x entri blog terakhir - tetapi hanya sekali per pengguna

Menggunakan subquery tampaknya berhasil - dengan sedikit trik ini:

$options = array(
    'fields' => array('MAX(SubBlog.created)'),
    'conditions' => array('SubBlog.user_id = Blog.user_id')
);
$subquery = $this->subquery('all', $options);

$options = array(
    'order'=>array($this->alias.'.published' => 'DESC'),
    'conditions' => array(
        'User.active' => 1,
        'Blog.status' => self::STATUS_ACTIVE, 
        'Blog.published = ' . $subquery
    ),
    'contain' => array('User.username'),
    'fields' => array(
        'User.id',  'User.username', 
        'Blog.id', 'Blog.headline', 'Blog.published'
    ),
    'limit' => $limit,
);
return $this->find('all', $options);

subquery() adalah metode AppModel:https://github .com/dereuromark/tools/blob/2.0/Lib/MyModel.php#L405
