我有一个RequestForEstimate实体，在我的逻辑中的某个时刻到达我创建PurchaseOrder的点，我需要在PurchaseOrder表中插入一个RequestId。我通过使用学说中的一对一关联来参考它。由于某种原因，DB调用成功，但是当我检查表时，看起来request_estimate_id字段为null。这是我的逻辑：

我将从我的一个项目中给你一个例子。整个技巧是实体设置器和级联器配置。 希望它会有所帮助。
实体：
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;
}
}
控制器：
if (null === $agreement->getRequisites()) {
$agreement->setRequisites(new Requisites());
}
$entityManager = $this->getDoctrine()->getManager();
$entityManager->persist($agreement);
$entityManager->flush();
