Ruby on Rails - 将URL映射到控制器，方法和参数

Question

I know that the file routes.rb in a Rails application maps a URL to a controller, a method, and a set of parameters in the params hash. This is complicated somewhat by "resources", nested resources, and non-RESTful routes.

Is there a way to run a command on the rails console to map a URL and figure out exactly which controller, which method, which http method(s), and the exact value of a parameter hash from a given URL?

Is it then possible to then run the controller method with the parameters hash on the rails console and get the output of the controller sent to STDOUT? If so, how?

Answer 1

Try these

Rails.application.routes.named_routes.each{|p,s| puts p,s} 
Rails.application.routes.url_helpers.my_path_helper   # To get url for a path helper

or

route = Rails.application.routes
route.recognize_path "/poweruser/3"           # will give you result exactly you wanted 

Answer 2

try it with running

bundle exec rake routes

Rails.application.routes.recognize_path
