Symfony和Doctrine MappedSuperClass-固定装置失败

Question

我有这个映射的超级班

/**
 * @ORM\MappedSuperclass()
 */
abstract class Address
{
    /**
     * @ORM\Column(type="string", length=255)
     */
    protected $street;

    /**
     * @ORM\Column(type="string", length=10)
     */
    protected $zipCode;

    /**
     * @ORM\Column(type="string", length=255)
     */
    protected $city;

    /**
     * @ORM\Column(type="string", length=255)
     */
    protected $country;

    public function getStreet(): ?string
    {
        return $this->street;
    }

    public function setStreet(string $street): self
    {
        $this->street = $street;

        return $this;
    }

    public function getZipCode(): ?string
    {
        return $this->zipCode;
    }

    public function setZipCode(string $zipCode): self
    {
        $this->zipCode = $zipCode;

        return $this;
    }

    public function getCity(): ?string
    {
        return $this->city;
    }

    public function setCity(string $city): self
    {
        $this->city = $city;

        return $this;
    }

    public function getCountry(): ?string
    {
        return $this->country;
    }

    public function setCountry(string $country): self
    {
        $this->country = $country;

        return $this;
    }
}

这个Location类的女巫继承了我的Super类：

/**
 * @ApiResource()
 * @ORM\Entity(repositoryClass="App\Repository\LocationRepository")
 */
class Location extends Address
{
    /**
     * @ORM\Id()
     * @ORM\GeneratedValue()
     * @ORM\Column(type="integer")
     */
    private $id;

    /**
     * @ORM\Column(type="string", length=255)
     */
    private $name;

    public function getId(): ?int
    {
        return $this->id;
    }

    public function getName(): ?string
    {
        return $this->name;
    }

    public function setName(string $name): self
    {
        $this->name = $name;

        return $this;
    }
}

我想添加一些装置：

class LocationFixtures extends Fixture
{
    public function load(ObjectManager $manager)
    {
        $events = $manager->getRepository(Event::class)->findAll();
        $faker = Factory::create();

        foreach ($events as $event) {
            $location = new Location();
            $location->setName($faker->streetName);
            $location->setStreet($faker->streetAddress);
            $location->setCity($faker->city);
            $location->setCountry($faker->country);
            $location->setZipCode($faker->postcode);
            $event->setLocation($location);
            $manager->persist($event);
        }

        $manager->flush();
    }
}

但是那些失败并显示以下错误消息：

在使用参数[“ 14549 Mayer Freeway \\ nSengerchester，ME 42242”执行null时，执行“将位置插入到位置（名称，街道，邮政编码，城市，国家/地区）值（？，？，？，？，？）”时发生异常，null，null]：

SQLSTATE [23000]：违反完整性约束：1048列“ street”不能为空

我将街道属性设置在固定装置中，这是什么问题？

谢谢你让我指出了问题所在。 我还在EventFixture中设置了位置。 而正是那些失败者。

我把所有东西都放到了Event Fixture上，并且一切正常

class EventFixtures extends Fixture
{
    public function load(ObjectManager $manager)
    {
        $faker = Factory::create();

        for ($i = 0; $i < 10; $i++) {
            $event = new Event();
            $event->setName($faker->name);
            $event->setDescription($faker->text);
            $dateStart = $faker->dateTime;
            $event->setStartAt($dateStart);
            $event->setFinishAt($dateStart->add(new \DateInterval('P2D')));
            $event->setPrice($faker->numberBetween(20, 200));
            $event->setType(EventType::PHOTOGRAPHY);
            $event->setInstagram($faker->firstName);

            $location = new Location();
            $location->setName($faker->streetName);
            $location->setStreet($faker->streetAddress);
            $location->setCity($faker->city);
            $location->setCountry($faker->country);
            $location->setZipCode($faker->postcode);
            $manager->persist($location);
            $event->setLocation($location);

            $manager->persist($event);
        }

        $manager->flush();
    }
}
