5. ActionMailer Slanje email-a Procesiranje primljenih email-ova Wrap-a ActionController

7. ActiveRecord Object-relational mapping Bazira se na ActiveModel-u Implementira Active Record pattern
8. ActiveSupport Kolekcija utility i helper klasa Dosta proširenja Ruby jezika Jednostavno se uključuje u svaki Ruby projekat
9. ActiveJob Definiše interface za asinhrono izvršavanje zadataka u pozadini Izvršavanje dugotrajnih zadataka Odgođeno slanje mailova Novi framework u Rails 4.2
10. Railties … to bring them all and in the darkness bind them
 In the Land of Mordor where the Shadows lie Povezuje sve osnovne frameworke zajedno Rails command-line interface (rails komanda)
11. Šta možemo koristiti posebno? ActionPack ActionView ActionMailer ! ActiveModel ActiveRecord ActiveSupport ActiveJob Ratlines
12. Ruby gemovi koje Rails koristi RubyGems Bundler Rack Thor Rake Tilt Sprockets Mail
13. RubyGems gem naredba rubygems.org
15. Bundler Specifikacija dependencies-a aplikacije kroz Gemfile Prati verzije gem-ova kroz Gemfile.lock bundle komanda
16. source 'https://rubygems.org' source 'https://rails-assets.org' ruby '2.1.1' ! gem 'rails', '4.1.1' gem 'pg' gem 'haml-rails' gem 'slim-rails' gem 'draper' gem 'simple_form' gem 'reform' gem 'sanitize' gem 'html_truncator', '~> 0.2' gem 'database_cleaner' gem 'dalli', '~> 2.7' gem 'dotenv-rails', '~> 0.11' gem 'cloudinary', '~> 1.0' gem 'attachinary', '~> 1.3' gem 'rack-cache', '~> 1.2' gem 'rack-timeout' gem 'meta-tags', '~> 2.0'
17. Rack Ruby Webserver Interface Suština ActionPack-a Interface potreban da Ruby kôd reaguje na HTTP zahtjeve Kako napraviti Ruby web aplikaciju bez Railsa?
18. run ->(env) { ['200', { 'Content-Type' => 'text/html' }, ['Hello world!'] ] }
19. {"SERVER_SOFTWARE" => "thin 1.6.0 codename Greek Yogurt", "SERVER_NAME" => "localhost", "rack.input" => #<Rack::Lint::InputWrapper:0x007fa1952c54c8 @input=#<StringIO:0x007fa1952cd588>>, "rack.version" => [1, 0], "rack.errors" => #<Rack::Lint::ErrorWrapper:0x007fa1952c5450 @error=#<IO:<STDERR>>>, "rack.multithread" => false, "rack.multiprocess" => false, "rack.run_once" => false, "REQUEST_METHOD" => "GET", "REQUEST_PATH" => "/favicon.ico", "PATH_INFO" => "/favicon.ico", "REQUEST_URI" => "/favicon.ico", "HTTP_VERSION" => "HTTP/1.1", "HTTP_HOST" => "localhost:9292", "HTTP_CONNECTION" => "keep-alive", "HTTP_ACCEPT" => "*/*", "HTTP_USER_AGENT" => "Mozilla/5.0 (Macintosh; Intel Mac OS X 10_9_5) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/37.0.2062.120 Safari/537.36", "HTTP_ACCEPT_ENCODING" => "gzip,deflate,sdch", "HTTP_ACCEPT_LANGUAGE" => "en-US,en;q=0.8,de;q=0.6,hr;q=0.4,ru;q=0.2", "HTTP_COOKIE" => "", "GATEWAY_INTERFACE" => "CGI/1.2", "SERVER_PORT" => "9292", "QUERY_STRING" => "", "SERVER_PROTOCOL" => "HTTP/1.1", "rack.url_scheme" => "http", "SCRIPT_NAME" => "", "REMOTE_ADDR" => "127.0.0.1", "async.callback" => #<Method: Thin::Connection#post_process>, "async.close" => #<EventMachine::DefaultDeferrable:0x007fa1952ccf20>}
20. Thor Olakšava kreiranje CLI programa Railties koristi Thor da implementira rails naredbu Parsiranje parametara Automatski ispis informacija o korištenju
21. Rake Ruby Make Razne komponente Rails-a dolaze s vlastitim taskovima Alat za pisanje taskova u Ruby-ju Jednostavno kombinovati taskove određujući zavisnosti
22. Thor vs Rake Pisanje CLI aplikacija Lagano parsiranje argumenata ! ! Pisanje zadataka Lagano kombinovati zadatke
23. Tilt Apstrakcija za korištenje raznih template engine-a Npr. ERB, Haml, Markdown, CoffeeScript, Sass… ActionPack
24. Sprockets Kompajlira i opslužuje statičke assete (JS, CSS) Olakšava kombinovanje asseta (require)
25. Mail Olakšava generisanje, parsiranje i slanje mailova Implementiran u čistom Ruby-ju Koristi Net::SMTP, Net::POP3 isl.
