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: deployment.rb
    path of file: ./repos/gitlabhq/app/models
    
    the code of the file until where you have to start completion: # frozen_string_literal: true

class Deployment < ApplicationRecord
  include AtomicInternalId
  include IidRoutes
  include AfterCommitQueue
  include Upda
    
  def older_than_last_successful_deployment?
    last_deployment_id = environment&.last_deployment&.id

    return false unless last_deployment_id.present?
    return false if id == last_deployment_id
    return false if sha == environment.last_deployment&.sha

    id < last_deployment_id
  end
