ruby-on-rails - 设置：路由集群的默认值

Question

我目前正在设置一些这样的路线：

  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'}

而且我想知道是否有任何方法可以:defaults => {:format => 'json'}为这个集群中的所有路由设置，而不必为每个路由都写出来。

Answer 1

尝试这样的事情：

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
