Symfony，无法从表中检索记录

Question

在 Symfony 中，我无法使用 find() 从表中检索记录，但可以使用 createQuery()？这在我的项目中随机发生在我的桌子上。使用 symfony find()、findBy() 等似乎无法访问数据，但我可以使用 dql???

为什么会这样？有没有人发生过这种情况？我无法弄清楚这一点。感谢您的帮助！

我跑过的测试：我使用完全相同的实体字段创建了一个类似的表，并将数据导入到表中，它工作得非常好。为什么这个表刚刚停止响应 Symfony 的请求？

这可行

    $dql = "SELECT co FROM WIC\CommonBundle\Entity\CustomOptions co WHERE co.account=:account_id AND co.option_field=:value";
    $query = $em->createQuery($dql);
    $query->setParameters(array(
        'value' => 'reorder_reason',
    ));
    $customOptionValue = $query->getResult();
    echo count($customOptionValue); // equals 3

这不起作用 - 传入完全相同的变量

    $customOptionValue = $em->getRepository('WICCommonBundle:CustomOptions')->findBy(
    array(
           "option_field"=>"reorder_reason",
        )
    );
    echo count($customOptionValue); // equals 0

这是我的 CustomOptions 实体：

Answer 1

尝试使用 ID 而不是整个对象

即

$customOptionValue = $em->getRepository('WICCommonBundle:CustomOptions')->findBy(array(
    "account"=>$account->getId(), 
    "option_field"=>"reorder_reason",
));

编辑：是你没有遵循 symfony 所期望的编码标准导致了这个问题：

Use camelCase, not underscores, for variable, function and method names

private $option_field 应该变成 private $optionField 并且您应该调整您创建的任何函数以反映这一点。然后你的 findBy 数组将使用"optionField"=>"reorder_reason"

Answer 2

我看到您使用的是软@Gedmo\SoftDeleteable。请检查存在且无法检索的记录是否没有设置deletedAt？

Doctrine 查询忽略设置了 deletedAt 的记录。但是假设“非教条查询”仍然能够找到这些记录。
