Rails.application.routes list all routes and determine controller

Question

I am trying to write a script that can list all available routes and for each route, query the controller and action name (a bit like rake routes).

If I run Rails.application.routes.routes I can see the data is all there. I just can't seem to access it.

 @named_routes=
  {"root"=>
    #<ActionDispatch::Journey::Route:0x007fc2cb40a598
     @app=
      #<ActionDispatch::Routing::RouteSet::Dispatcher:0x007fc2cb40b448
       @controller_class_names=#<ThreadSafe::Cache:0x007fc2cb40b420 @backend={}, @default_proc=nil>,
       @defaults={:trailing_slash=>false, :controller=>"home", :action=>"show"},
       @glob_param=nil>,
     @constraints={:required_defaults=>[:trailing_slash, :controller, :action], :request_method=>/^GET$/},
     @decorated_ast=nil,
     @defaults={:trailing_slash=>false, :controller=>"home", :action=>"show"},

How do I access that hash tucked away in there with the controller name.

As a side, Is there a way to determine a path from this?

This should work if I understand your question correctly:

Rails.application.routes.routes.named_routes.values.map(&:defaults)

Then you can do something like this:

Rails.application.routes.routes.named_routes.values.map do |route|
  "#{route.defaults[:controller]}#{route.defaults[:action]}"
end

For rails 5 it has slightly changed. I used this to get all routes Rails.application.routes.named_routes.send(:routes).values
