Rails 4路由命名空間/關注URL變量或參數

Question

我有一個應用程序，有一些令人討厭的特定路線的應用程序的日曆部分。他們看起來像這樣：

MyApp::Application.routes.draw do 
    ... 
    day_constraints = { year: /\d{4}/, month: /\d{1,2}/, day: /\d{1,2}/ } 
    get 'days/:month/:day/:year', to: 'schedule#day', constraints: day_constraints, as: :schedule_day 
    get 'days/:month/:day/:year/print', to: 'schedule#day_print', constraints: day_constraints 
    get 'days/:month/:day/:year/route', to: 'routes#index', constraints: day_constraints 
    ... 
end 

正如你所看到的，這裏有很多重複。他們都轉到時間表控制器。我想知道是否有辦法減少重複。我在想一個命名空間或看起來像這樣的擔憂：

MyApp::Application.routes.draw do 
    ... 
    day_constraints = { year: /\d{4}/, month: /\d{1,2}/, day: /\d{1,2}/ } 
    namespace 'days/:month/:day/:year' constraints: day_contstraints do 
    get 'print', to: 'schedule#day_print' 
    get 'route', to: 'routes#index' 

    root to: 'schedule#day' 
    end 
    ... 
end 

但是，這將引發一個錯誤：

'day/:month/:day/:year/schedule' is not a supported controller name. This can lead to potential routing problems. 

如何清理它的任何建議？

Answer 1

嘗試使用scope代替namespace和get "/" => "schedule#day"代替root to: 'schedule#day'：

day_constraints = { year: /\d{4}/, month: /\d{1,2}/, day: /\d{1,2}/ } 
scope 'days/:month/:day/:year', constraints: day_constraints do 
    get 'print', to: 'schedule#day_print' 
    get 'route', to: 'routes#index' 
    get '/', to: 'schedule#day' 
end 

我也不得不添加的範圍和約束之間的逗號。
