Question

我的数据库中有这两个表：

REF_PARAM(id, label)
DECLARATION(number, status)

＆＃39;状态＆＃39;是REF_PARAM的外键。

我用命令行生成我的实体。我有2个实体RefParam和声明：

当持久化Statement对象时，我有一个例外：

A new entity was found that was not configured to cascade persist operations for entity RefParam

当然，我不想坚持使用RefParam，因为所有状态都已存在于数据库中。所以，我不确定我是对的，我想使用mappedBy属性来表示我想在DECLARATION表中保留声明时使用RefParam的id。所以我补充道：

/**
 * @var \RefParam
 *
 * @ORM\ManyToOne(targetEntity="RefParam", mappedBy="id")
 * @ORM\JoinColumns({
 *   @ORM\JoinColumn(name="STATUS", referencedColumnName="ID")
 * })
 */

我有另一个例外：

 The annotation @ORM\ManyToOne does not have a property named "mappedBy"

看起来它更倾向于我可以使用ManyToOne关系。它没有解决我的问题。

我的问题是：

如何持久化Statement对象并将RefParam对象的id放在状态列中？

    return $entity_declaration;

Answer 1

当您获得fromModelClass对象时，RefParam中的问题就出现了这一行：

$refParamStatut = new \Cramif\AccueilBundle\Entity\RefParam();

从Doctrine的角度来看，statut被设置为一个前所未有的全新对象。当你持久$declaration_entity时，它知道它的RefParam是一个实体而不是数据库中的实体，所以它会抱怨。你要么自己坚持下去，要么坚持级联，所以Doctrine会为你做，或者，这可能是你的情况下的答案，因为你不想做任何新的RefParam，取得正确的首先是来自DB的RefParam对象（然后它根本不需要持久化）。

e.g。

fromModelClass

$refParamStatut = $paramRepository->find($declaration->getStatut()->getId());

持久性（NB现在与您的示例相同，因为$ declaration-＆gt; refParamStatut是一个托管实体）

$param = new Param(2); //POPO model
$declaration->setStatut($param);

//Within fromModelClass $param gets turned into a managed RefParam Entity, which doesn't need persisting
$declaration_entity = DeclarationRepository::fromModelClass($declaration);

$em = $this->getDoctrine()->getManager();
$em->persist($declaration_entity);
$em->flush(); //No exception

Answer 2

您在线分配新对象：

$declaration->setStatut(new Param(2));

这不是由Doctrine管理的，这就是为什么它要坚持下去。

您可以设置参考：

，而不是使用从DB中提取的数据

$declaration->setStatut($em->getReference('App\AcmeBUndle\Entity\Param', 2));
