Module: Sequel::Plugins::SerializationModificationDetection

Defined in:

lib/sequel/plugins/serialization_modification_detection.rb

Overview

Sequel’s built in Serialization plugin doesn’t check for modification of the serialized objects, because it requires an extra deserialization of a potentially very large object. This plugin can detect changes in serialized values by checking whether the current deserialized value is the same as the original deserialized value. This does require deserializing the value twice, but the original deserialized value is cached.

Example

require 'sequel'
require 'json'
class User < Sequel::Model
  plugin :serialization, :json, :permissions
  plugin :serialization_modification_detection
end
user = User.create(:permissions => {})
user.permissions[:global] = 'read-only'
user.save_changes
