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？
我正在做REST资源，看不到命名路由。
最佳答案
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 Controller ， Action 和参数:
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
