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: release.rb
    path of file: ./repos/open-build-service/src/api/app/models/token
    
    the code of the file until where you have to start completion: class Token::Release < Token
  include MaintenanceHelper

  def call(options)
    set_triggered_at
    return unless options[:package]

    # uniq timestring for all targets
    time_now = Time.now.utc

    package_to_release = options[:package]
    if options[:targetproject].present? && options[:targetrepository].present? && options[:filter_source_repository].present?
      source_repository = Repository.find_by_project_and_name(options[:project].name, options[:filter_source_repository])
      target_repository = Repository.find_by_project_and_name(options[:targetproject], options[:targetrepository])
      ra
    
  def release(package_to_release, source_repository, target_repository, time_now, options)
    opts = { filter_source_repository: source_repository,
             manual: true,
             comment: 'Releasing via trigger event' }
    opts[:multibuild_container] = options[:multibuild_flavor] if options[:multibuild_flavor].present?
    opts[:filter_architecture] = options[:arch] if options[:arch].present?

    if package_to_release.present?
      release_package(package_to_release,
                      target_repository,
                      package_to_release.release_target_name(target_repository, time_now),
                      opts)
    else
