Mongoid::Globalize
Mongoid::Globalize is based on Globalize3, but targeted at Mongoid. As Globalize3, it is compatible with and builds on the new I18n API in Ruby on Rails and adds model translations to Mongoid::Document.
Mongoid::Globalize has to work with Rails3+ and other frameworks, that supports Mongoid (Sinatra, Padrino, and others).
Requirements
Mongoid 2.3. Mongoid 2.4 and Mongoid 3 break some specs, so it’s not supported yet. Though you can use master branch of gem.
Installation
To install Mongoid::Globalize just use:
$ gem install mongoid_globalize
or, with bundler, in your Gemfile
gem 'mongoid_globalize'
Document translations
Document translations allow you to translate your document’ field values. In order to make this work, you’ll need to add include Mongoid::Globalize into your document class and define translatable fields in block of translates method, as you define usual fields. E.g.
class Post
include Mongoid::Document
include Mongoid::Globalize
translates do
field :title
field :content
field :published, type: Boolean
end
end
This allows you to translate the fields :title, :text and :published per locale:
I18n.locale = :en
post.title # => Globalize rocks!
I18n.locale = :ru
post.title # => Глобалайз рулит!
I18n fallbacks for empty translations
It is possible to enable fallbacks for empty translations. It will depend on the configuration setting you have set for I18n translations in your config.
In Rails applications, for example, you can enable them by adding the next line to config/application.rb
(or only config/environments/production.rb
if you only want them in production)
config.i18n.fallbacks = true
By default, Mongoid::Globalize will only use fallbacks when your translation model does not exist or the translation value for the item you’ve requested is nil
. However it is possible to also use fallbacks for blank
translations by adding fallbacks_for_empty_translations!
to the translates
block.
class Post
include Mongoid::Document
include Mongoid::Globalize
translates do
field :title
field :content
end
end
puts post.translations.inspect
# => [#<Post::Translation id: 1, post_id: 1, locale: "en", title: "Globalize rocks!", name: "Globalize">, #<Post::Translation id: 2, post_id: 1, locale: "nl", title: '', name: nil>]
I18n.locale = :en
post.title # => 'Globalize rocks!'
post.name # => 'Globalize'
I18n.locale = :nl
post.title # => ''
post.name # => 'Globalize'
class Post
include Mongoid::Document
include Mongoid::Globalize
translates do
field :title
field :content
fallbacks_for_empty_translations!
end
end
puts post.translations.inspect
# => [#<Post::Translation id: 1, post_id: 1, locale: "en", title: "Globalize rocks!", name: "Globalize">, #<Post::Translation id: 2, post_id: 1, locale: "nl", title: '', name: nil>]
I18n.locale = :en
post.title # => 'Globalize rocks!'
post.name # => 'Globalize'
I18n.locale = :nl
post.title # => 'Globalize rocks!'
post.name # => 'Globalize'
Scoping objects by those with translations
To only return objects that have a translation for the given locale we can use the `with_translations` scope. This will only return records that have a translations for the passed in locale.
Post.with_translations('en') # => [#<Post::Translation id: 1, post_id: 1, locale: "en", title: "Globalize rocks!", name: "Globalize">, #<Post::Translation id: 2, post_id: 1, locale: "nl", title: '', name: nil>]
Post.with_translations(I18n.locale) # => [#<Post::Translation id: 1, post_id: 1, locale: "en", title: "Globalize rocks!", name: "Globalize">, #<Post::Translation id: 2, post_id: 1, locale: "nl", title: '', name: nil>]
Post.with_translations('de') # => []
