为什么我的一些Rails路径助手有一个_index后缀？ [重复]

Rails 3路由将_index附加到路由名称3个答案

I have a Rails route definition that looks something like this:

我有一个Rails路由定义，看起来像这样：

namespace :admin do
  resources :feeds
  resources :push
end

rake routes generates the following output for it:

rake routes为它生成以下输出：

admin_feeds GET  /admin/feeds  {:controller=>"admin/feeds", :action=>"index"}
admin_push_index GET  /admin/push  {:controller=>"admin/push", :action=>"index"}

Why would would the path helper for push get the _index suffix, but not feeds?

为什么push的路径助手会获得_index后缀，而不是feed？

2 个解决方案

#1

It's all based on the plurality of the resource. So if the resource name is plural, then it has no need to add an _index suffix since it's inferred.

这一切都基于多个资源。因此，如果资源名称是复数，那么它不需要添加_index后缀，因为它是推断的。

If it is a singular resource name, then it adds the suffix for clarification since admin_push would typically be a show action instead of the index action.

如果它是一个单一的资源名称，那么它会添加后缀以便澄清，因为admin_push通常是show动作而不是index动作。

You can also use

你也可以使用

resource :push

instead of

代替

resources :push

to specify a singular resource. See http://api.rubyonrails.org/classes/ActionDispatch/Routing.html

指定一个单一的资源。请参阅http://api.rubyonrails.org/classes/ActionDispatch/Routing.html
