Module: Mobility::Backend::Serialized

Includes:
OrmDelegator
Defined in:
lib/mobility/backend/serialized.rb

Overview

Stores translations as serialized attributes in a single text column. This implies that the translated values are not searchable, and thus this backend is not recommended unless specific constraints prevent use of other solutions.

To use this backend, ensure that the model table has a text column on its table with the same name as the translated attribute.

Backend Options

format

Format for serialization. Either :yaml (default) or :json.
