以多个 id 作为参数的 Rails 3 自定义路由 [英] Rails 3 Custom Route that takes multiple ids as a parameter

问题描述

如何向我的 Rails 3 应用程序添加路由，以便我拥有一个映射到接受多个参数的 RESTful 资源中的操作的 URL:

How do I add a route to my Rails 3 app which allows me to have a URL that maps to an action in a RESTful resource that accepts multiple parameters:

/modelname/compare/1234,2938,40395

然后在我的控制器中，我想访问这些 ID:

And then in my controller, I want to access these ids:

@modelname = Modelname.find(params[:modelname_ids])

到目前为止，我一直在尝试匹配 '/modelname/compare/:modelname_ids', :to =>'modelname#compare'，但我不断收到 No route matching "/modelname/compare/4df632fd35be357701000005,4df632fd35be357701000005".有什么建议吗?

So far, I have been trying match '/modelname/compare/:modelname_ids', :to => 'modelname#compare', but I keep getting No route matches "/modelname/compare/4df632fd35be357701000005,4df632fd35be357701000005". Any suggestions?

推荐答案

你可以设置一个匹配任何东西的路由，然后在你的控制器中拆分参数:

You can setup a route that matches anything, then split the parameter inside your controller:

resources :modelname do
  match 'compare/*path' => 'controller#compare_action'
end

# controller:
def compare_action
  @modelname = Modelname.find(params[:path].split(','))
end
