Why ruby on rails
This document discusses the features and benefits of Ruby on Rails, an open-source web application development framework written in Ruby. It highlights how Rails provides full CRUD functionality out of the box, handles database operations through Active Record, and includes tools for authorization, authentication, asset compilation, and testing. The document also provides code samples for common Rails tasks like migrations, models, and controllers to demonstrate its capabilities.
Why ruby on rails
- 2. Don't wait forthe "Questions?" slide
- 4. Boris Dinkevich CEOof 500Tech hackademy.co.il meetup.com/AngularJS-IL Among our clients: - Wix - Cellebrite - Autodesk - ...
- 5. A Web developmentframework based on the Ruby programming language The Zend to PHP The Spring to Java The ASP.NET to #C
- 6.
- 7. Scalable ? Performant? Development speed ?
- 9. C++ ? Caching Optimizations Parallelizm caches_page :index def index # Generate Item's index page end All available items: <ul> <li> </li> </ul>
- 11. Quality over quantity Full tests Platform integration Ready for everything
- 14. > Item.active.first.user.name 'Boris' class Item < ActiveRecord::Base belongs_to :user validates :desc, presence: { message: 'Please fill this out' }, length: { minimum: 4, maximum: 255 } scope :active, lambda { where(state: 'active') } has_paper_trail end Sample test The code
- 15. > User.create(email: 'boris@500tech.com',name: 'Boris') true > User.where(created_at: [1.week.ago..Date.today]).count 102 > User.verified.last.items.count 1 > User.pluck(:email) ['boris@500tech.com', 'adam@500tech.com', ...]
- 16. No DDL NoSQL "scripts" Same for every developer Same for production class AddEmailToUsers < ActiveRe cord::Migration def up add_column :users, :email, :text add_index :users, :email end def down remove_column :users, :email remove_index :users, :email end end
- 17. Authorization Authentication GlueDB to HTML
- 19. Full CRUD controller Index, Show, Edit, Create, New, Update, Destroy def index @items = Item.all() end def show @item = Item.find(params[:id]) end def create @item = Item.new(params[:id]) if @item.save() .... class ItemsController < InheritedResources::Base end
- 20. Now with XMLand JSON support class ItemsController < InheritedResources::Base respond_to :html, :xml, :json end |- app Directory structure |- views |- items |- index.html.erb |- show.html.erb |- index.json.jbuilder |- show.xml.erb
- 21. Now with Authorizationand Authentication def index @items = Items.all end def index @items = @current_user.items.all end class ItemsController < InheritedResources::Base respond_to :html, :xml, :json protected def begin_of_association_chain @current_user end end Secure:
- 22. HAML SLIM Partials JSON Builder XML Builder PDF Builder etc
- 23. Compile CoffeeScript CompileSASS/LESS Minify JavaScript Minify CSS Version JS & CSS
- 24. describe 'create' do before do post(:create, params) end context 'missing username' do let(:params) { { username: '', password: 'somepass' } } it { expect(response.status).to eq(400) } it { expect(response.body).to eq('Missing credentials') } end end
- 25. VCR describe "create",vcr: { cassette_name: "facebook-login" } do Faker before do post(:create, params) end ... > Faker::Internet.email "eliza@mann.net" > Faker::Avatar.image "http://robohash.org/sitsequiquia.png?size=300x300"
