What is this gotcha inRails application.routes.recognize_path when using the root path of a mounted engine?












0















I am developing an engine and I need to programmatically find which controller action will be used for any path of either the host app or my engine. However, there seems to be a gotcha when resolving the root PATH of an engine.



The dummy's routes file is:



Rails.application.routes.draw do
mount Authz::Engine => '/authz', as: :authz
#...
end


The engine's routes file is:



Authz::Engine.routes.draw do
root 'home#index'
resources :foos
#...
end


Somewhere in the main app I am doing the following I don't understand what is the gotcha here...



Rails.application.routes.recognize_path authz.root_path, method: :get
# => No route matches "/authz"


Strangely if I do the following, I get the correct answer.



Rails.application.routes.recognize_path authz.root_url, method: :get
# => {:controller=>"authz/home", :action=>"index"}
