LocalizableModel

LocalizableModel allows any ActiveRecord model to have localized attributes.

Installation

Add the localizable_model gem to your Gemfile:

gem "localizable_model"

Generate the migration:

bin/rails g localizable_model:migration

Usage

You can now define localizable attributes on your model:

class Page < ActiveRecord::Base
  localizable do
    attribute :name
    attribute :body
  end
end

You can also use a dictionary. This will let you define attributes dynamically at runtime.

class Page < ActiveRecord::Base
  localizable do
    dictionary lambda { Page.localizable_attrs }
  end

  class << self
    def localizable_attrs
      [:foo, :bar, :baz]
    end
  end
end

Usage examples:

page = Page.create(locale: "en", name: "Hello")
page.name? # => true
page.name.to_s # => "Hello"

To get a localized version of a page, call .localize on it:

page = Page.first.localize("en")

.localize can also take a block argument:

page.localize("nb") do |p|
  p.locale # => "nb"
end
p.locale # => "en"

Multiple locales can be updated at the same time:

page.name = { en: "Hello", fr: "Bonjour" }

By chaining through .any_locale, you can get results from other locales if a localization is missing.

page = Page.create(locale: "fr", name: "Bonjour").localize("en")
page.any_locale.name? # => true
page.any_locale.name  # => "Bonjour"
