学说2 ZF3自我引用实体并未更新父的所有字段

Question

我与父母和孩子有一个自我引用实体。奇怪的是，当我将父元素(doctrinemodule objectselect(添加到for for for for表单时，当我坚持该实体时，父母实体的其他一些字段不会更新。儿童实体更新。

在父母的更新查询中，不是我要更新的这些字段。就像学说不再识别父母(拥有方(的更改。在持久之前，我获得了正确的实体，具有从表单中的实际更改，但除了学说没有更新查询中的更改字段。

当我以表单中的父和子女的形式元素删除表单元素时，一切正常，父母实体更新/坚持所有字段。

基于答案(可能仍会更改(根据与OP的评论中的讨论。

简单的用例：自我引用学说实体无法正确更新与储蓄行动的父/儿童相关实体对象属性。

---

OP提供的实体。

我假设您为该实体设置了表单。我还假设它是正确的设置，因为您在被询问后没有提供(因为正确的是，这意味着很多代码(。但是，假设有代码的东西会造成很多错误，这就是为什么我在这里提到它的原因。

因此，我假设在控制器中处理您的表格可能是错误的。要检查，请使用以下简化的addAction功能并给它拍摄(下面的出厂代码(。

/**
 * @var RentalForm
 */
protected $form;
/**
 * @var ObjectManager
 */
protected $objectManager;
public function __construct(ObjectManager $objectManager, RentalForm $form)
{
    $this->form = $form;
    $this->objectManager = $objectManager;
}
public function addAction()
{
    /** @var RentalForm $form */
    $form = $this->getForm();
    /** @var Request $request */
    $request = $this->getRequest();
    if ($request->isPost()) {
        $form->setData($request->getPost());
        if ($form->isValid()) {
            $entity = $form->getObject();
            $this->getObjectManager()->persist($entity);
            try {
                $this->getObjectManager()->flush();
            } catch (Exception $e) {
                $message = sprintf(
                    'Was unable to save the data. Saving threw an error. <br />Code: %s. <br />Message: %s',
                    $e->getCode(),
                    $e->getMessage()
                );
                $this->flashMessenger()->addErrorMessage($message);
                return [
                    'form' => $form,
                    'validationMessages' => $form->getMessages() ?: '',
                ];
            }
            $this->flashMessenger()->addSuccessMessage(
                $this->getTranslator()->translate('Successfully created object.')
            );
            // TODO replace vars with your own: return $this->redirect()->route($route, $routeParams);
        }
        $this->flashMessenger()->addWarningMessage(
            'Your form contains errors. Please correct them and try again.'
        );
    }
    return [
        'form' => $form,
        'validationMessages' => $form->getMessages() ?: '',
    ];
}

上课的工厂，根据需要修改情况

class RentalControllerFactory implements FactoryInterface
{
    public function __invoke(ContainerInterface $container, $requestedName, array $options = null)
    {
        /** @var ObjectManager $objectManager */
        $objectManager = $container->get(EntityManager::class);
        /** @var FormElementManagerV3Polyfill $formElementManager */
        $formElementManager = $container->get('FormElementManager');
        /** @var RentalForm $form */
        $form = $formElementManager->get(RentalForm::class);
        return new RentalController($objectManager, $form);
    }
}
