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: daily_dropoffs_report.rb
    path of file: ./repos/identity-idp/app/jobs/reports
    
    the code of the file until where you have to start completion: require 'csv'

module Reports
  class DailyDropoffsReport < BaseReport
    REPORT_NAME = 'daily-dropoffs-report'

    STEPS = %w[
      wel
    
    def report_body
      CSV.generate do |csv|
        csv << %w[
          issuer
          friendly_name
          iaa
          agency
          start
          finish
        ] + STEPS

        query_results.each do |sp_result|
          csv << [
            sp_result['issuer'],
            sp_result['friendly_name'],
            sp_result['iaa'],
            sp_result['agency'],
            start.iso8601,
            finish.iso8601,
            *STEPS.map { |step| sp_result[step].to_i },
          ]
        end
      end
    end
