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: response.rb
    path of file: ./repos/vets-api/modules/meb_api/lib/dgi
    
    the code of the file until where you have to start completion: # frozen_string_literal: true

require 'common/client/concerns/service_status'
require 'common/models/base'
module MebApi
  module DGI
    ##
    # Model 
    
      def response_status
        case status
        when 200
          RESPONSE_STATUS[:ok]
        when 403
          RESPONSE_STATUS[:not_authorized]
        when 404
          RESPONSE_STATUS[:not_found]
        else
          RESPONSE_STATUS[:server_error]
        end
