Meta Field

Ruby On Rails serialization gem that supports ActiveModel::Dirty interface to track changes.

Usage

1. Have a meta column in the database table

class AddMetaToRecords < ActiveRecord::Migration
  def change
    add_column :records, :meta, :text, limit: 1.megabyte - 1
  end
end

2. Declare which fields are serialized in meta column

class Record < ActiveRecord::Base
  has_meta_fields :field1, :field2

end

3. Use field1 setter and getter as it is a regular record attribute.

record = Record.new field1: 'value1'
record.field1 # => 'value1'
record.field1 = 'value2' # => 'value2'
record.save # saved to `meta` column as { 'field1' => 'value2' }
