我在这两个表的 userId 字段之间有一个简单的 ManyToOne 关系。

这是我尝试使用原则将数据添加到数据库中的代码。

public function checkDatabaseAction(){
            
            $user = new Users();
            $user->setDateString(date('Y-m-d'))
                ->setDateTimeString(date('Y-m-d H:i:s'))
                ->setIsActive(1)
                ->setIsDeleted(0)
                ->setIsEditable(1)
                ->setIsTwoWayAuthEnabled(0)
                ->setLastUpdatedOn(date('Y-m-d H:i:s'))
                ->setSchoolId(1)
                ->setSlug('abc-123')
                ->setTokkenExpiryTime(date('Y-m-d'))
                ->setUpdatedBy(1)
                ->setUsername('ahmedali5530')
                ->setVerificationPin('1122')
                ->setVerificationTokken('hskajdhfkjlh435kh34k5jh435');
            
            $log = new ActivitLogs();
            $log->setActivityLog('A log')
                ->setDateString(date('Y-m-d'))
                ->setDateTimeString(date('Y-m-d H:i:s'))
                ->setIpAddress('192.168.1.16')
                ->setIsActive(1)
                ->setIsDeleted(0)
                ->setIsEditable(1)
                ->setLastUpdatedOn(date('Y-m-d H:i:s'))
                ->setOsPlatform('Windows 7')
                ->setReferer('http://localhost/symfony')
                ->setSchoolId(1)
                ->setUpdatedBy(1)
                ->setUserAgent('Chrome')
                ->setUserId($user);
            
            
            $em = $this->getDoctrine()->getManager();
               
            $em->persist($user);
            $em->persist($log);
            
            
            $em->flush();
            
            $allocateCourses = $em->getRepository('AppBundle:AllocateCourses')->findBy(array('isActive'=>1));
            
            return $this->render(':main:form.html.php',array(
                'data' => $allocateCourses,
            ));
        }

当我执行这段代码时，我收到了错误：-

An exception occurred while executing 'INSERT INTO ms_activity_logs (user_id, activity_log, user_agent, os_platform, ip_address, referer, date_string, date_time_string, is_active, is_deleted, is_editable, last_updated_on, school_id, updated_by) VALUES (?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?)' with params [{}, "A log", "Chrome", "Windows 7", "192.168.1.16", "http://localhost/symfony", "2015-12-22", "2015-12-22 16:53:55", 1, 0, 1, "2015-12-22 16:53:55", 1, 1]:

关于如何修复此错误的任何建议。

Answer 1

好的，我得到了答案。

我在 ActivityLogs.php 中添加了新的私有属性并告诉 Doctrine 生成实体。 Doctrine 创建了 getter 并为此设置了属性。这解决了我的问题。

这是我添加的代码：

/**
 * @ORM\ManyToOne(targetEntity="Users", inversedBy="ActivityLogs")
 * @ORM\JoinColumn(name="user_id", referencedColumnName="id")
 */
private $user;
