Rails _path helper生成格式为非id的路径

Question

在我的路由。我有:

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

最后一个get的原因是我在我的应用程序中有"当前水族馆"的概念。如果，说，current_aquarium被设置为1，那么在我的控制器的"show"操作中，"/aquarium"获得与"/aquarium/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:

/aquariums/1

对吧?

每个请求

…以下是rake routes | grep aquar的收益率:(我假设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。仅供参考，我本来是把这条路线建在山顶上的。把它移到底部，假设它会修复)。

Answer 1

将最后一条路由改为:

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

:

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

问题是你必须给路由命名相同的东西:

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

如果你做了上面的改变，那么第二个路由将不匹配当你做那些链接到调用…现在，第二个是匹配的，就像路由说的那样，它正在使用你的参数作为:格式。

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