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.
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 in postgres is via the postgres array
To add the array to the model the migration looks like this
class CreateMyModel < ActiveRecord::Migration def change create_table :my_model do |t| t.string_array :locales end end end
If your database does not support native array types you can use ActiveRecords ability to serialize the locales array
class MyModel < ActiveRecord::Base serialize :locales translate :name end
And add the column as a string
class CreateMyModel < ActiveRecord::Migration def change create_table :my_model do |t| t.string :locales end end end
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 there is a dummy app setup in the spec directory. Since the example is using postgres, to get the tests working there needs to be a setup postgres user with the needed rights.
$ createuser -h localhost Enter name of role to add: translatable Shall the new role be a superuser? (y/n) n Shall the new role be allowed to create databases? (y/n) y Shall the new role be allowed to create more new roles? (y/n) n
Move the the database.yml into place and edit to your needs, and setup the test database
$ rake setup:database_config $ rake setup:test_database
Now the test can be run via
$ rake spec
The gem is still in early development and has just been extracted from a project. So any bug reports and contributions are highly welcome.
