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

最后得到的原因是我的应用程序中有“当前水族馆”的概念。例如，如果current_aquarium设置为1，则在我控制器的“显示”操作中，“ / aquarium”与“ / aquariums / 1”具有相同的呈现方式，且代码如下

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

现在，我假设这归功于这种不同的路由，此代码：

<%= link_to aquarium.name, aquarium %>

要么

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

生成这样的路径：

/aquarium.1

我通常期望的位置：

/aquariums/1

对？

每个请求...产生的结果是rake routes | grep aquar：（我假设这是最后一条弄乱了事情的路线，但我以为它将按顺序处理这些路线。而且，仅供参考，我最初在假设它可以修复，则将其移至底部）。

Answer 1

从此更改最后一条路线：

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

对此：

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

问题是您必须路由名称相同的东西：

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

如果您在上面进行更改，则当您将这些链接链接到调用时，第二条路由将不匹配...就目前而言，第二条路由是匹配的，就像该路由所说的将您的参数用作：format一样。

如果您确实进行了更改，那么如果您有意链接到“ current_aquarium”，则可能需要进行一些调整。
