How to use globalize

In your models

  class Product < ActiveRecord::Base
    translates :name, :description, :specs
  end

Create a row and its translation:

  Locale.set_base_language('en-US')
  Locale.set('en-US')
  Product.create!(:name => 'Meatballs')
  Locale.set('es-ES')
  prod = Product.find(1)
  prod.name = 'Albóndigas'
  prod.save

Then:

  Locale.set("en-US")
  prod = Product.find(1) 
  prod.name -> "Meatballs" 
  Locale.set("es-ES")
  prod = Product.find(1) 
  prod.name -> "Albóndigas" 

In your views (or anywhere else)

  Locale.set("he-IL")
  <%= "Thanks for ordering!".t %> -> "תודה על ההזמנה!" 
  <%= "You've got %d items in your cart" / 5 %> -> "יש 5 מוצרים בסל שלך" 
  Locale.set("es-ES")
  <%= Time.now.localize("%d %B %Y") %> -> "17 Octubre 2005" 
  <%= 12345.45.localize %> -> "12.345,45"
