Using "processDatamap_afterDatabaseOperations" with "tx_news_domain_model_news" and status "new" ends up without empty category

Question

I'm using the "processDatamap_afterDatabaseOperations" hook within my extension to transfer content from a newly created News (tx_news_domain_model_news) to an API.

TYPO3 Version is 6.2.11 and if I var_dump or trying to access the category using $record->getCategories() it's empty. Same with related files, falmedia works. Here is my code:

public function processDatamap_afterDatabaseOperations($status, $table, $id, array $fieldArray, \TYPO3\CMS\Core\DataHandling\DataHandler &$pObj) {
    if ($table == 'tx_news_domain_model_news' && $status == 'new') {
        $objectManager  = \TYPO3\CMS\Core\Utility\GeneralUtility::makeInstance('TYPO3\CMS\Extbase\Object\ObjectManager');
        $news           = $objectManager->get('GeorgRinger\News\Domain\Repository\NewsRepository');
        $record         = $news->findByUid($pObj->substNEWwithIDs[$id]);

Hope anybody knows what I'm doing wrong here. I've been trying this like forever and don't get it.

Thanks in advance for your help.

That's likely because "afterDatabaseOperations" is called for each record insertion/update in each table, and that the relation between the record and the categories has not been established yet.

Only after all insertions/updates have been done, the method processRemapStack is called by the DataHandler, that sets/fixes all the relations between the various records (e.g. wherever there was a "NEW.." relation in the datamap, the correct uids are set).

The only hook you can use, where alle records have the correct relations is the processDatamap_afterAllOperations hook, that you can find at the very end of the process_datamap in the DataHandler class.

That one only takes a single argument though (the DataHandler instance), so you probably have to try and get the inserted news records using the "datamap" property of the DataHandler reference.

Thanks for you reply. I had a bad feeling about this. :-) Can I get the ID and the status out of processDatamap_afterAllOperations? Or is this the wrong aproach? — lufi, Dec 15 '19 at 18:22
You get an instance of the DataHandler class as first argument to the method. That class has a "datamap" property, that contains the records that have been inserted/updated. Something like `$dh->datamap['tx_news_domain_model_news']` could give you an assoc array (uid => record) of inserted/updated news records (might be empty though), and if the uid starts with "NEW...", then it was an inserted record ... But I have no idea if that is the correct approach. — Nitori, Dec 16 '19 at 07:52
