14. Convention over Configuration
15. DRY (Don’t Repeat Yourself)
16. Projet : MyNotes
17. Projet : MyNotes $ rails new MyNotes • Créer un nouveau projet $ cd MyNotes $ rails server • Démarrer le serveur
19. View Controller Model Routing
21. CRUD
22. Create Read Update Delete CRUD
23. Ressource : notes notes notes id integer title varchar content text
24. $ rails generate scaffold note title content:text invoke active_record create db/migrate/20130130171611_create_notes.rb create app/models/note.rb invoke test_unit create test/unit/note_test.rb create test/fixtures/notes.yml invoke resource_route route resources :notes invoke scaffold_controller create app/controllers/notes_controller.rb invoke erb create app/views/notes create app/views/notes/index.html.erb create app/views/notes/edit.html.erb create app/views/notes/show.html.erb create app/views/notes/new.html.erb create app/views/notes/_form.html.erb ... Génération du CRUD

28. Migration class CreateNotes < ActiveRecord::Migration def change create_table :notes do |t| t.string :title t.text :content t.timestamps end end end db/migrate/20130130175117_create_notes.rb $ rake db:migrate
29. Base de données notes notes id integer title varchar content text
31. Modèle
32. View Controller Model Routing
33. Modèle class Note < ActiveRecord::Base end app/models/note.rb
34. Modèle : création Note.create(content: "I created Ruby", title: "Matz")
35. Modèle : mise à jour note = Note.find(1) note.content = "I love Ruby" note.save
36. Modèle : lecture Note.where(:title => "Matz").order("title ASC").limit(5)
37. Modèle : suppression Note.find(1).destroy
38. Vue
39. View Controller Model Routing
40. ERB <p> <b>Title:</b> <%= @note.title %> </p> <p> <b>Content:</b> <%= @note.content %> </p> app/views/notes/show.html.erb
41. Formulaires <%= form_for(@note) do |f| %> <%= f.label :title %> <%= f.text_field :title %> <%= f.label :content %> <%= f.text_area :content %> <%= f.submit %> <% end %>
42. Contrôleur
43. View Controller Model Routing
44. Contrôleur class NotesController < ApplicationController def show @note = Note.find(params[:id]) end end app/controllers/notes_controller.rb app/views/notes/show.html.erb Request GET /notes/1 <p> <b>Title:</b> <%= @note.title %> </p>
