根据 Elias 和 Jonas 的回答,我创建了一个可以简化事情的类,尤其是当您有更多模型要处理时
typo3conf/ext/sitepackage/Classes/Utility/SlugUtility.php

在任何地方使用,如控制器。调度任务、存储库等。请记住,记录应该在之前保存(它可能是由 Extbase 创建的,或者只是使用普通 SQL),只需要已经创建uid
并且是有效的 TYPO3 记录。
use VENDOR\Sitepackage\Utility\SlugUtility;
use \TYPO3\CMS\Extbase\Persistence\Generic\PersistenceManager;
...
$pageSlug = SlugUtility::generateUniqueSlug(
5, // int $uid UID of record saved in DB
'pages', // string $tableName Name of the table to lookup for uniques
'slug' // string $slugFieldName Name of the slug field
)
// or
$uniqueSlug = SlugUtility::generateUniqueSlug(
123,
'tx_garage_domain_model_car',
'slug'
);
// or according to the original question,
// if you created new model object with Extbase,
// persist it, create unique slug with SlugUtility
// set the slug property to the created model object and finally update
public function createAction(Car $newCar)
{
$this->carRepository->add($newCar);
GeneralUtility::makeInstance(PersistenceManager::class)->persistAll();
$uniqueSlug = SlugUtility::generateUniqueSlug(
$newCar->getUid(),
'tx_garage_domain_model_car',
'slug'
);
if($uniqueSlug) {
$newCar->setSlug($uniqueSlug);
$this->carRepository->update($newCar);
}
$this->redirect('list');
}
// no need for second call to persistAll()
// as Extbase will call it at action's finalizing.
// etc.
