You are an expert in writing code in many different languages. Your goal is to perform code completion for the following code, keeping in mind the rest of the code and the file meta data.
    Metadata details:
    filename: activation.rb
    path of file: ./repos/workarea/core/app/models/workarea/release
    
    the code of the file until where you have to start completion: module Workarea
  class Release
    module Activation
      extend ActiveSupport::Concern

      included do
        around_create :save_activate_with
        attr_accessor :activate_with
      end

      def save_activate_with
   
    
      def create_activation_changeset(release_id)
        set = changesets.find_or_initialize_by(release_id: release_id)
        set.document_path = document_path

        set.changeset = if Workarea.config.localized_active_fields
          { 'active' => { I18n.locale.to_s => true } }
        else
          { 'active' => true }
        end
        set.original = if Workarea.config.localized_active_fields
          { 'active' => { I18n.locale.to_s => false } }
        else
          { 'active' => false }
        end
