module Mobility
  module Backends
=begin

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.
