Doctrine 忽略 property/column

Question

我正在将基于 Zend\Db 的应用程序迁移到 Doctrine 2。

问题出在实体 AuditLog 上。在迁移之前，它一直存在 Zend\Db（请参阅代码块 1）。

现在实体 AuditLog 有多个子类，它们一起实现了 Single Table Inheritance 模式（参见代码块 2）。

自从我切换到 Doctrine 后，我应该只需要创建一个适当的 AuditLog 对象并简单地 persist(...) 它。事实上，这是我正在尝试的（参见代码块 3）。但是现在我遇到了 AuditLog 的属性 $resourceId 的问题：Doctrine 似乎忽略了它。属性包含正确的值（我在调试器中看到它），但 INSERT 语句没有得到它，看起来像：

INSERT INTO audit_log
    (resource_id, action, datetime, user_id, resource_type)
VALUES
    (NULL, 'order.created', NULL, 1, 'order');

结果是：实体被持久化，但是 resource_id 是空的。

为什么 Doctrine 忽略这个属性以及如何保存它？

代码

1 坚持Zend\Db

AuditLogger

class AuditLogger extends AbstractPlugin
{
    ...
    public function log($resourceType = null, $resourceId = null, $action = null, $userId = null)
    {
        $auditLog = new AuditLog();
        $auditLog->setResourceType($resourceType);
        $auditLog->setResourceId($resourceId);
        $auditLog->setAction($action);
        ...
        $auditLog->setUser($this->user);
        $this->auditLogService->create($auditLog);
        // The AuditLogService calls then the AuditLogMapper#create(...).
    }
}

AuditLogMapper

class AuditLogMapper extends AbstractMapper implements AuditLogMapperInterface
{
    ...
    public function create(AuditLog $dataObject)
    {
        $data = [];
        // data retrieved directly from the input
        $data['resource_type'] = $dataObject->getResourceType();
        $data['resource_id'] = $dataObject->getResourceId();
        $data['action'] = $dataObject->getAction();
        $data['datetime'] = $dataObject->getDatetime();
        $data['user_id'] = $dataObject->getUser()->getId();

        $action = new Insert('audit_log');
        unset($data['id']);
        $action->values($data);

        $sql = new Sql($this->dbAdapter);
        $statement = $sql->prepareStatementForSqlObject($action);
        $result = $statement->execute();

        if ($result instanceof ResultInterface) {
            $newId = $result->getGeneratedValue() ?: $dataObject->getId();
            if ($newId) {
                $dataObject->setId($newId);
            }
            return $dataObject;
        }
        throw new \Exception('Database error in ' . __METHOD__);
    }
}

    public function create(AuditLog $dataObject)
    {
        $currentUser = $this->entityManager->getRepository(User::class)->find(

Answer 1

由于 resource_id 用作 JoinColumn

/**
 * @var Order
 *
 * @ORM\ManyToOne(targetEntity="Order")
 * @ORM\JoinColumn(name="resource_id", referencedColumnName="id")
 */
protected $order;

不是普通的属性了，可以直接设置。需要改为设置相关实体：

...

class AuditLogger extends AbstractPlugin
{

    ...

    /**
     * @var User
     */
    protected $user;

    public function __construct(
        AuditLogServiceInterface $auditLogService,
        OrderInterface $order,
        ServerServiceInterface $serverService,
        ClusterServiceInterface $clusterService,
        User $user = null
    ) {
        $this->auditLogService = $auditLogService;
        $this->order = $order;
        $this->serverService = $serverService;
        $this->clusterService = $clusterService;
        $this->user = $user;
    }

    public function log($resourceType = null, $resourceId = null, $action = null, $userId = null)
    {
        switch ($resourceType) {
            case AuditLog::RESSOURCE_TYPE_ORDER:
                $auditLog = new AuditLogFileTransferRequest();
                $resource = $this->order->findOne($resourceId);
                $auditLog->setFileTransferRequest($resource);
                break;
            case AuditLog::RESSOURCE_TYPE_SERVER:
                $auditLog = new AuditLogServer();
                $resource = $this->serverService->findOne($resourceId);
                $auditLog->setServer($resource);
                break;
            case AuditLog::RESSOURCE_TYPE_CLUSTER:
                $auditLog = new AuditLogCluster();
                $resource = $this->clusterService->findOne($resourceId);
                $auditLog->setCluster($resource);
                break;
            default:
                $auditLog = new AuditLog();
        }
        $auditLog->setAction($action);
        if ($userId) {
            $user = new User();
            $user->setId($userId);
            $auditLog->setUser($user);
        } elseif ($this->user) {
            $auditLog->setUser($this->user);
        }
        $this->auditLogService->create($auditLog);
    }

}
