Question

在我的routes.rb中我有：

  resources :aquariums do
    resources :management_roles
    resources :graphs
    resources :animals
  end
  get 'aquarium', to: 'aquariums#show', :as => :aquarium

最后获得的原因是我在我的应用程序中有“当前水族馆”的概念。如果，例如，current_aquarium设置为1，那么在我的控制器的'show'动作'/ aquarium'获得与'/ aquariums / 1'相同的渲染，代码如

@aquarium_id = params[:id] || current_aquarium.id

现在，我假设这是由于这个不同的路由，这段代码：

<%= link_to aquarium.name, aquarium %>

或

<%= link_to aquarium.name, aquarium_path(aquarium) %>

生成如下路径：

/aquarium.1

我通常期望的地方：

/aquariums/1

右？

每个请求......这是rake routes | grep aquar产生的结果：（我假设这是最后一条混乱的路线，但我认为它会按顺序处理这些。而且，仅仅是因为我最初在顶部有这条路线。把它移到底部假设它会解决的。）

Answer 1

更改最后一条路线：

get 'aquarium', to: 'aquariums#show', :as => :aquarium

到此：

get 'aquarium', to: 'aquariums#show', :as => :current_aquarium

问题是你必须使用同名的路线：

aquarium GET    /aquariums/:id(.:format)    aquariums#show
aquarium GET    /aquarium(.:format)         aquariums#show

如果您进行上述更改，则当您将这些链接发送到呼叫时，第二条路线将不匹配...现在，第二条路线是匹配的，就像路线所说的那样使用您的参数作为：格式。

如果你做了这个改变，如果你故意链接到'current_aquarium'，你可能需要调整一些东西。

Rails _path助手生成路径，格式不是id
