rails 资源路由中的默认段名称

问题描述

我想在我的 rails 应用程序中创建一条路线

I want to create a route in my rails application along the lines of

/panda/blog
/tiger/blog
/dog/blog

熊猫、老虎和狗都是永久链接(对于动物类)

where panda, tiger, and dog are all permalinks (for an animal class)

通常的做法

map.resources :animals do |animal|
 animal.resource :blog
end

将沿着

/animals/panda/blog
/animals/tiger/blog
/animals/dog/blog

但我不想要第一段，因为它总是一样的.

But i do not want the first segment, as it will always be the same.

我知道我可以通过手动路由来做到这一点，但我想知道如何使用 rails 资源，因为拥有动物和博客是我的要求.

I know I could do this by manual routing, but I want to know how to do using rails resources, as having animals and blogs is a requirement for me.

推荐答案

在 rails 3.x 中，可以添加 path =>"" 到任何 resource 或 resources 调用以从生成的路径中删除第一段.

In rails 3.x, you can add path => "" to any resource or resources call to remove the first segment from the generated path.

resources :animals, :path => ""

$ rake routes

    animals GET    /                   {:action=>"index", :controller=>"animals"}
            POST   /                   {:action=>"create", :controller=>"animals"}
 new_animal GET    /new(.:format)      {:action=>"new", :controller=>"animals"}
edit_animal GET    /:id/edit(.:format) {:action=>"edit", :controller=>"animals"}
     animal GET    /:id(.:format)      {:action=>"show", :controller=>"animals"}
            PUT    /:id(.:format)      {:action=>"update", :controller=>"animals"}
            DELETE /:id(.:format)      {:action=>"destroy", :controller=>"animals"}
