我有一个场景，我试图在与我的主模型相关联的模型上使用group by使用groupable。
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.

我想通过SubFirmDetail分组，只显示最新的SubFirmDetail，具体取决于subFirmDetailType。这是我目前在我的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));
$this->redirect(array('action' => 'index'));
}
}
答案 0 :(得分：0)
我最终不得不在数据库中创建一个视图并输出一个我在条件子句中包含的数组......对于那些尝试相同的人。
答案 1 :(得分：-1)
试试这个：
function view($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),
'group' => 'Subfirmdetail',
'order' => 'date',
));
$this->set('subfirm', $data);
if (!$id) {
$this->Session->setFlash(__('Invalid subfirm', true));
$this->redirect(array('action' => 'index'));
}
}
