how to reload routes /config/routes/* in rails 4?

Question

How to force rails 4 to reload all route files?
That is without having to restart the application to make the routes from /config/routes/.rb get loaded*

Answer 1

You can use:

Rails.application.reload_routes!

You can read about it here (will have to use find)

Answer 2

config.paths["config/routes.rb"] << YOUR_ROUTE_FILE

Answer 3

In Rails 3, if you are splitting the routes.rb file into multiple files, we have to add this line to application.rb:

config.paths['config/routes'].concat Dir[Rails.root.join("config/routes/*.rb")]

...and the corresponding routes in config/routes/*.rb files like this:

TestApp::Application.routes.draw do
  namespace :api do
    resources :test
  end
end

In Rails 4, Rails no longer provides a ["config/routes"] key in Rails::Engine.paths. However, in Rails 4, there is no need to add to config.path in application.rb.

Just add the corresponding routes under config/routes/*.rb.
