更新Messenger处理程序(Symfony)中的一个实体。

问题描述 投票:0回答:1

我想把我的重度治疗转移到。信使.

我创建了一个DownloadTask实体,我试图在过程中更新它,但它不工作。我的实体没有在数据库中更新。

你有什么想法吗?

我还在学习,所以我希望我的代码不会太伤你们的眼睛。

<?php

应该

$task =  $this->downloadTaskRepository->find($getSellerList->getDownloadTaskId());

$this->task =  $this->downloadTaskRepository->find($getSellerList->getDownloadTaskId());

?
