title: Multi Table Inheritance with rails 3
body: <p>Are there standards or best practices yet when it comes to multi table inheritance in rails 3? So far the best article I could find was:</p>
  
  <p><a href="http://mediumexposure.com/multiple-table-inheritance-active-record/" rel="noreferrer">http://mediumexposure.com/multiple-table-inheritance-active-record/</a></p>
  
  <p>But even that needed some changes(e.g. moving the requires to an initializer instead of the old /config/environment.rb)</p>
  
  <p>Any better resources / standards?</p>
