Agile Web Development with Rails 6: Iteration K1 Setting the Locale note about routes (pdf 259)

This isn’t an error in the text, but it’s a good teaching opportunity.

In the section where you add the scope ‘(:locale)’ to routes.rb, the text should note that this must be at the very bottom of your routes.rb file or else any resources after it will not route to the correct controller. It’s implicit in the code example, but should be called out in the text because it’s a common ‘gotcha’ and an easy mistake to make. You also need to take a look any time you generate a new resource to make sure it is above the scope ‘(:locale)’ block

  # GOOD: This is what you need to do
  # All other routes
  resources :products do
    get :who_bought, on: :member
  end
  
  scope '(:locale)' do
    resources :orders
    resources :line_items
    resources :carts
    root 'store#index', as: 'store_index'
  end
end
# end of routes file

  # BAD: You will never see your products page again
  
  scope '(:locale)' do
    resources :orders
    resources :line_items
    resources :carts
    root 'store#index', as: 'store_index'
  end
  resources :products do
    get :who_bought, on: :member
  end

end
# end of routes file
