TYPO3 Extbase how to empty ObjectStorage

Question

I want to \"empty\" an ObjectStorage when updating a Object:

It\'s TYPO3 4.6 with a Extbase Extension which allows you to show/add/edit/delete datasets in the frontend.

Answer 1

Call the detach or removeAll methods to remove certain or all objects of the storage.

/** @var \Tx_Extbase_Persistence_ObjectStorage $organisationPartners */
$organisationPartners = $organisation->getPartner();
foreach ($organisationPartners as $partner) {
   $organisationPartners->detach($partner);
}

Answer 2

Thank you @Wolfgang for your message.

I added the following function to my model:

/**
* detach Partner
*
* @param Tx_Toco3Marketingdb_Domain_Model_Partner $partner
* @return void
*/
public function detachPartner($partner) {
   $this->partner->detach($partner);
} 

In the controller I added:

$persistanceManager = t3lib_div::makeInstance('Tx_Extbase_Persistence_Manager');
 $organisation = $this->firmaRepository->findByUid($uid);

$organisationPartners = $organisation->getPartner();
 foreach ($organisationPartners as $organisationPartner) {
     $organisation->detachPartner($organisationPartner);
 }
 $persistanceManager->persistAll();

 $organisation->setPartner($partner);

It is important to persist before setting the new (empty) value...
