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: promote_job.rb
    path of file: ./repos/shrine/demo/jobs/attachment
    
    the code of the file until where you have to start completion: require "sucker_punch"

module Attachment
  class PromoteJob
    include SuckerPunch::Job

    def perform(attacher_class, record_
    
    def perform(attacher_class, record_class, record_id, name, file_data)
      attacher_class = Object.const_get(attacher_class)
      record         = Object.const_get(record_class).with_pk!(record_id)

      attacher = attacher_class.retrieve(model: record, name: name, file: file_data)
      attacher.create_derivatives if record.is_a?(Album)
      attacher.atomic_promote
    rescue Shrine::AttachmentChanged
      # attachment has changed, so nothing to do
    rescue Sequel::NoMatchingRow, Sequel::NoExistingObject
      # record has been deleted, so nothing to do
    end
  end
