Ruby on Rails?

A web framework that's optimized for
programmer happiness and sustainable
productivity.

It lets you write beautiful code by
favoring convention over configuration.

MVC

24. Exemplo
Imagine que eu precise gerenciar
usuários, estes teriam apenas nome e
e-mail.

25. Instala a gem rails
$ gem install rails
$ rails new meu_projeto
Cria um novo projeto

26. $ cd meu_projeto
$ rails g model usuario nome:string
email:string

27. class CreateUsuarios < ActiveRecord::Migration
def self.up
create_table :usuarios do |t|
t.string nome
t.string email
t.timestamps
end
dnd
def self.down
drop_table :usuarios
end
end
Migration

28. $ rake db:migrate
Migration

29. Model
class Usuario < ActiveRecord::Base
end
app/models/usuario.rb

31. Model
u.save?() Usuario.all
u.update_attributes() Usuario.last(5)
u.destroy() Usuario.find(12)
u.valid?() Usuario.new
u.errors Usuario.query
u.new_record? Usuario.first()
u.meu_atributo_x
E muito mais...

32. Controller
class UsuariosController < ApplicationController
def index
@usuarios = Usuario.all
end
end
app/controllers/usuarios_controller.rb

33. View
<ul>
<% @usuarios.each do |u| %>
<%= u.nome %>
<% end %>
</ul>
Action
