5. How Rails has changed the web
6. Startup environment
7. Agile movement Dave Thomas Martin Fowler
9. Continuos integration
10. On Rails way • Convention over configuration • Don’t repeat yourself (DRY) • Implicit instead of explicit • Opinionated
11. Convention over configuration
12. > rails g scaffold User name:string age:integer enabled:boolean
13. invoke active_record create db/migrate/create_users.rb create app/models/user.rb invoke test_unit create test/models/user_test.rb create test/fixtures/users.yml invoke resource_route route resources :users invoke scaffold_controller create app/controllers/users_controller.rb invoke erb create app/views/users create app/views/users/index.html.erb create app/views/users/edit.html.erb create app/views/users/show.html.erb create app/views/users/new.html.erb create app/views/users/_form.html.erb invoke test_unit create test/controllers/users_controller_test.rb create test/system/users_test.rb
14. invoke active_record create db/migrate/create_users.rb create app/models/user.rb invoke test_unit create test/models/user_test.rb create test/fixtures/users.yml
15. invoke resource_route route resources :users
16. invoke scaffold_controller create app/controllers/users_controller.rb invoke erb create app/views/users create app/views/users/index.html.erb create app/views/users/edit.html.erb create app/views/users/show.html.erb create app/views/users/new.html.erb create app/views/users/_form.html.erb invoke test_unit create test/controllers/users_controller_test.rb create test/system/users_test.rb
17. class User < ActiveRecord::Base end
18. User.create!(name: 'Rodrigo', age: 22, enabled: true) User.first.name => "Rodrigo"
19. Rails.application.routes.draw do resources :users end
20. class Post < ActiveRecord::Base has_many :comments belongs_to :author enum status: %i[draft review published] end
21. post = Post.first post.draft? post.author_id
22. Convention over configuration • Table name is plural • Primary key is called id • Column names are instance attributes
23. Assets pipeline • Merge all files • Minification and compression • Transpiling
25. Tooling
27. RuboCop rules • Class length • Methods length • Parameters list • Unused variable • Indentation
38. Inspirations
39. Conclusion • Don't reinvent the wheel • Funny language • Plug and play
