Question

我一直在尝试使用Rails，但发现自己遇到了一个非常简单的问题：我有两个模型，幸存者和位置，它们是在route.rb中嵌套的资源。

Rails.application.routes.draw do
  namespace 'api' do
    namespace 'v1' do
      resources :survivors do
        resources :locations
      end
      resources :abduction_reports
    end
  end
end

这给了我几乎所有我需要的路线。问题在于幸存者和位置是一对一的关联，因此，如果我想更新幸存者的位置，那么端点是否为

PUT /survivors/:survivor_id/location

要解决此问题，我这样做：

Rails.application.routes.draw do
  namespace 'api' do
    namespace 'v1' do
        [...]
        put 'survivors/:survivor_id/location', to: 'locations#update'
    end
  end
end

但这似乎不是正确的方法...我的意思是，它可以在'resources：survivors do ... end'范围内定义吗？

我可能已经在Rails文档中看到了，但是我想我还没有意识到如何使文档示例适应我的问题。

对于单个资源，请使用resource宏：

Rails.application.routes.draw do
  namespace 'api' do
    namespace 'v1' do
      resources :survivors do
        resource :location
      end
      resources :abduction_reports
    end
  end
end
