yii2 活动记录事务在验证失败时仍然提交

Question

我正在使用 Yii2 活动记录事务，但是在代码中间验证失败，它仍然提交事务。请指教。

public function actionCreate()
{
    $model = new PoAgen();
    $seq = Sequence::FindOne(['seq_id' => 'INV/AG', 'seq_name' => (int)date('ymd')]);
    if(is_null($seq))
    {
        $_seq = new Sequence();
        $_seq->seq_id = 'INV/AG';
        $_seq->seq_name = (int)date('ymd');
        $_seq->value = 0;
        $_seq->save();
        $model->trx_id = $_seq->seq_id . '/' . $_seq->seq_name . str_pad($_seq->value+1, 3, "0", STR_PAD_LEFT);
    }
    else {
        $seq->value += 1;
        $model->trx_id = $seq->seq_id . '/' . $seq->seq_name . str_pad($seq->value, 3, "0", STR_PAD_LEFT);
        $seq->update();
    }

    $model->pot_cong = 0;
    $model->pot_basah_kg = 0;
    $model->pot_tangkai = 0;
    $model->ppn = 0;
    $model->pot_pinjaman = 0;
    $model->pot_panjar = 0;
    $model->ongkos_angkut = 0;
    $model->pot_angkut = 0;
    $model->is_transfer = true;
    $model->buy_date = date('Y-m-d');

    if ($model->load(Yii::$app->request->post())) {
        $transaction = Yii::$app->db->beginTransaction();
        try
        {
            $model->created_by = Yii::$app->user->identity->id;
            $model->created_time = date('Y-m-d H:i:s');

            $saldo = Saldo::findOne(1); 
            $kas = Kas::findOne(1000); // pembelian agen pks
            $agen = Agen::findOne($model->agen_id);

            if(!$model->is_transfer)
            {
                if($kas->code == 'D')
                {
                    $saldo->balance -= $model->total_bayar;
                }
                else 
                {
                    $saldo->balance += $model->total_bayar;
                }
                $saldo->update();
            }
            $model->save();

            // posting to kasbook
            $kasbook = new KasBook();
            $kasbook->kasbook_id = uniqid();
            $kasbook->kas_date = $model->buy_date;
            $kasbook->ref_trxid = $model->trx_id;
            $kasbook->kas_id = $kas->kas_id;
            $kasbook->code = $kas->code;
            $kasbook->total = $model->total_bayar;
            $kasbook->balance = $saldo->balance;
            $kasbook->received_by = '['. $model->agen_id . '] ' . $agen->agen_name;
            $kasbook->remark = 'Berat Bersih : ' . $model->r_bersih . ', Harga : ' . $model->price;
            $kasbook->vehicle_id = $model->vehicle_id; 
            $kasbook->is_transfer = $model->is_transfer;
            $kasbook->created_by = Yii::$app->user->identity->id;
            $kasbook->created_time = date('Y-m-d H:i:s');
            $kasbook->save();

            if($model->ppn != 0)
            {
                $kb_1 = new KasBook();
                $kb_1->kasbook_id = uniqid();
                $kb_1->kas_date = $model->buy_date;
                $kb_1->ref_trxid = $model->trx_id;
                $kb_1->kas_id = 2000;
                $kb_1->code = 'K';
                $kb_1->total = $model->ppn;
                $kb_1->balance = $saldo->balance;
                $kb_1->remark = 'Ppn Pembelian Agen';
                $kb_1->vehicle_id = $model->vehicle_id;
                $kb_1->is_transfer = true;
                $kb_1->created_by = Yii::$app->user->identity->id;
                $kb_1->created_time = date('Y-m-d H:i:s');
                $kb_1->save();
            }

            // kurang posting ke purchase order barang
            $transaction->commit();
            return $this->redirect(['view', 'id' => $model->trx_id]);
        }
        catch(Exception $e) {                
            $transaction->rollBack();
            throw $e;
        }            
    } else {
        return $this->render('create', [
            'model' => $model,
        ]);
    }
}

验证失败，if($model->ppn !=0) { ... } 因为主表中没有任何主键，但事务仍然提交并将模型插入到数据库中。请指教。之前谢谢。

Answer 1

save()方法不会抛出异常，而是返回布尔值，所以你需要明确地抛出它。更换每

...->save();

尝试捕捉

if (! ...->save()) {
    throw new \yii\db\Exception('Error while saving ... model!');
    // or use general \Exception()
}

所以现在它可以被抓住了。
