Php 无法使用条令将数据刷新到子表中

下面是我的代码片段，我试图做的是将父表的ID插入子表，同时将数据插入子表。下面是我的代码片段

public function addAction()
{

    $ViewModel = new ViewModel();
    $form = new TestForm();
    $form->get('submit')->setValue('Add');
    $request = $this->getRequest();
    if ($request->isPost())
    {
        $TestFilter = new TestFilter();
        $test = $this->getServiceLocator()->get('Test');
        $form->setInputFilter($TestFilter->getInputFilter());
        $form->setData($request->getPost());
        if ($form->isValid())
        {

            $test->populate($form->getData());

            $this->getEntityManager()->persist($test);
            $this->getEntityManager()->flush();

            $TestDetail = $this->getServiceLocator()->get('TestDetail');
            $TestDetail->populate($form->getData());
            $TestDetail->setTest($test);
            $this->getEntityManager()->persist($TestDetail);
            $this->getEntityManager()->flush();
            return $this->redirect()->toRoute('test');
        }
    }
    return array('form' => $form);
}

我的实体如下所示

<?php

namespace Test\Entity;

use Doctrine\ORM\Mapping as ORM;
use Zend\Form\Annotation;
use Test\Entity\Test;

查看属性TestDetails:：test

/**
 * @ORM\ManyToOne(targetEntity="TestDetail", inversedBy="test_details")
 * 
 * @Annotation\Required(true)
 */
protected $test;

您正在将目标实体定义为TestDetail（同一类），同时将一个Test实例传递给TestDetails:：setTest（）

---

当您引用测试实体时，您的目标实体应该是Test。请尝试上面提到的代码并告诉我。

经过测试和检查，这是第一次，后来我选择了自引用同一个表的点。

/**
 * @ORM\ManyToOne(targetEntity="TestDetail", inversedBy="test_details")
 * 
 * @Annotation\Required(true)
 */
protected $test;

/**
 * @ORM\ManyToOne(targetEntity="Test", inversedBy="test_details")
 * 
 * @Annotation\Required(true)
*/
protected $test;
