Question

我正在使用symfony 3.4。

我有一个链接到实体campagne（campaign）的实体用户（一对多），当我想添加新的campagne时会显示此错误：

使用参数[“ ycamp2”，null]执行'INSERT INTO compagne（desc，user_id）VALUES（？，？）'时发生异常：

SQLSTATE [23000]：违反完整性约束：1048列'user_id'不能为空

坎帕涅类：

class Campagne
{
/**
 * @var int
 *
 * @ORM\Column(name="id", type="integer")
 * @ORM\Id
 * @ORM\GeneratedValue(strategy="AUTO")
 */
public $id;

/**
 * @var string|null
 *
 * @ORM\Column(name="desc", type="string", length=255, nullable=true, unique=true)
 *
 */
private $desc;


/**
* @ORM\ManyToOne(targetEntity="XxBundle\Entity\User", inversedBy="campagnes") 
* @ORM\JoinColumn(nullable=false)
*/
private $user;

//...
/**
 * Set user.
 *
 * @param \XxBundle\Entity\User $user
 *
 * @return Campagne
 */
public function setUser(\XxBundle\Entity\User $user)
{
    $this->user = $user;

    return $this;
}

/**
 * Get user.
 *
 * @return \XxBundle\Entity\User
 */
public function getUser()
{
    return $this->user;
}
}

班级用户：

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

//...

/**

 */    
private $campagnes;

Answer 1

您在数据库表上遇到了NOT NULL约束。您要么需要更改表以允许插入空值，要么确保您始终在请求中传递user_id。

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