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: notice_of_disagreements_controller.rb
    path of file: ./repos/vets-api/modules/appeals_api/app/controllers/appeals_api/notice_of_disagreements/v0
    
    the code of the file until where you have to start completion: # frozen_string_literal: true

require 'appeals_api/form_schemas'

module AppealsApi::NoticeOfDisagreements::V0
  class NoticeOfDisagreementsController < AppealsApi::ApplicationController
    include
    
    def download
      render_appeal_pdf_download(
        AppealsApi::NoticeOfDisagreement.find(params[:id]),
        "#{FORM_NUMBER}-notice-of-disagreement-#{params[:id]}.pdf",
        veteran_icn
      )
    rescue ActiveRecord::RecordNotFound
      render_notice_of_disagreement_not_found(params[:id])
    end
