as: :unauthenticated_root end
