Rails中子域的资源ID

Question

我的网址是：

http://website.com/academies/1

http://website.com/academies/1/courses

http://website.com/academies/1/courses/1

http://website.com/academies/1/courses/1/lessons

http://website.com/academies/1/courses/1/lessons/1

但我想为每个学院使用它子域名

http://1.website.com/
http://1.website.com/courses/
http://1.website.com/courses/1
http://1.website.com/courses/1/lessons
http://1.website.com/courses/1/lessons/1

我想这样做，但不应该是强制性的。两个网址的签名应该同时有效

的routes.rb

resources :academies do

    resources :users
    resources :courses
    resources :posts
