我有一个看起来有点难以描述的问题，但无论如何我都会尝试。

在我的 MatchesResultscontroller 中，我有以下代码来构建一个实体：

$em             = $this->getServiceLocator()->get('Doctrine\ORM\EntityManager');    
if($this->getRequest()->isPost()) {

        // get id of current match
        $match_id       = (int)$this->params()->fromRoute('match', 1);

        // find match based on current match id
        $results        = $em->getRepository('Competitions\Entity\MatchesResults')->findBy(
        ['match_id' => $match_id]
        );

        $matchresults = new \Competitions\Entity\MatchesResults();

        // Input
        $matchresults->stek             = $this->getRequest()->getPost('Res_Stek');
        $matchresults->member_id        = $this->getRequest()->getPost('Res_Name');
        $matchresults->weight           = $this->getRequest()->getPost('Res_Gewicht');
        $matchresults->points           = $this->getRequest()->getPost('Res_Punten');
        $matchresults->match_id         = $match_id;
        $matchresults->amount           = $this->getRequest()->getPost('Res_Aantal');

        // Add
        $em->persist($matchresults);
        $em->flush($matchresults);

        // Redirect back to the competition overview
        return $this->redirect()->toRoute('admin-match');

MatchesResults.php 文件看起来像这样

 <?php
namespace Competitions\Entity;

use Doctrine\ORM\Mapping as ORM;

/**  
@ORM\Table()
@ORM\Entity
@ORM\Table(name="matches_results") 
*/

class MatchesResults {
/**
 * @ORM\Id
 * @ORM\GeneratedValue(strategy="AUTO")
 * @ORM\Column(type="integer")
 */
public $id;

/** @ORM\Column(type="integer") */
public $match_id;

/** @ORM\Column(type="integer") */
public $member_id;

/** @ORM\Column(type="integer") */
public $stek;

/** @ORM\Column(type="integer") */
public $weight; 

/** @ORM\Column(type="integer") */
public $amount;

/** @ORM\Column(type="float") */
public $points;

/** @ORM\Column(type="integer") */
public $position;

public $var;

/**
 * @ORM\OneToMany(targetEntity="Competitions\Entity\Matches", mappedBy="Members")
 * @ORM\JoinColumn(name="match_id", referencedColumnName="id")
 */
public $result;

public function getResult() {
    return $this->result;
}

/**
 * @ORM\OneToOne(targetEntity="Members\Entity\Members")
 * @ORM\JoinColumn(name="member_id", referencedColumnName="user_id")   <----- problem here
 */
public $member;

public function getMember() { 
    return $this->member; 
}
}

当我需要对给定匹配的所有结果进行概览时，将正确的用户链接到该结果，它可以完美运行。但是，当我需要添加新结果时，我得到一个 member_id = null，因为教义试图获取一个不存在结果的 member_id。

            $matchresults->stek             = $this->getRequest()->getPost('Res_Stek');
        $matchresults->member_id        = $this->getRequest()->getPost('Res_Name');
        $matchresults->weight           = $this->getRequest()->getPost('Res_Gewicht');
        $matchresults->points           = $this->getRequest()->getPost('Res_Punten');
        $matchresults->match_id         = $match_id;
        $matchresults->amount           = $this->getRequest()->getPost('Res_Aantal');

此代码确实将所有值正确设置到实体中，但实体 member_id 字段仅被覆盖。我将如何解决这个问题？我可以制作一个不包含令人不安的行的单独文件，但我认为这不是一个非常优雅的解决方案。
