Recognize routes in rails console Session

Solution 1:

There is a good summary with examples at Zobie's Blog showing how to manually check URL-to-controller/action mapping and the converse. For example, start with

 r = Rails.application.routes

to access the routes object (Zobie's page, a couple years old, says to use ActionController::Routing::Routes, but that's now deprecated in favor of Rails.application.routes). You can then check the routing based on a URL:

 >> r.recognize_path "/station/index/42.html"
 => {:controller=>"station", :action=>"index", :format=>"html", :id=>"42"}

and see what URL is generated for a given controller/action/parameters combination:

 >> r.generate :controller => :station, :action=> :index, :id=>42
 => /station/index/42

Thanks, Zobie!

Solution 2:

In the console of a Rails 3.2 app:

# include routing and URL helpers
include ActionDispatch::Routing
include Rails.application.routes.url_helpers

# use routes normally
users_path #=> "/users"
