Challenge 1: Generate and List Routes — Solution

# config/routes.rb
Rails.application.routes.draw do
  resources :articles
end

Expected routes (from `rails routes -c articles`):

Verb    Path                        Controller#Action
GET     /articles                   articles#index
POST    /articles                   articles#create
GET     /articles/new               articles#new
GET     /articles/:id/edit          articles#edit
GET     /articles/:id               articles#show
PATCH   /articles/:id               articles#update
PUT     /articles/:id               articles#update
DELETE  /articles/:id               articles#destroy

=begin
Notes:
- index (list all) and create (make a new one) share the same path,
  /articles, distinguished only by HTTP verb (GET vs POST).
- show, update, and destroy all share /articles/:id, again distinguished
  by verb (GET, PATCH/PUT, and DELETE respectively).
- new and edit are the two "form" routes — new shows a blank form to
  create a resource, edit shows a pre-filled form to modify an existing
  one, both rendering a view rather than performing the actual database
  change themselves (create and update do that part).
- PATCH and PUT both map to the same update action — Rails accepts either
  verb for updates, with PATCH being the more semantically correct choice
  for partial updates.
