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: operatingsystems_controller.rb
    path of file: ./repos/foreman/app/controllers/api/v2
    
    the code of the file until where you have to start completion: module Api
  module V2
    class OperatingsystemsController < V2::BaseController
      include Foreman::Controller::Parameters::Operatingsystem
      include ParameterAttributes

      re
    
      def bootfiles
        Foreman::Deprecation.api_deprecation_warning("Bootfiles should be calculated per host")

        medium = Medium.authorized(:view_media).find(params[:medium])
        arch   = Architecture.authorized(:view_architectures).find(params[:architecture])
        host_mock = Openstruct.new(operatingsystem: @operatingsystem, medium: medium, architecture: arch)
        medium_provider = MediumProviders::Default.new(host_mock)

        render :json => @operatingsystem.pxe_files(medium_provider)
      rescue => e
        render_exception(e, :status => :unprocessable_entity)
      end
