我在弄清楚以下问题时遇到了一些问题：当使用表单制作新咖啡店时，如何让 Symfony 插入新菜单？（菜单中的外键是shopid）

在此先感谢，代码如下。

菜单实体：

<?php

namespace AppBundle\Entity;

use Doctrine\ORM\Mapping as ORM;
use Gedmo\Mapping\Annotation as Gedmo;


/**
 * Menu
 *
 * @ORM\Table(name="menu")
 * @ORM\Entity(repositoryClass="AppBundle\Repository\MenuRepository")
 *
 */
class Menu
{
    /**
     * @var int
     *
     * @ORM\Column(name="id", type="integer")
     * @ORM\Id
     * @ORM\GeneratedValue(strategy="AUTO")
     */
    private $id;

    /**
     * @ORM\OneToOne(targetEntity="Coffeeshop")
     * @ORM\JoinColumn(name="coffeeshop_id", referencedColumnName="id")
     */

    private $shopId;

    /**
     * @var \DateTime $updated
     *
     * @Gedmo\Timestampable(on="update")
     * @ORM\Column(type="datetime")
     */

    private $updated;



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

    /**
     * Set shopId
     *
     * @param integer $shopId
     *
     * @return Menu
     */
    public function setShopId($shopId)
    {
        $this->shopId = $shopId;

        return $this;
    }

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

    /**
     * Set lastUpdated
     *
     * @param \DateTime $lastUpdated
     *
     * @return Menu
     */
    public function setLastUpdated($lastUpdated)
    {
        $this->lastUpdated = $lastUpdated;

        return $this;
    }

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

    /**
     * Set updated
     *
     * @param \DateTime $updated
     *
     * @return Menu
     */
    public function setUpdated($updated)
    {
        $this->updated = $updated;

        return $this;
    }

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

咖啡店表单生成器：

<?php
/**

 * Time: 14:20
 */

namespace AppBundle\Form;

use Symfony\Component\Form\AbstractType;
use Symfony\Component\Form\FormBuilderInterface;
use Symfony\Component\Form\Extension\Core\Type\SubmitType;


class CoffeeshopType extends AbstractType
{
    public function buildForm(FormBuilderInterface $builder, array $options)
    {
        $builder
            ->add('name')
            ->add('phone')
            ->add('streetName')
            ->add('houseNumber')
            ->add('zipcode')
            ->add('description')
            ->add('save', SubmitType::class, array('label' => 'Add shop'))
        ;
    }
}

很多方面：

  • 您可以将其定义Coffeeshoptype为服务，然后将 () 注入ManagerRegistry（@doctrine或__construct()仅注入EntityManager），为 event 设置事件侦听器FormEvents::POST_SUBMIT。像这样的东西：

    $this->addEventListener(FormEvents::POST_SUBMIT, function(FormEvent $event) {/*...*/});

  • 在控制器中，您可以在其中持久保存更改Coffeeshoptype

  • 使用 Doctrine 的事件侦听器（或创建实体侦听器，Doctrine 的功能）。通过教条事件，您可以找到实体 ( Coffeeshop) 是否在持续或更新，并根据情况创建新菜单。

以上所有方法都可以访问 Doctrine（感谢依赖注入），其中一些方法也是不好的方法。我建议将 EventListener（或 EventSubscriber）附加到 Doctrine Events 之一，然后坚持新菜单。但是如果你只需要在Coffeeshop通过表单提交时才需要创建新菜单，那么就创建表单类型的事件监听器。
