php - cakephp 删除在模型中不起作用

Question

class Model extends AppModel{

  public function deleteSomething(){

    if (empty($this->id)) {
      return false;
    }

    $this->read();

    $db =& ConnectionManager::getDataSource($this->useDbConfig);

    $db->begin($this);

    if (! $this->delete($this->id, true)) {
      $db->rollback($this);
      return false;
   }
   return $db->commit($this);
}

由于某种原因，这不会删除？？我已经调试了id，它是正确的。有任何想法吗？我错过了什么吗？}

Answer 1

我看不到任何提交功能。我认为应该是：

if (! $this->delete($this->id, true)) {
    $db->rollback($this);
    return false;
}
$db->commit($this);  
return true;

Answer 2

public function delete()
    {
        $this->layout = 'iphone_gps';
        $this->set('title_for_layout','Iphone GPS, LLC : Companies');
        $this->Companies = $this->request->data;
        if ($this->request->is('get')) {
            throw new MethodNotAllowedException();
        }
        foreach($this->Companies as $ids){
            $this->Companie->deleteAll(array('Companie.company_id' => $ids));
        }
        $this->Session->setFlash($this->deleted);
        $this->redirect('index');
    }

在控制器中创建一个删除功能......然后在 index.ctp 页面中创建下一个

echo "<br>".$this->Form->input('Delete',array('class' => 'youreclass','style' => 'display:block;width:100px;','onclick'=>"return confirm('Are you sure for delete data?')",array('type'=>'hidden')));
