Make attributes of an ActiveRecord Model translatable, and store the translations in the provided I18n backend. This is really helpful if there already is, a interface to provide ie missing translations for elements in I18n.
Add
gem"activerecord_translatable"
to your gemfile, this should work for rails 3 and above.
Use inside of the model
class MyModel < ActiveRecord::Base translate :title end I18n.locale = :en mymodel = MyModel.create(title: "My title", title_de: "Mein Title) mymodel.title_wk = "Woohhaakkk" mymodel.title # => "My title" mymodel.title_en # => "My title" mymodel.title_wk # => "Woohhaakkk"
To save the locales ActiveRecordTranslatable saves an array of the specified locale, for this to work, the database needs the ability to save arrays. The easiest way to handle this is to use ActiveRecords ability to serialize.
classMyModel<ActiveRecord::Baseserialize:localestranslate:nameend
And add the column as a string
classCreateMyModel<ActiveRecord::Migrationdefchangecreate_table:my_modeldo|t|t.string:localesendendend
If you are using postgres you can also use the native postgres array
gem'activerecord-postgres-array'
To add the array to the model the migration looks like this
classCreateMyModel<ActiveRecord::Migrationdefchangecreate_table:my_modeldo|t|t.string_array:localesendendend
And the model does not need to know anything about this
classMyModel<ActiveRecord::Basetranslate:nameend
Translateable saves the translation via I18n.backend.store_translations, this means that the backend has to be able to store new items. So backend needs to be for example the KeyValue or ActiveRecord one. More railscasts.com/episodes/256-i18n-backends
The tests are using rspec and an im memory sqlite database, so all that is needed is to run
$ rake spec
This has been extracted form an Rails application so it should be pretty stable by now. Any contributions and fixes are of course highly welcome!
