Doctrine not saving a one to one referenced field - symfony

Question

I have a RequestForEstimate entity that at some point in my logic gets to the point where I create a PurchaseOrder and I need to insert a RequestId in the PurchaseOrder table. I have it reference by using the One to One association in doctrine. For some reason the DB call is successful however when I check the table it looks like the request_estimate_id field is null. Here is my logic:
RequestForEstimate entity:
<?php
namespace InboundBundle\Entity;
use Doctrine\ORM\Mapping as ORM;

Answer 1

I will give you an example from one of my projects. The whole trick is in entities setters and cascaders configurations.
Hope it will help.
Entities:
class Agreement
{
// ...
/**
* #ORM\OneToOne(targetEntity="AppBundle\Entity\Requisites", mappedBy="agreement", cascade={"persist"})
*/
private $requisites;
// ...
public function setRequisites(Requisites $requisites = null)
{
$this->requisites = $requisites;
$requisites->setAgreement($this);
return $this;
}
public function getRequisites()
{
return $this->requisites;
}
}
class Requisites
{
// ...
/**
* #ORM\OneToOne(targetEntity="AppBundle\Entity\Agreement", inversedBy="requisites")
* #ORM\JoinColumn(name="Agreement_id", referencedColumnName="id")
*/
private $agreement;
// ...
public function setAgreement(Agreement $agreement = null)
{
$this->agreement = $agreement;
return $this;
}
public function getAgreement()
{
return $this->agreement;
}
}
Controller:
if (null === $agreement->getRequisites()) {
$agreement->setRequisites(new Requisites());
}
$entityManager = $this->getDoctrine()->getManager();
$entityManager->persist($agreement);
$entityManager->flush();
