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: brand.rb
    path of file: ./repos/beer.db/beerdb-models/lib/beerdb/models
    
    the code of the file until where you have to start completion: # encoding: UTF-8

module BeerDb
  module Model

class Brand < ActiveRecord::Base

  # NB: use extend - is_<type>? become class methods e.g. self.is_<type>?
  extend TextUtils::ValueHelper  # e.g. self.find_key_n_title, self.is_year?, self.is_state?, is_address?, is_taglist? etc.

  belongs_to :country, :class_name => 'WorldD
    
  def self.create_or_update_from_attribs( attribs, values )

    ## fix: add/configure logger for ActiveRecord!!!
    logger = LogKernel::Logger.root

    ## check for grades (e.g. ***/**/*) in titles (will add attribs[:grade] to hash)
    ## if grade missing; set default to 4; lets us update overwrite 1,2,3 values on update
    attribs[:grade] ||= 4

    rec = Brand.find_by_key( attribs[:key] )

    if rec.present?
      logger.debug "update Brand #{rec.id}-#{rec.key}:"
    else
      logger.debug "create Brand:"
      rec = Brand.new
    end
