Ruby on Rails Tutorial, Michael Hartl Chapter 2

In the toy_app exercise https://www.railstutorial.org/book/toy_app I'm having a problem changing the default message displayed when running the application from the generic : "Welcome aboard, you're riding ruby on rails" to "hello, world!" by routing the page to the hello method in the application_controller file. This is what i have in controller/application_controller:

  Rails.application.routes.draw do
  # Prevent CSFR attacks by raising an exception.
  # For API's, you may want to use :null_session instead
  protect_from_forgery with: :exception

  def hello
    render text: "hello, world!"
  end

end

and in locales/routes.rb 

    Rails.application.routes.draw do

  # The priority is based upon order of creation: first created -> highest priority.
  # See how all your routes lay out with "rake routes".

  # You can have the root of your site routed with "root"
  root 'application#hello'

  # Example of regular route:
  #   get 'products/:id' => 'catalog#view'

  # Example of named route that can be invoked with purchase_url(id: product.id)
  #   get 'products/:id/purchase' => 'catalog#purchase', as: :purchase

  # Example resource route (maps HTTP verbs to controller actions automatically):
  #   resources :products

  # Example resource route with options:
  #   resources :products do
  #     member do
  #       get 'short'
  #       post 'toggle'
  #     end
  #
  #     collection do
  #       get 'sold'
  #     end
  #   end

  # Example resource route with sub-resources:
  #   resources :products do
  #     resources :comments, :sales
  #     resource :seller
  #   end

  # Example resource route with more complex sub-resources:
  #   resources :products do
  #     resources :comments
  #     resources :sales do
  #       get 'recent', on: :collection
  #     end
  #   end

  # Example resource route with concerns:
  #   concern :toggleable do
  #     post 'toggle'
  #   end
  #   resources :posts, concerns: :toggleable
  #   resources :photos, concerns: :toggleable

  # Example resource route within a namespace:
  #   namespace :admin do
  #     # Directs /admin/products/* to Admin::ProductsController
  #     # (app/controllers/admin/products_controller.rb)
  #     resources :products
  #   end
end

In application_controller.rb, replace Rails.application.routes.draw do with class ApplicationController < ActionController::Base. It looks like this line was inadvertently replaced with a copy of the first line from routes.rb.

Assuming you have a template like app/views/layouts/application.html.erb defined, you should be good to go.

You should only put routes in your route file.

You don't want to put methods in there.

Try storing your methods in the controlle
