When we define an error class in a module, we do one of the following.

module App
  class Error < StandardError; end
  class ServerError < Error; end
  class ClientError < Error; end
end

kenn

class << self
  def recent
    where(...)
  end
end

module Scopes
  def recent
    where(...)
  end

kenn

class Person < ActiveRecord::Base
  def self.recent
    where('added_at > ? AND deleted = ?', ...).where('address IS NULL').order('last_name, first_name')
  end
end
