Rerouting custom routes when user is not authenticated (Devise, rails gem) -

i want reroute non-authenticated user login page, lets route http://localhost:3000/users/sign_in aka devise/sessions#new right default devise edit page when not logged in since built in. custom routes break app if you're not logged in since not apart of devise reroutes. how set these routes reroutes if not logged in? quoting directly devise below, i'm still @ loss on how implement routes, should code like?

goes inside lib

  class customfailure < devise::failureapp     def redirect_url        new_user_session_url(:subdomain => 'secure')     end      # need override respond eliminate recall     def respond       if http_auth?         http_auth       else         redirect       end     end   end , add following in config/initializers/devise.rb:    config.warden |manager|     manager.failure_app = customfailure   end 

goes inside initializers

 config.warden |manager|     manager.failure_app = customfailure   end 

you can try in routes.rb

authenticated :user   devise_scope :user     root to: "dashboard#index"   end end  unauthenticated   devise_scope :user     root to: "homepage#index"   end end
