Module: Mobility::Backends::Column

Extended by:
Mobility::Backend::OrmDelegator
Included in:
ActiveRecord::Column, Sequel::Column
Defined in:
lib/mobility/backends/column.rb

Overview

Stores translated attribute as a column on the model table. To use this backend, ensure that the model table has columns named <attribute>_<locale> for every locale in I18n.available_locales.

If you are using Rails, you can use the mobility:translations generator to create a migration adding these columns to the model table with:

rails generate mobility:translations post title:string

The generated migration will add columns title_<locale> for every locale in I18n.available_locales. (The generator can be run again to add new attributes or locales.)

==Backend Options

There are no options for this backend. Also, the locale_accessors option will be ignored if set, since it would cause a conflict with column accessors.
