Php Symfony可选电话输入验证完整性错误：列'；电话'；不能为空

我拥有以下实体：

namespace AppBundle\Entity;

use Doctrine\ORM\Mapping as ORM;
use FOS\UserBundle\Model\User as BaseUser;
use Symfony\Component\Validator\Constraints as Assert;
use Misd\PhoneNumberBundle\Validator\Constraints\PhoneNumber as AssertPhoneNumber;

/**
 * @ORM\Entity
 * @ORM\Table(name="users")
 */
class User extends BaseUser
{
    /**
     * @ORM\Column(type="integer")
     * @ORM\Id
     * @ORM\GeneratedValue(strategy="AUTO")
     */
    protected $id;

    /**
     * @ORM\Column(type="string", length=25)
     * @Assert\NotBlank(message="Please enter your name.", groups={"Registration", "Profile"})
     * @Assert\Length(
     *     min=3,
     *     max=25,
     *     minMessage="The name is too short.",
     *     maxMessage="The name is too long.",
     *     groups={"Registration", "Profile"}
     * )
     */
    protected $name;

    /**
     * @ORM\Column(type="string", length=25)
     * @Assert\NotBlank(message="Please enter your name.", groups={"Registration", "Profile"})
     * @Assert\Length(
     *     min=3,
     *     max=25,
     *     minMessage="The surname is too short.",
     *     maxMessage="The surname is too long.",
     *     groups={"Registration", "Profile"}
     * )
     */
    protected $surname;

    /**
     * @ORM\Column(type="phone_number")
     * @AssertPhoneNumber
     */
    protected $phone;

    /**
     * @ORM\Column(type="string", length=255)
     * @Assert\Length(
     *     min=0,
     *     max=255,
     *     groups={"Registration", "Profile"}
     * )
     */
    protected $organization;

    /**
     * @ORM\Column(type="string", length=255)
     * @Assert\Length(
     *     min=0,
     *     max=255,
     *     groups={"Registration", "Profile"}
     * )
     */
    protected $occupation;

    public function __construct()
    {
        parent::__construct();
    }

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

      return $this;
    }

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


    public function setSurname(string $surname)
    {
      $this->surname=$surname;

      return $this;
    }

    public function getSurname()
    {
        return $this->name;
    }

    public function setPhone($phoneNum)
    {
      $this->phone=$phoneNum;
      return $this;
    }

    public function getPhone()
    {
      return $this->phone;
    }

    public function setOrganization($organization)
    {
      $this->organization=$organization;
      return $this;
    }

    public function getOrganization()
    {
      return $this->organization;
    }

    public function setOccupation($occupation)
    {
      $this->occupation=$occupation;
      return $this;
    }

    public function getOccupation()
    {
      return $this->occupation;
    }
}

如您所见，它有一个名为

$phone

的字段：

/**
 * @ORM\Column(type="phone_number")
 * @AssertPhoneNumber
 */
protected $phone;

按照我的逻辑，该字段应该是可选的，不需要注册，因此为了做到这一点，我相应地扩展了FosUserBundle表单：

namespace AppBundle\Form;

use Symfony\Component\Form\AbstractType;
use Symfony\Component\Form\FormBuilderInterface;
use Symfony\Component\Form\Extension\Core\Type\TextType;
use Misd\PhoneNumberBundle\Form\Type\PhoneNumberType;
use Symfony\Component\Form\Extension\Core\Type\CheckboxType;


class RegistrationType extends AbstractType
{
    public function buildForm(FormBuilderInterface $builder, array $options)
    {
        $builder->add('name',TextType::class,["label"=>"register.name","required"=>true,'translation_domain' => 'FOSUserBundle'])
                ->add('surname',TextType::class,["label"=>"register.surname","required"=>true,'translation_domain' => 'FOSUserBundle'])
                ->add('phone',PhoneNumberType::class,["label"=>"register.phonenum",'translation_domain' => 'FOSUserBundle'])
                ->add('organization',TextType::class,["label"=>"register.organization","required"=>false,'translation_domain' => 'FOSUserBundle'])
                ->add('occupation',TextType::class,["label"=>"register.position","required"=>false,'translation_domain' => 'FOSUserBundle']);
    }

    public function getParent()
    {
        return 'FOS\UserBundle\Form\Type\RegistrationFormType';
    }

    public function getBlockPrefix()
    {
        return 'app_user_registration';
    }

    // For Symfony 2.x
    public function getName()
    {
        return $this->getBlockPrefix();
    }
}

如您所见，我将其设置为NotRequired，如您在以下代码段中所见：

->add('phone',PhoneNumberType::class,["label"=>"register.phonenum",'translation_domain' => 'FOSUserBundle'])

但是，当我尝试测试注册时，会出现以下错误：

SQLSTATE[23000]：完整性约束冲突：1048列“phone”不能为null

为了避免此类错误，我还将定义更改为：

/**
 * @ORM\Column(type="phone_number")
 */
protected $phone;

但我仍然得到了错误。是一种将字段设置为null的方法吗

同样为了验证，我使用了php的

giggsey/libphonenumber

coposer包

/**
* @ORM\Column(type="phone_number", nullable=true)
* @AssertPhoneNumber
*/
protected $phone;

---

我相信这会奏效

条令注释中缺少一个参数：

/**
 * @ORM\Column(type="phone_number", nullable=true)
 * @AssertPhoneNumber
 */
protected $phone;

不要忘记运行

d:s:u--dump sql |--force

或生成迁移；）
