Question

我有点问题。

我收到此错误

在AppBundle \ Entity \ User
上缺少主键ID的值

这是我对数据库的实现

这是我的实体

 /**
 * @ORM\Entity
 * @ORM\Table(name="caller_machine")
 */
class CallerMachine {

/**
 * @ORM\GeneratedValue(strategy="AUTO")
 * @ORM\Id
 * @ORM\Column(type="integer")
 */
private $id;

/**
 * @ORM\Column(type="integer", nullable=true)
 */
private $buttonNumber;

/**
 * @ORM\Column(type="text", nullable=false)
 */
private $linkToMusic;

/**
 * @ORM\Column(type="text", nullable=true)
 */
private $telephoneNumber;

/**

private $acceptRegulations;

/**

private $numberMachine;

    private $username;

     */
    private $user;

    /**

    private $linkToMusic;

当我创建表单

时

public function buildForm(FormBuilderInterface $builder, array $options) {
        $builder
                ->add('numbermachine', EntityType::class, [
                    'class' => 'AppBundle\Entity\CallerMachineVoice',
                    'choice_label' => 'user'
                ])
                ->add('buttonnumber', IntegerType::class, [
                    'label' => 'Podaj numer przycisku'
                ])
                ->add('linktomusic', TextType::class,[
                    'label' => 'Podaj link do muzyki'
                ])
                ->add('telephonenumber', IntegerType::class, [
                    'label' => 'Podaj numer przycisku'
                ])
                ->add('acceptregulations', IntegerType::class, [
                    'label' => 'Podaj numer przycisku'
                ])
                ->add('submit', \Symfony\Component\Form\Extension\Core\Type\SubmitType::class, array(
                    'label' => 'Zapisz'
                ));
    }

我有一个问题，但是当我删除行时，numberMachine＆＃39;＆＃39;我看到了我的表格。我的问题在哪里？帮帮我：）

现实化

可能我的问题是实体CallerMachineVoice

Answer 1

试试这个：

在CallerMachineVoice上：

/**
 * @ORM\ManyToOne("User") 
 * @ORM\JoinColumn(
 *      name = "user_id",
 *      referencedColumnName = "id",
 *      nullable = false
 * )
 */
private $user;

然后在User Entity __toString魔术方法上定义：

/**
 * @return string
 */
public function __toString()
{
    return $this->getUsername();
}

缺少主键ID的值
