Question

routes:

  match '/' => 'site_admin/admin#index'


  resources :link_pages
  resources :services  
  resource :user_session
  resource :account, :controller => "users"
  resources :password_resets
  resources :users
  resources :addresses
  resources :info

  match "/home", :to => 'info#home'
  match "/register", :to => 'users#new'

  root :to => 'info#home'


  match ':controller(/:action(/:id(.:format)))'

so when I got to admin.lvh.me:3000/ it goes to site_admin/admin#index… which is great…
but when I take off the subdomain, and just have lvh.me:3000/ it goes to the same route….

how do I get admin to stay where it is. and no subdomain to go to my root page, as in my routes file?

Answer 1

Routes are parsed in order, so when you request / from any domain it finds “match ‘/’…” first and sends you to the specified page. Your subdomain isn’t coming into play at all. You can use Request-based constraints to route based on subdomain:
