Rails 2.3.5：如何获取路线名称 [英] Rails 2.3.5: how to get routes name

问题描述

在我的应用程序route.rb中，我定义了以下三种路由

  map.signup'/ signup',：控制器=> ‘用户’，：action => 'new'
 map.login'/ login'，：controller => 会话，：action => ‘new’
 map.logout‘/ logout’，：controller => 会话，：action => 'destroy'
  

我是否可以获取特定路径的控制器和动作名称？ / p>

我正在寻找这样的方法...

  def current_routes（a）
结束
  

应返回：controller => ; ‘用户’，：action => 'new'如果我调用 current_routes（'signup_path'）

解决方案

像这样

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

如果您的路由中只有一个字符串（例如 signup_path），那么我想在上下文中您应该使用能够做到

 
 ActionController :: Routing :: Routes.recognize_path（send（ signup_path .to_sym））
 
 

In my applications routes.rb I have defined three routes like the following

 map.signup '/signup', :controller => 'users', :action => 'new'
 map.login  '/login', :controller => 'sessions', :action => 'new'
 map.logout '/logout', :controller => 'sessions', :action => 'destroy'

Is it possible for me to get the controller and action name for a particular path?

I am looking for some method like this...

def current_routes(a)
end

should return :controller => 'users', :action => 'new' if I call current_routes('signup_path')

解决方案

Try like this

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

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

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