            } catch (Exception $exception) {
                $transaction->rollBack();
                throw new Exception($exception->getMessage());
            }
        } else {

    }

I met a problem to ask , in the database transaction, insert a piece of data, and then the direct model query can be queried out, but through the associated query can not query processing, how to solve this? Such problems can cause data inconsistencies？ can you help me .

//can read new row data
$a = self::findAll(['order_id' => $this->order_id]);

//but,can't read new row data
$b = $this->order->orderPaymentLogs;
