如何合并路由声明（子域或令牌）？

Question

我有一个可以通过多种方式访问​​的模型模型：通过子域或令牌

• http://model1.domain.com
• http://domain.com/j4h7

我有以下路线

resources :model, :constraints => {:model_id => /[a-zA-Z0-9]{4}/} do
  ... (nested resources...)
end
resources :model, :constraints => {:subdomain => /.+/} do
  ... (same as above: nested resources...)
end

所以我目前必须复制这两种情况的所有路线。

有没有办法只声明一次？

Answer 1

def nested_routes
  get :some_route
  post :some route
  resources :some_resources
end

resources :model, :constraints => {:model_id => /[a-zA-Z0-9]{4}/} do
  nested_routes
end

resources :model, :constraints => {:subdomain => /.+/} do
  nested_routes
end
