Module: FriendlyId::Globalize

Defined in:
lib/friendly_id/globalize.rb

Overview

Translating Slugs Using Globalize

The Globalize module lets you use Globalize to translate slugs. This module is most suitable for applications that need to be localized to many languages. If your application only needs to be localized to one or two languages, you may wish to consider the SimpleI18n module.

In order to use this module, your model’s table and translation table must both have a slug column, and your model must set the slug field as translatable with Globalize:

class Post < ActiveRecord::Base
  translates :title, :slug
  extend FriendlyId
  friendly_id :title, :use => :globalize
end

Finds

Finds will take the current locale into consideration:

I18n.locale = :it
Post.find("guerre-stellari")
I18n.locale = :en
Post.find("star-wars")

Additionally, finds will fall back to the default locale:

I18n.locale = :it
Post.find("star-wars")

To find a slug by an explicit locale, perform the find inside a block passed to I18n’s with_locale method:

I18n.with_locale(:it) { Post.find("guerre-stellari") }

Creating Records

When new records are created, the slug is generated for the current locale only.

Translating Slugs

To translate an existing record’s friendly_id, use Model#set_friendly_id. This will ensure that the slug you add is properly escaped, transliterated and sequenced:

post = Post.create :name => "Star Wars"
post.set_friendly_id("Guerre stellari", :it)

If you don’t pass in a locale argument, FriendlyId::Globalize will just use the current locale:

I18n.with_locale(:it) { post.set_friendly_id("Guerre stellari") }
