Question

我需要Symfony2（2.8）的帮助

创建了两个实体Category和CategoryLang。这将是一个类别。

<?php

namespace CreLabs\Bundle\SettingBundle\Entity;

use Doctrine\ORM\Mapping as ORM;
use Doctrine\ORM\Mapping\Entity;

/**
 * @ORM\Entity(repositoryClass="CreLabs\Bundle\SettingBundle\Entity\CategoryRepository")
 * @ORM\Table(name="category")
 */
class Category
{

    const STATUS_ENABLED = 1;
    const STATUS_DISABLED = 0;

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

    /**
     * @ORM\Column(type="boolean", nullable=true, options={"default": 1})
     */
    protected $status;

    /**
     * @ORM\OneToMany(targetEntity="CategoryLang", mappedBy="category", cascade={"persist", "remove"})
     */
    protected $locales;

    /**
     * @ORM\Column(type="datetime", nullable=false)
     */
    protected $created_at;

    /**
     * @ORM\Column(type="datetime", nullable=true)
     */

    /**
     * @ORM\Column(type="datetime", nullable=true)
     */
    protected $updated_at;

CategoryLang。它将是我的类别的翻译。

<?php

namespace CreLabs\Bundle\SettingBundle\Entity;

use Doctrine\ORM\Mapping as ORM;
use Doctrine\ORM\Mapping\Entity;

/**
 * @Entity
 * @ORM\Table(name="category_lang")
 */
class CategoryLang
{

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

    /**
     * @ORM\Column(type="string", length=255)
     */
    protected $name;

    /**
     * @ORM\Column(type="string", length=255, nullable=true)
     */
    protected $description;

    /**
     * @ORM\ManyToOne(targetEntity="Category", inversedBy="locales", cascade={"persist", "remove"})
     * @ORM\JoinColumn(name="category_id", referencedColumnName="id")
     */
    protected $category;

    /**
     * @ORM\Column(type="string", length=2)
     */
    protected $locale;

现在我尝试添加createFormBuilder类别实体+ CategoryLang实体字段，但无法正常查看表单。只能使用数组（＆＃39;映射＆＃39; =＆gt; false并转发来自字段的数据。

$form = $this->createFormBuilder($category);
        $form = $form
            ->add('locale', HiddenType::class, array('mapped' => false, 'data' => $locale))
            ->add('name', TextType::class, array('mapped' => false, 'data' => $name))
            ->add('description', TextareaType::class, array('mapped' => false, 'required' => false, 'data' => $description))
            ->add($label, SubmitType::class, array('label' => $label));
        $form = $form->getForm();

顺便说一下，ClassRepository有自定义查询

public function getCategory($category_id, $locale)
    {
        $repository = $this->getEntityManager()->getRepository('SettingBundle:Category');
        $fields = array('p.id', 'category_info.name', 'category_info.description', 'p.status, category_info.locale');
        $query = $repository->createQueryBuilder('p')
            ->select($fields)
            ->innerJoin('SettingBundle:CategoryLang', 'category_info', 'WITH', 'category_info.category = p.id')
            ->where('p.id = :category_id AND category_info.locale = :locale')
            ->setParameter('category_id', $category_id)
            ->setParameter('locale', $locale)
            ->getQuery();

        $result = $query->getOneOrNullResult() != NULL ? new ArrayCollection($query->getSingleResult()) : false;

        return $result;
    }

问题： 1. getCategory（） - ＆gt; return not object，但是array或ArrayCollection。无法重用然后需要更新数据库中的字段。

/* @var $category Category */
        $category = $this->getCategory($category_id, $form['locale']);

        if ($category) {
//            $category->setUpdatedAt(new ArrayCollection());
            $locale = new CategoryLang();
            $locale->setName($form['name']);
            $locale->setDescription($form['description']);
            $category->addLocale($locale);
            $entityManager = $this->getEntityManager();
            $entityManager->persist($category);
            $entityManager->flush($category);
        }

2。无法从子表中获取创建表单构建器信息。

我的问题在哪里？任何人都可以帮我理解我的错误吗？
