TYPO3 Extbase:如何在没有原始 sql 查询的情况下禁用相关对象? [英] TYPO3 Extbase: How to get disabled related Object, without raw sql-query?

问题描述

我有以下型号:

ContactPerson 与 FrontendUser 有关系，并且是关系的拥有方.现在我有以下问题:
我正在根据处于活动状态的 ContactPersons 在任务中激活/停用 FrontendUsers.当 FrontendUser 被禁用或删除时，contactPerson->getFrontendUser() 的结果为 null，即使两个存储库都忽略了EnableFields:

ContactPerson has a relation to FrontendUser and is the owning side of the relation. Now I have following problem:
I am activating/deactivating the FrontendUsers in a task, based on the ContactPersons which are active. When the FrontendUser is disabled or deleted the result of contactPerson->getFrontendUser() is null, even if both repositories ignoreEnableFields:

    /** @var Typo3QuerySettings $querySettings */
    $querySettings = $this->objectManager->get(Typo3QuerySettings::class);
    $querySettings->setIgnoreEnableFields(true);
    $querySettings->setRespectStoragePage(false);
    $this->frontendUserRepository->setDefaultQuerySettings($querySettings);

    $debugContactPerson = $this->contactPersonRepository->findOneByContactPersonIdAndIncludeDeletedAndHidden('634');
    $debugFrontendUser = $this->frontendUserRepository->findOneByUid(7);
    \TYPO3\CMS\Extbase\Utility\DebuggerUtility::var_dump(
        array(
            '$debugContactPerson' => $debugContactPerson,
            '$debugFrontendUser' => $debugFrontendUser,
        )
    );

结果:

Ps:$this->frontendUserRepository->findByUid(7); 也不起作用，因为它没有使用查询，但是 persistenceManager->getObjectByIdentifier(... 这当然会忽略查询设置.

P.s.: $this->frontendUserRepository->findByUid(7); also doesn't work because it isn't using the query, but persistenceManager->getObjectByIdentifier(... which is of course ignoring the query-settings.

问题是，在我的实际代码中，我无法使用 findOneByUid()，因为我无法在 contact_person 的 frontend_user 字段中获取 integer-Value(uid).

The problem is, in my real code I can't use findOneByUid(), because I can't get the integer-Value(uid) in the frontend_user field of the contact_person.

有什么方法可以在不使用原始查询来获取 contact_person-row 的情况下解决这个问题?

Any way to solve this without using a raw query to get the contact_person-row?

因为我不想编写自己的 QueryFactory 并且我不想向我的 contactPerson 添加冗余字段，所以我现在用原始语句解决了它.也许它可以帮助有同样问题的人:

Because I didn't want to write an own QueryFactory and I didn't want to add a redundant field to my contactPerson I solved it now with a raw statement. Maybe it can help someone with the same problem:

class FrontendUserRepository extends \TYPO3\CMS\Extbase\Domain\Repository\FrontendUserRepository
{
    /**
     * @param \Vendor\ExtKey\Domain\Model\ContactPerson $contactPerson
     * @return Object
     */
    public function findByContactPersonByRawQuery(ContactPerson $contactPerson){
        $query = $this->createQuery();

        $query->statement(
            "SELECT fe_users.* FROM fe_users" .
            " LEFT JOIN tx_extkey_domain_model_contactperson contact_person ON contact_person.frontend_user = fe_users.uid" .
            " WHERE contact_person.uid = " . $contactPerson->getUid()
        );
        return $query->execute()->getFirst();
    }

}

推荐答案

直接调用仓库

fe_users表的enable字段有两个方面:

Invoking repository directly

There are two aspects for the enable fields of table fe_users:

• $querySettings->setIgnoreEnableFields(true);
• $querySettings->setEnableFieldsToBeIgnored(['disable']);

看看一些wiki 页面 - 它说 6.2，但它在 7.6 和 8 的大多数部分仍然有效.但是，这仅适用于直接调用存储库的情况，而不适用于作为另一个实体的一部分检索实体的情况 - 在这种情况下，存储库不用于嵌套实体.

Have a look to some overview in the wiki page - it says 6.2, but it's still valid in most parts for 7.6 and 8 as well. However, this only works if the repository is invoked directly, but not if an entity is retrieved as part of another entity - in this case the repository is not used for nested entities.

隐式检索嵌套实体 - 这发生在 DataMapper::getPreparedQuery(DomainObjectInterface $parentObject, $propertyName) 中.要调整子实体的查询设置，必须重载 QueryFactoryInterface 实现.

Nested entities are retrieved implicitly - this happens in DataMapper::getPreparedQuery(DomainObjectInterface $parentObject, $propertyName). To adjust query settings for child entities, the QueryFactoryInterface implementation has to be overloaded.

在 ext_localconf.php 中注册一个替代实现(用你的扩展的真实类名替换 \Vendor\ExtensionName\Persistence\Generic\QueryFactory):

Register an alternative implementation in ext_localconf.php (replace \Vendor\ExtensionName\Persistence\Generic\QueryFactory with the real class name of your extension):

$extbaseObjectContainer = \TYPO3\CMS\Core\Utility\GeneralUtility::makeInstance(
    \TYPO3\CMS\Extbase\Object\Container\Container::class
);
$extbaseObjectContainer->registerImplementation(
    \TYPO3\CMS\Extbase\Persistence\Generic\QueryFactoryInterface::class,
    \Vendor\ExtensionName\Persistence\Generic\QueryFactory::class
);

---

在新的 Typo3 版本 (v8+) 中，registerImplementation 方法不再适用于 QueryFactory.相反，XCLASS 必须用于覆盖/扩展类:

---

With new Typo3 versions (v8+), the registerImplementation method no longer works for QueryFactory. Instead, a XCLASS must be used to overwrite/extend the class:

$GLOBALS['TYPO3_CONF_VARS']['SYS']['Objects'][\TYPO3\CMS\Extbase\Persistence\Generic\QueryFactory::class] = [
    'className' => \Vendor\ExtensionName\Persistence\Generic\QueryFactory::class,
];

---

然后在实现里面:

---

Then inside the implementation:

<?php
namespace \Vendor\ExtensionName\Persistence\Generic;
use TYPO3\CMS\Extbase\Domain\Model\FrontendUser;

class QueryFactory extends \TYPO3\CMS\Extbase\Persistence\Generic\QueryFactory {
    public function create($className) {
        $query = parent::create($className);
        if (is_a($className, FrontendUser::class, true)) {
            // @todo Find a way to configure that more generic
            $querySettings = $query->getQuerySettings();
            $querySettings->setIgnoreEnableFields(true);
            // ... whatever you need to adjust in addition ...
        }
        return $query;
    }
}
