Symfony ManyToOne关系SQL错误

我想在我的数据库中写下交易。因此,我有一个TransactionEntity,其字段为'initiator'。该字段应该是用户的userId,负责事务。为了实现这一点,我在TransactionEntity中添加了ManyToOne关系,但每次尝试插入新对象时,都会出现SQL错误。

这是我的用户实体类:

/**
 * @ORM\Table(name="abistuff_users")
 * @ORM\Entity()
 */
class User implements AdvancedUserInterface, \Serializable
{
    /**
    * @ORM\Column(type="integer")
    * @ORM\Id
    * @ORM\GeneratedValue(strategy="AUTO")
    */
    private $id;

    /**
     * @ORM\Column(type="string", length=25, unique=true)
     * @Assert\NotBlank()
     */
    private $username;

    /**
     * @ORM\Column(type="string", length=64)
     * @Assert\NotBlank()
     */
    private $password;

    /**
     * @ORM\Column(type="string", length=60)
     * @Assert\NotBlank()
     */
    private $displayname;

    /**
     * @ORM\Column(type="json_array")
     * @Assert\NotBlank()
     */
    private $roles;

    /**
     * @ORM\Column(name="is_active", type="boolean")
     * @Assert\NotBlank()
     */
    private $isActive;

    /**
     * @ORM\Column(name="is_visible", type="boolean")
     * @Assert\NotBlank()
     */
    private $isVisible;

    //Getters, Setters, and more stuff required for login

}

然后我有我的交易实体类:

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

    /**
     * @ORM\Column(type="integer")
     * @Assert\NotBlank()
     */
    private $value;

    /**
     * @ORM\Column(type="text")
     * @Assert\NotBlank()
     */
    private $usage;

    /**
     * @ORM\Column(type="date")
     * @Assert\NotBlank()
     */
    private $date;

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

这是我创建表单的函数,我尝试插入对象。

public function showAction(Request $request)
    {
        $form = $this->createFormBuilder()
            ->setMethod("POST")
            ->add('value', NumberType::class, array(
                'label' => 'Wert',
                'attr' => array('placeholder' => 'z.B. "10" oder "-5"', 'autofocus' => ''),
                'scale' => 2
            ))
            ->add('usage', TextareaType::class, array(
                'label' => 'Verwendungszweck',
                'attr' => array('placeholder' => 'Ich musste ganz dringend ganz viele Kekse kaufen...')
            ))
            ->add('date', DateType::class, array(
                'label' => 'Datum',
                'widget' => 'single_text',
                'format' => 'dd.MM.yyyy',
                'attr' => array('id' => 'form_date')
            ))
            ->add('initiator', EntityType::class, array(
                'class' => 'AppBundle:User',
                'query_builder' => function(EntityRepository $er){
                    return $er->createQueryBuilder('u')
                        ->where('u.isVisible = 1')
                        ->orderBy('u.displayname', 'ASC');
                },
                'choice_label' => 'displayname',
                'label' => 'Wer ist dafür verantwortlich?'
            ))
            ->add('submit', SubmitType::class, array(
                'label' => 'Transaktion hinzufügen',
                'attr' => array('class' => 'btn-success')
            ))
            ->getForm();

        $form->handleRequest($request);

        if($form->isSubmitted() && $form->isValid())
        {
            //Daten aus der Form holen
            $data = $form->getData();

            //Transaction-Objekt bauen
            $transaction = new BankTransaction();
            $transaction->setValue($data['value']);
            $transaction->setUsage($data['usage']);
            $transaction->setDate($data['date']);
            $transaction->setInitiator($data['initiator']);

            //dump($transaction);
            //die();

            //In die DB schreiben
            $em = $this->getDoctrine()->getManager();
            $em->persist($transaction);
            $em->flush();

            $this->addFlash('success', 'Neue Transaktion über ' . $transaction->getValue() . ' wurde notiert!');
        }

        return $this->render('/abistuff/user/bank/newtransaction.html.twig', array('form' => $form->createView()));
    }

这是我尝试在数据库中写入的对象的转储:

BankTransaction {#1145 ▼
  -id: null
  -value: 10.0
  -usage: "Cookies"
  -date: DateTime {#680 ▼
    +"date": "2017-10-23 00:00:00.000000"
    +"timezone_type": 3
    +"timezone": "UTC"
  }
  -initiator: User {#805 ▼
    -id: 2
    -username: "user"
    -password: "$2y$13$h7oYgYPS5aN.kJBk7ve8jO.AmQJSKhcvT0qNhPO2Lk6p88c2.j1xG"
    -displayname: "Benutzer"
    -roles: array:1 [▶]
    -isActive: true
    -isVisible: true
  }
}

但是当我尝试持久保存此对象然后尝试刷新它时,它会抛出此错误:

  

未捕获的PHP异常Doctrine \ DBAL \ Exception \ SyntaxErrorException:   “执行'INSERT INTO时发生异常   abistuff_transactions(value,usage,date,user_id)VALUES(?,?,?,   ?)'with params [10,“Cookies”,“2017-10-23”,2]:SQLSTATE [42000]:   语法错误或访问冲突:1064 SQL中有错误   句法;检查与MariaDB服务器对应的手册   在'usage,date,user_id)VALUES附近使用正确语法的版本   (10,'Cookies','2017-10-23',2)'在第1行“at   /home/fatih/PhpstormProjects/Abistuff-Symfony4/vendor/doctrine/dbal/lib/Doctrine/DBAL/Driver/AbstractMySQLDriver.php   第90行

有人能帮助我吗?

编辑:我不知道“使用”是保留的。

这是因为usagereserved word你不能使用它。更改字段的名称,如:

/**
 * @ORM\Column(type="text", name="transaction_usage")
 * @Assert\NotBlank()
 */
private $usage;

或逃避它:

/**
 * @ORM\Column(type="text", name="`usage`")
 * @Assert\NotBlank()
 */
private $usage;
