   rails.application.routes.draw      namespace :admin        resources :users        "",  to:"users#new"        post "", to:"users#create"      end      "/posts/home",  to: redirect("/posts")      "/posts/about", to: redirect("/about")      resources :posts        resources :comments      end      root "posts#index"      "/home",to: "posts#index"      "/about",to: "posts#about"    end 

if have throught, please tell me, in advance!

you must have actual user object built inside controller. try using inside form instead of symbol :user.

<%= form_for @user, url: admin_users_path |f| %> ...
