title: How do i specify and validate an enum in rails?
body: <p>I currently have  a model Attend that will have a status column, and this status column will only have a few values for it.  STATUS_OPTIONS = {:yes, :no, :maybe}</p>
  
  <p>1) I am not sure how i can validate this before a user inserts an Attend?  Basically an enum in java but how could i do this in rails?</p>
