module Mobility::Backends::Column

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 Mobility.available_locales (i.e. 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 Mobility.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.
