Answer 1

You can do this with one query in your Category controller and a nested loop in the view:

in the Category controller:

function some_action () {
   $options = array (
      'recursive' => 1,
      'order' => array ( 'Category.name' => 'asc' )
   );
   $categories = $this->Category->find ( 'all', $options );
   $this->set ( 'categories', $categories );
}

and in the view:

<?php
foreach ( $categories as $c ) {
   echo $c['Category']['name'] . '<br />';
   foreach ( $c['Post'] as $p ) {
      echo ' &nbsp; ' . $p['name'] . '<br />';
   }
   echo '<br />';
}
?>
