Mongoid::I18n is a gem that makes localization almost transparent for the developer.
First, include it in your Gemfile. Remeber to add the :require parameter:
gem 'mongoid_i18n', :require => 'mongoid/i18n'
Now you can add the module to the documents that need localization:
class Entry include Mongoid::Document include Mongoid::I18n localized_field :title # Just use localized_field instead of field field :published, :type => Boolean end
This will allow you to do stuff like this:
I18n.locale = :en @entry = Entry.new(:title => 'Title') # will be stored in the 'en' translation I18n.locale :es @entry.title = 'Título' # will be stored in the 'es' translation @entry.title_translations # this returns a hash: {'en' => 'Title', 'es' => 'Title'} @entry.title_translations = {'en' => 'New title', 'es' => 'Nuevo título} # You can always mass-assign.
The localized_field helper has two options (setted to false as default): – credits to @nicolaracco (github.com/nicolaracco/mongoid_localizable) localized_field :title, :clear_empty_values => true # This will remove all blank values when you do a mass assignment localized_field :title, :use_default_if_empty => true # This will return the value assigned to the default locale, if there isn’t a value for the current locale
localized_field :title, :clear_empty_values => true, :use_default_if_empty => true # When you do mass assignment, empty values are removed. If you try to get a ‘removed’ value, it will return the default value
With the last case: @entry.title_translations = { ‘en’ => ‘New title’, ‘es’ => ” } # It will store only the ‘en’ value @entry.title_translations # => New title
There are validation helper to manage locale fields: – credits to @nicolaracco (github.com/nicolaracco/mongoid_localizable) validates_default_locale :title # The field has to contain at least the default translation validates_one_locale :title # The field has to contain at least one translation validates_all_locales :title # The field has to contain a translation for each available locale
Criteria is handled for you:
I18n.locale = :en Entry.where(:title => 'Title') # This will search automatically for the 'en' translation Entry.find(:first, :title.in => ['Stuff', 'More stuff']) # find() and complex criteria also works
-
Fork the project.
-
Make your feature addition or bug fix.
-
Add tests for it. This is important so I don’t break it in a future version unintentionally.
-
Commit, do not mess with rakefile, version, or history. (if you want to have your own version, that is fine but bump version in a commit by itself I can ignore when I pull)
-
Send me a pull request. Bonus points for topic branches.
