Rails中的路径解析 [英] Path parsing in rails

问题描述

我正在寻找解析这样的路由路径的方法:

I am looking for method for parsing route path like this:

ActionController::Routing.new("post_path").parse
#=> {:controller => "posts", :action => "index"}

它应该与url_for

更新
我发现:

Upd
I've found out: What is the opposite of url_for in Rails? A function that takes a path and generates the interpreted route?

ActionController::Routing::Routes.recognize_path("/posts")

所以现在我需要将posts_path转换为"/posts"

So now I need to convert posts_path into "/posts"

推荐答案

有此方法:

>> ActionController::Routing::Routes.recognize_path("/posts/")
=> {:action=>"index", :controller=>"posts"}

如果您的路线只有一个字符串(例如"posts_path")，那么我想在您正在使用的上下文中，您应该能够做到

If you only have a string with your route (like "posts_path"), then I guess in the context you're using this you should be able to do

ActionController::Routing::Routes.recognize_path(send("posts_path".to_sym))

顺便说一句，这也对我有教育意义:)

btw this was educating for me too :)
