交易并不在Yii中工作 [英] Transaction doesn't work in Yii

问题描述

这是我的code：

$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();
            }

$的tModel 保存，但 $ activati​​onLink 不那么它应该回滚。但事与愿违，为什么？

$tModel saved but $activationLink doesn't so it should rolled back. but it didn't ,why?

推荐答案

Yii的保存（）时，就在验证失败时不抛出异常。因此，你必须检查保存（的结果）自己：

Yii save() does not throw an exception, when just the validation fails. Thus you have to check the result of save() yourself:

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

//or:

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