mysql - 交易在 Yii 中不起作用

Question

这是我的代码:

$transaction = Yii::app()->db->beginTransaction();
            try {
                $tModel->save();
                $activationLink = new ActivationLink;
                $activationLink->User_id = $tModel->id;
                $activationLink->hash1   = User::generateHashCode(100);
                $activationLink->hash2   = User::generateHashCode();
                $activationLink->hash3   = User::generateHashCode();
                $activationLink->time    = time();
                $activationLink->save();                    
                User::sendActivatonLink($tModel->mail,$activationLink->id, $activationLink->hash1, $activationLink->hash2, $activationLink->hash3);
                $transaction->commit();
                $this->redirect(array('view', 'id' => $tModel->id));
            } catch (Exception $e) {
                $transaction->rollback();
                Yii::app()->user->setFlash('error', "{$e->getMessage()}");
                $this->refresh();
            }

$tModel 已保存，但 $activationLink 未保存，因此它应该回滚。但它没有，为什么？

当验证失败时，Yii save() 不会抛出异常。因此你必须自己检查 save() 的结果:

if (!$model->save())
   $transaction->rollback();

//or:

if (!$model->save())
   throw new Exception("This will trigger my catch statement block");
