如何找到Rails中的当前路线？ [英] How can I find out the current route in Rails?

问题描述

我需要在Rails的过滤器中了解当前路线。我怎么知道它是什么？

I need to know the current route in a filter in Rails. How can I find out what it is?

我正在做REST资源，看不到命名路由。

I'm doing REST resources, and see no named routes.

推荐答案

要查找URI：

current_uri = request.env['PATH_INFO']
# If you are browsing http://example.com/my/test/path, 
# then above line will yield current_uri as "/my/test/path"

要找出路线，即控制器，动作和参数：

To find out the route i.e. controller, action and params:

path = ActionController::Routing::Routes.recognize_path "/your/path/here/"

# ...or newer Rails versions:
#
path = Rails.application.routes.recognize_path('/your/path/here')

controller = path[:controller]
action = path[:action]
# You will most certainly know that params are available in 'params' hash
