我有一个场景，我试图在与我的主模型关联的模型上使用 group by，使用可包含。
这是我的输出：

[description] => There are many variations of passages of Lorem Ipsum available, but the majority have suffered alteration in some form, by injected humour, or randomised words which don't look even slightly believable. If you are going to use a passage of Lorem Ipsum, you need to be sure there isn't anything embarrassing hidden in the middle of text. All the Lorem Ipsum generators on the Internet tend to repeat predefined chunks as necessary, making this the first true generator on the Internet. It uses a dictionary of over 200 Latin words, combined with a handful of model sentence structures, to generate Lorem Ipsum which looks reasonable. The generated Lorem Ipsum is therefore always free from repetition, injected humour, or non-characteristic words etc.

我想按 SubFirmDetail 分组，并且仅根据 subFirmDetailType 显示最新的 SubFirmDetail。这是我目前在控制器中使用的代码：
function view($id = null) {
$this->Subfirm->recursive = -1;
$data = $this->Subfirm->find('first', array(
'contain' => array(
'Subfirmdetail' => array(
'Subfirmdetailtype' => array(
'Datatype',
),
),
'Firm' => array(
'Firmtype',
),
),
'conditions' => array('Subfirm.id' => $id),
));
$this->set('subfirm', $data);
if (!$id) {
$this->Session->setFlash(__('Invalid subfirm', true));
$this->redirect(array('action' => 'index'));
}
}
