title: Cakephp Select foreign key and order by name!
body: <p>I can get drop downs from foreign keys but how to sort them by name instead of id.</p>
  
  <p>Adding 'order' => 'Country.name asc' in belongsTo model doesn't work, or I'm missing something!!!</p>
  
  <p>e.g. Choose country,  state, city, and those to be sorted by name, instead of id.</p>
