Question

两个表 Utenti 和 Nuclei 相互关联

Utenti SQL

CREATE TABLE public.utentiweb
(
    id bigint NOT NULL,
    username character varying(200),
    password character varying(128),
    idnucleo bigint NOT NULL DEFAULT 0,
)

细胞核SQL

CREATE TABLE public.datinuclei
(
    id integer NOT NULL,
    idcomune integer NOT NULL,
    cognome character varying,
    nome character varying,
)

/**
 * Utentiweb
 *
 * @ORM\Table(name="utentiweb")
 * @ORM\Entity
 */
class Utenti implements UserInterface
{
    /**
     * @var int
     *
     * @ORM\Column(name="id", type="bigint", nullable=false)
     * @ORM\Id
     * @ORM\GeneratedValue(strategy="SEQUENCE")
     * @ORM\SequenceGenerator(sequenceName="utentiweb_id_seq", allocationSize=1, initialValue=1)
     */
    private $id;

    /**
     * @var Nuclei
     *
     * @ORM\OneToOne(targetEntity="Nuclei", mappedBy="utente")
     * @ORM\JoinColumn(name="idnucleo", referencedColumnName="id")
     */
    private $nucleo;

/**
 * Nuclei
 *
 * @ORM\Table(name="datinuclei")
 * @ORM\Entity(repositoryClass="App\Repository\NucleiRepository")
 */
class Nuclei
{
    /**
     * @var int
     *
     * @ORM\Id
     * @ORM\Column(name="id", type="integer", nullable=false)
     * @ORM\GeneratedValue(strategy="NONE")
     */
    private $id;

    /**
     * @var Utenti
     *
     * @ORM\OneToOne(targetEntity="Utenti", inversedBy="nucleo")
     * @ORM\JoinColumn(name="id", referencedColumnName="id")
     */
    private $utente;

从 Utente WORKS 获取 Nucleo

    $utente = $this->getDoctrine()->getRepository(Utenti::class)->find(3078);
    dump($utente->getNucleo()->getNome());

从 Nucleo 获取 Utente 行不通

    $nucleo = $this->getDoctrine()->getRepository(Nuclei::class)->find(5780);
    dump($nucleo->getUtente()->getUsername());

错误：

    Entity of type 'App\Entity\Utenti' for IDs id(5780) was not found

Nuclei关系标注有问题，不知道怎么解决，nuclei.id应该和utenti.idnucleo有关。尝试了很多组合都没有成功

谢谢

更新 JoinColumn 在 Nuclei 实体上删除

An exception occurred while executing 'SELECT t0.id AS id_1,

Answer 1

删除行：

@ORM\JoinColumn(name="id", referencedColumnName="id")

来自classNuclei字段$utent
