`app/helpers/application_helper.rb`

	module ApplicationHelper
	def title

		base = "Sample app"

tyrotinal

	class User
		attr_accessor :name, :email
		def initialize(attributes = {})
			@name = attributes[:name]
			@email = attributes[:email]
			end
			def formatted_email
			"#{@name} <#{@email}>"
		end
	end

tyrotinal

user = User.new(:name => "Michael Hartl", :email => "[email protected]")
	user.formatted_email
