title: ActiveRecord::Base Without Table
body: <p>This came up a bit ago ( <a href="https://stackoverflow.com/questions/399490">rails model attributes without corresponding column in db</a> ) but it looks like the Rails plugin mentioned is not maintained ( <a href="http://agilewebdevelopment.com/plugins/activerecord_base_without_table" rel="nofollow noreferrer">http://agilewebdevelopment.com/plugins/activerecord_base_without_table</a> ). Is there no way to do this with ActiveRecord as is? </p>
  
  <p>If not, is there any way to get ActiveRecord validation rules without using ActiveRecord?</p>
  
  <p>ActiveRecord wants the table to exist, of course.</p>
