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: preferable_class_methods.rb
    path of file: ./repos/openfoodnetwork/app/models/spree/preferences
    
    the code of the file until where you have to start completion: # frozen_string_literal: true

module Sp
    
      def preference(name, type, *args)
        options = args.extract_options!
        options.assert_valid_keys(:default, :description)
        default = options[:default]
        description = options[:description] || name

        # cache_key will be nil for new objects, then if we check if there
        # is a pending preference before going to default
        define_method preference_getter_method(name) do
          # perference_cache_key will only be nil/false for new records
          #
          if preference_cache_key(name)
            preference_store.get(preference_cache_key(name), default)
          else
            get_pending_preference(name) || default
          end
        end
