Question

ruby on rails的新手，尝试获取此url结构：

/about
/about/staff
/about/contact
/about/brazil
/about/brazil/staff
/about/brazil/contact

当我这样做时：

rails generate controller about index
rails generate controller about staff
rails generate controller about contact

我将路线设置为：

get "about", :to => "about#index"
get "about/staff", :to => "about#staff"
get "about/contact", :to => "about#contact"

一切都很好，但是当我需要为巴西办公室的第三级做同样的事情时我感到难过

我应该做什么

rails generate controller about brazil_index
rails generate controller about brazil_staff
rails generate controller about brazil_contact

get "about/brazil", :to => "about#brazil_index"
get "about/brazil/staff", :to => "about#brazil_staff"
get "about/brazil/contact", :to => "about#brazil_contact"

或者有更简洁的方法来实现这一目标吗？

Answer 1

我想你想称之为rails generate controller About index staff contact

通过三项操作AboutController，index和staff生成contact。然后你想允许传入id参数作为第二个路径元素：

然后在config/routes.rb：

  get "about/index"
  get "about/staff"
  get "about/contact"
  get "about/:id/index" => 'about#index'
  get "about/:id/staff" => 'about#staff'
  get "about/:id/contact" => 'about#contact'

当我查看rake routes的路线时，我现在看到了：

$ rake routes
  about_index GET /about/index(.:format)       {:controller=>"about", :action=>"index"}
  about_staff GET /about/staff(.:format)       {:controller=>"about", :action=>"staff"}
about_contact GET /about/contact(.:format)     {:controller=>"about", :action=>"contact"}
              GET /about/:id/index(.:format)   {:controller=>"about", :action=>"index"}
              GET /about/:id/staff(.:format)   {:controller=>"about", :action=>"staff"}
              GET /about/:id/contact(.:format) {:controller=>"about", :action=>"contact"}

您现在可以请求http://localhost:3000/about/brazil/staff，并且params [：id]的值将是“brazil”。

一个很好的选择是在/config/routes.rb文件中使用'命名空间'分隔路径，如下所示：

namespace :about do
  match '/' => 'about#index'
  match '/staff' => 'about#staff'
  match '/contact' => 'about#contact'
  match '/:country/staff' => 'about#staff'
  match '/:country/contact' => 'about#contact'
end

如果您随后运行rake routes，则可以看到产生的路由：

/about(.:format)                  {:controller=>"about/about", :action=>"index"}
/about/staff(.:format)            {:controller=>"about/about", :action=>"staff"}
/about/contact(.:format)          {:controller=>"about/about", :action=>"contact"}
/about/:country/staff(.:format)   {:controller=>"about/about", :action=>"staff"}
/about/:country/contact(.:format) {:controller=>"about/about", :action=>"contact"}

所以这些都路由到同一个控制器（我相信你想要的），而你只有三个动作：staff，index和contact。如果:country值存在于网址中，则params[:country]值将作为参数传入，并将作为{{1}}进行访问。

这是你想要做的吗？
