Hey guys so I have 2 entities with a bidirectional OneToOne relationship:
Sale.php
/**
* @var TransportInvoice
*
* @ORM\OneToOne(targetEntity="WKDA\Common\Entity\Car\TransportInvoice\TransportInvoice", mappedBy="sale")
* @ORM\JoinColumn(name="transport_invoice", referencedColumnName="id", nullable=true, onDelete="SET NULL")
*/
protected $transportInvoice;
TransportInvoice.php
/**
* @var Sale
* @ORM\OneToOne(targetEntity="WKDA\Common\Entity\Car\Sale", inversedBy="transportInvoice", cascade={"persist"}, orphanRemoval=true)
* @ORM\JoinColumn(name="sale", referencedColumnName="id", nullable=false)
*/
protected $sale;
In my controller, to delete a transport invoice from the sale, the following is done:
$transportInvoice = $car->getSale()->getTransportInvoice();
$em = $this->getEntityManager();
$em->remove($transportInvoice);
$em->flush();
This deletes the TransportInvoice, but it deletes the Sale object as well. I don't want the Sale object to be deleted, I just want the TransportInvoice parameter within sale to be null. What am I not understanding?
If this is not clear let me know, thanks for your help!
