来自子实体的字段不显示在symfony中

我为一个noob问题提前道歉。我刚开始学习symfony，遇到了障碍。我创建了RequestForEstimate实体，它可能有多个与RequestForEstimateDetail实体关联的记录。现在，我试图创建一个表单，不仅显示第一个实体的字段，还显示第二个实体的字段。 Symfony不会返回任何错误，但它不会呈现RequestForEstimateDetail实体中的“数量”字段。我用下面的教程来创建此代码：How to Embed a Collection of Forms 来自子实体的字段不显示在symfony中

这是我RequestForEstimate实体的例子：

<?php 

namespace SourcingBundle\Entity; 

use Doctrine\ORM\Mapping as ORM; 

/** 
* RequestForEstimate 
* 
* @ORM\Table(name="request_for_estimate") 
* @ORM\Entity(repositoryClass="SourcingBundle\Repository\RequestForEstimateRepository") 
*/ 
class RequestForEstimate 
{ 
    /** 
    * @var int 
    * 
    * @ORM\Column(name="requestId", type="integer") 
    * @ORM\Id 
    * @ORM\GeneratedValue(strategy="AUTO") 
    */ 

    private $id; 

    /** 
    * @var int 
    * 
    * @ORM\Column(name="status", type="integer") 
    */ 
    private $status; 

    /** 
    * @var \DateTime 
    * 
    * @ORM\Column(name="createTime", type="datetime") 
    */ 
    private $createTime; 

    /** 
    * @var \DateTime 
    * 
    * @ORM\Column(name="updateTime", type="datetime") 
    */ 
    private $updateTime; 

    /** 
    * @var string 
    * 
    * @ORM\Column(name="name", type="string", length=255) 
    */ 
    private $name; 
    /** 
    * @ORM\OneToMany(targetEntity="RequestForEstimateDetail", mappedBy="detail", cascade={"persist", "remove"}, orphanRemoval=true) 
    */ 
    private $details; 

    /** 
    * Get id 
    * 
    * @return int 
    */ 
    public function getId() 
    { 
     return $this->id; 
    } 

    /**

    * 
    * @param integer $status 
    * 
    * @return RequestForEstimate 
    */ 
    public function setStatus($status) 
    { 
     $this->status = $status; 

     return $this; 
    } 

    /** 
    * Get status 
    *

    public function getStatus() 
    { 
     return $this->status; 
    } 

    /** 
    * Set createTime 
    * 
    * @param \DateTime $createTime 
    * 
    * @return RequestForEstimate 
    */ 
    public function setCreateTime($createTime) 
    { 
     $this->createTime = $createTime; 

     return $this; 
    } 

    /** 
    * Get createTime 
    * 
    * @return \DateTime 
    */ 
    public function getCreateTime() 
    { 
     return $this->createTime; 
    } 

    /** 
    * Set updateTime 
    * 
    * @param \DateTime $updateTime 
    * 
    * @return RequestForEstimate 
    */ 
    public function setUpdateTime($updateTime) 
    { 
     $this->updateTime = $updateTime; 

     return $this; 
    } 

    /** 
    * Get updateTime 
    * 
    * @return \DateTime 
    */ 
    public function getUpdateTime() 
    { 
     return $this->updateTime; 
    } 

    /** 
    * Set name 
    * 
    * @param string $name 
    * 
    * @return RequestForEstimate 
    */ 
    public function setName($name) 
    { 
     $this->name = $name; 

     return $this; 
    } 

    /** 
    * Get name 
    * 
    * @return string 
    */ 
    public function getName() 
    { 
     return $this->name; 
    } 
    /** 
    * Constructor 
    */ 
    public function __construct() 
    { 
     $this->details = new \Doctrine\Common\Collections\ArrayCollection(); 
    } 

    /** 
    * Add detail 
    * 
    * @param \SourcingBundle\Entity\RequestForEstimateDetail $detail 
    * 
    * @return RequestForEstimate 
    */ 
    public function addDetail(\SourcingBundle\Entity\RequestForEstimateDetail $detail) 
    { 
     $this->details[] = $detail; 

     return $this; 
    } 

    /** 
    * Remove detail 
    * 
    * @param \SourcingBundle\Entity\RequestForEstimateDetail $detail 
    */ 
    public function removeDetail(\SourcingBundle\Entity\RequestForEstimateDetail $detail) 
    { 
     $this->details->removeElement($detail); 
    } 

    /** 
    * Get details 
    * 
    * @return \Doctrine\Common\Collections\Collection 
    */ 
    public function getDetails() 
    { 
     return $this->details; 
    } 
}

这是我RequestForEstimateDetail实体：

<?php 

namespace SourcingBundle\Entity; 

use Doctrine\ORM\Mapping as ORM;

    private $id;

    */ 
    public function getDetail() 
    { 
     return $this->detail; 
    } 
}

这是我RequestForEstimateController：

<?php 

namespace SourcingBundle\Controller; 

use SourcingBundle\Entity\RequestForEstimate; 
use SourcingBundle\Form\Type\RequestForEstimateType; 
use Symfony\Bundle\FrameworkBundle\Controller\Controller; 
use Symfony\Component\HttpFoundation\Request; 
use Symfony\Component\Form\Extension\Core\Type\TextType; 
use Symfony\Component\Form\Extension\Core\Type\DateType; 
use Symfony\Component\Form\Extension\Core\Type\CollectionType; 
use Symfony\Component\Form\Extension\Core\Type\SubmitType; 
use Sensio\Bundle\FrameworkExtraBundle\Configuration\Route; 

class RequestForEstimateController extends Controller 
{ 
/** 
    * @Route("sourcing/request-for-estimate", name="request_for_estimate") 
    */ 
    public function addRequest(Request $request) 
    { 

     $RequestForEstimate = new RequestForEstimate(); 
     $form = $this->createForm(RequestForEstimateType::class, $RequestForEstimate); 

     return $this->render('sourcing/requestforestimate/create.html.twig', array(
      'form' => $form->createView(), 
     )); 
    } 
}

这些是我的f ORM类：

RequestForEstimateType.php

<?php 
namespace SourcingBundle\Form\Type; 

use Symfony\Component\Form\AbstractType; 
use Symfony\Component\Form\FormBuilderInterface; 
use Symfony\Component\OptionsResolver\OptionsResolver; 
use Symfony\Component\Form\Extension\Core\Type\TextareaType; 
use Symfony\Component\Form\Extension\Core\Type\EmailType; 
use Symfony\Component\Form\Extension\Core\Type\DateTimeType; 
use Symfony\Component\Form\Extension\Core\Type\CollectionType; 

class RequestForEstimateType extends AbstractType 
{ 
    public function buildForm(FormBuilderInterface $builder, array $options) 
    { 
     $builder->add('name'); 
     $builder->add('details', CollectionType::class, array(
      'entry_type' => RequestForEstimateDetailType::class 
     )); 
    } 

    public function configureOptions(OptionsResolver $resolver) 
    { 
     $resolver->setDefaults(array(
      'data_class' => 'SourcingBundle\Entity\RequestForEstimate', 
     )); 
    } 
}

RequestForEstimateDetailType.php：

<?php 
namespace SourcingBundle\Form\Type; 

use Symfony\Component\Form\AbstractType; 
use Symfony\Component\Form\FormBuilderInterface; 
use Symfony\Component\OptionsResolver\OptionsResolver; 

class RequestForEstimateDetailType extends AbstractType 
{ 
    public function buildForm(FormBuilderInterface $builder, array $options) 
    { 
     $builder->add('quantity',TextType::class); 
    } 

    public function configureOptions(OptionsResolver $resolver) 
    { 
     $resolver->setDefaults(array(
      'data_class' => 'SourcingBundle\Entity\RequestForEstimateDetail', 
     )); 
    } 
}

现在我的观点：

<div class="row"> 
    <div class="col-sm-12"> 
     <div class="ibox float-e-margins"> 
      <div class="ibox-title"> 
       <h5>Create Request For Estimate</h5> 
      </div> 
      <div class="ibox-content"> 
       {{ form_start(form) }} 
        {{ form_errors(form) }} 

        <div> 
         {{ form_widget(form) }} 
        </div> 
        {{ dump(form.details)}} 

        {% for detail in form.details %} 
         <li>{{ form_row(detail.quantity) }}</li> 
        {% endfor %} 

       {{ form_end(form) }} 
      </div> 

     </div> 
    </div> 
</div>

你需要在你的控制器类来创建一些RequestForEstimateDetail实体并将其添加到RequestForEstimate实体。像这样：

class RequestForEstimateController extends Controller 
{ 
    /** 
    * @Route("sourcing/request-for-estimate", name="request_for_estimate") 
    */ 
    public function addRequest(Request $request) 
    { 
     $RequestForEstimate = new RequestForEstimate(); 
     $detail1 = new RequestForEstimateDetail(); 
     $detail2 = new RequestForEstimateDetail(); 
     $RequestForEstimate->addDetail($detail1); 
     $RequestForEstimate->addDetail($detail2);    

     $form = $this->createForm(RequestForEstimateType::class, $RequestForEstimate); 

     return $this->render('sourcing/requestforestimate/create.html.twig', array(
      'form' => $form->createView(), 
     )); 
    } 
}

PS。你可以阅读这个文档http://symfony.com/doc/current/form/form_collections.html它很清楚=）
