Overview

Implements Mobility::Backends::Serialized backend for Sequel models, using the Sequel serialization plugin.

Examples:

Define attribute with serialized backend

class Post < Sequel::Model
  extend Mobility
  translates :title, backend: :serialized, format: :yaml
end

Read and write attribute translations

post = Post.create(title: "foo")
post.title
#=> "foo"
Mobility.locale = :ja
post.title = "あああ"
post.save
post.deserialized_values[:title]       # get deserialized value
#=> {:en=>"foo", :ja=>"あああ"}
post.title(super: true)                # get serialized value
#=> "---\n:en: foo\n:ja: \"あああ\"\n"
