title: How can I add a property to child association before render?
body: <p>I have a teacher model which has_many students. When I render a student (as json) I want to strip out the teacher_id property and replace it with the name of the teacher in my representation.</p>
  
  <p>What is the best way to achieve this?</p>
  
  <p>Cheers,</p>
