title: Rails: Finding children of children in habtm activerecord relationships
body: <p>I have 3 classes related by habtm associations...Users, Locations, Employees. </p>
  
  <p>Users is related to Locations via a habtm relationship, and Locations is related to Employees via a habtm relationship.</p>
  
  <p>What I would like to be able to do is say:</p>
  
  <p>current_user.locations.employees</p>
  
  <p>Does anyone know the "Rails Way" to do this? I can do it in SQL, but I am wondering if there is a cleaner way.</p>
