ruby-on-rails-3 - Rails _path 帮助程序生成格式不是 id 的路径

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

最后一次获取的原因是我的应用程序中有“当前水族馆”的概念。比如说，如果 current_aquarium 设置为 1，那么在我的 Controller 的“show”操作中，“/aquarium”将获得与“/aquariums/1”相同的渲染，代码如下

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

现在，我假设这是由于这种不同的路由，这段代码:

<%= link_to aquarium.name, aquarium %>

或

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

生成这样的路径:

/aquarium.1

我通常期望的地方:

/aquariums/1

对吗？

根据请求...这就是 rake routes | grep aquar产量:(我假设这是最后一条路线把事情搞砸了，但我本以为它会按顺序处理这些。而且，仅供引用，我最初将该路线放在顶部。将其移动到底部假设它会修复)。

Answer 1

更改最后一条路线:

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

对此:

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

问题是你必须以相同的名称命名路由:

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

如果您进行上述更改，那么当您将这些链接链接到调用时，第二条路线将不匹配...就目前而言，第二条路线是匹配的，就像路线所说的那样，它使用您的参数作为 :format。

如果您确实进行了此更改，并且有意链接到“current_aquarium”，则可能需要调整一些内容。
