設置：默認路由集羣

Question

我目前設置多條航線上，像這樣：

post '/create', :to => 'reports#create', :defaults => {:format => 'json'} 
    get '/all', :to => 'reports#index', :defaults => {:format => 'json'} 
    delete '/:id', :to => 'reports#destroy', :defaults => {:format => 'json'} 
    get '/:id', :to => 'reports#show', :defaults => {:format => 'json'} 
    root :to => 'reports#index', :defaults => {:format => 'json'} 

，我想知道是否有任何的方式來設置:defaults => {:format => 'json'}所有在此羣集中的路線，而不必寫出每一個。

Answer 1

嘗試這樣：

defaults { :format => :json } do 
    post '/create', :to => 'reports#create' 
    get '/all', :to => 'reports#index' 
    delete '/:id', :to => 'reports#destroy' 
    get '/:id', :to => 'reports#show' 
    root :to => 'reports#index' 
end
