TYPO3 v9 Scheduler does not persist the data - typo3

Question

I have a function that loads data from a JSON file and enters it into the TYPO3 database. If I call this function via the backend Controller (indexAction), then everything works fine. However, when I call it from a task, the data is not saved. By means of test output I see that the object was changed correctly, only the Update or Add is not executed correctly, because the data in the database is not changed.
Here is my controller function:
class ImportController extends \TYPO3\CMS\Extbase\Mvc\Controller\ActionController
{
protected $siteRepository = null;
public function injectSiteRepository(SiteRepository $siteRepository)
{
$this->siteRepository = $siteRepository;
}
public function indexAction()
{
$this->dataImport();
}
public function dataImport() {
$file = "test.json";
$json = file_get_contents($file);
$jsonarray = json_decode($json);
foreach ($jsonarray->{'sites'} as $site) {
$newValue = false;
$dbSite = $this->siteRepository->getSiteByID($site->{'ID'});
if (empty($dbSite->getFirst())) {
$dbSite = \TYPO3\CMS\Core\Utility\GeneralUtility::makeInstance('test\test123\Domain\Model\Site');
$dbSite->setID($site->{'ID'});
$newValue = true;
} else {
$dbSite = $dbSite->getFirst();
}
//Set Data
$dbSite->setTest($site->{'TEST'});
//This object is correct, even in the Task
DebuggerUtility::var_dump(
$dbSite
);
//Update or Add new Data
if (!$newValue) {
$this->siteRepository->update($dbSite);
} else {
$this->siteRepository->add($dbSite);
}
}
$persistenceManager = \TYPO3\CMS\Core\Utility\GeneralUtility::makeInstance('TYPO3\CMS\Extbase\Persistence\Generic\PersistenceManager');
$persistenceManager->persistAll();
return true;
}
}
Here is my task:
class JsonImportTask extends AbstractTask {
public function execute() {
$objectManager = GeneralUtility::makeInstance(
ObjectManager::class
);
$controller = $objectManager->get(ImportController::class);
$controller->dataImport();
return true;
}
}
Here my repository:
public function getSiteByID($id) {
$query = $this->createQuery();
$query->matching(
$query->equals("uid", $id),
);
return $query->execute();
}
Does anyone have an idea what this could be?

Answer 1

Ok I found my mistake myself. Here is the solution for all who have the same problem:
I added setRespectStoragePage in my getSiteByID function in SiteRepository:
$query->getQuerySettings()->setRespectStoragePage(false);
The error was that it was looking for the data at StoragePid 1. With this command he searches at the right place
Here is my correct repository function:
public function getSiteByID($id) {
$query = $this->createQuery();
$query->getQuerySettings()->setRespectStoragePage(false);
$query->matching(
$query->equals("uid", $id),
);
return $query->execute();
}
I had another problem. You have to set the PID number for new entries.
For example, my data is stored on Page ID 12.
I added this line here:
if (empty($dbSite->getFirst())) {
$dbSite = \TYPO3\CMS\Core\Utility\GeneralUtility::makeInstance('test\test123\Domain\Model\Site');
$dbSite->setID($site->{'ID'});
$newValue = true;
$dbSite->setPid(12); //New Line set PID (For me to PID 12)
} else {
$dbSite = $dbSite->getFirst();
}
