Add "resources :articles" to routes.rb

Afterwards, ran rake routes:

learnrails@localhost:~/rails/blog ;-) rake routes
      Prefix Verb   URI Pattern                  Controller#Action
    articles GET    /articles(.:format)          articles#index
             POST   /articles(.:format)          articles#create

             PATCH  /articles/:id(.:format)      articles#update
             PUT    /articles/:id(.:format)      articles#update
             DELETE /articles/:id(.:format)      articles#destroy
        root GET    /                            welcome#index

Run "rails generate controller articles"

Output:
learnrails@localhost:~/rails/blog ;-) rails generate controller articles
      create  app/controllers/articles_controller.rb
      invoke  erb
      create    app/views/articles
      invoke  test_unit
      create    test/controllers/articles_controller_test.rb
      invoke  helper
      create    app/helpers/articles_helper.rb
      invoke    test_unit
      create      test/helpers/articles_helper_test.rb
      invoke  assets
      invoke    coffee
      create      app/assets/javascripts/articles.js.coffee
      invoke    scss
      create      app/assets/stylesheets/articles.css.scss
learnrails@localhost:~/rails/blog ;-)
Add empty "new" method

  def new
  end
Create new file app/views/articles/new.html.erb
Ignore ~ files
Add "url: articles_path" to form_for

The above changes the action of the form from articles/new to
/articles, which the routes know how to handle when action is POST
Add create method to articles controller
Display the params from the articles form
