Doctrine 不是冲洗实体并且返回错误的值，发生了什么？

Question

我将这段代码作为 Restful API 方法的一部分：

// $soqlObj1['records'][0]['Id'] == "005800000039cQbAAI"

$entRep = $em->getRepository('PDOneBundle:Representative')->find($soqlObj1['records'][0]['Id']);

dump($entRep); // line 114

if ($entRep->getRepTokenId() === null) {
    $xsession = bin2hex(openssl_random_pseudo_bytes(100));
    $entRep->setRepTokenId($xsession);
    $em->flush();

    dump($xsession); // line 121
    dump($entRep->getRepTokenId()); // line 122
}

dump($entRep); // line 125

这是每个 dump() 语句的输出：

in SessionRestController.php line 114:

如果我在 DB 运行这个查询 SELECT repTokenId, updatedAt FROM reps WHERE rep_id='005800000039cQbAAI' 我得到这个结果：

为什么实体返回了错误的值？为什么正确的 $xsession 值没有更新？为什么 $entRep->getRepTokenId() 会给我一个 unknow 值，而这个值在会话变量或任何其他地方都不存在？这里发生了什么？

Answer 1

这很奇怪。开始时，来自数据库的 repTokenId 为空（在行 114 中转储）。在持久化您的实体（转储 125 行）和数据库（您的 SELECT sql）之后，其值不同于 null。结论：Doctrine 是刷新实体，因为如果不是的话，你将在 db.null 中拥有

你在 db 中的新值是你的令牌，但它以某种方式被截断了。所以我会检查两件事：

数据库中 repTokenId 字段的长度。这么长的值够长吗？
实体定义中 repTokenId 字段的长度

Doctrine 不是冲洗实体并且返回错误的值，发生了什么？

Doctrine is not flushing entity and is returning the wrong value, what's happen?
