Overview

ActiveRecord attribute type for a PostgreSQL hstore i18n column.

hstore is a flat String => String map, so each translation is stored under the key ".", e.g. "de.name" => "Science-Fiction". In Ruby the gem works with the nested Hash {name: "Science-Fiction"}. Reading and writing the hstore text format is delegated to ActiveRecord's own hstore type.
