Defined in:
lib/acta/types/model.rb

Overview

Wraps an Acta::Model subclass (or any class with ‘to_acta_hash` / `from_acta_hash`, e.g. AR classes that include Acta::Serializable) so it can be used as an `attribute` type on another Acta::Model. The wrapping is automatic — `attribute :location, GeoPoint` invokes this internally; consumers don’t construct it directly.
