Symfony2 协会类形式

Question

这是我的第一个Symfony项目，我不知道如何解决我的问题。

基本上，我正在尝试使用表格制作发票。

我有一个充当关联类的"制造"（即发票）实体、"服务类型"实体和"服务"实体（其唯一属性是发票所需服务类型的数量）。

我想使用 Javascript（可能是 AngularJS）将"新服务"字段动态添加到我的 FacturationType 表单中。因此，我必须创建 N 个新的服务实体，每个实体都与我的 Facturation 实体和现有的 TypeOfService 实体相关联。

这是我的事实实体：

use DoctrineORMMapping AS ORM;
/**
 * Facturation
 *
 * @ORMTable(name="facturation")
 * @ORMEntity
 */
class Facturation
{
    ...

    /**
     * @ORMOneToMany(targetEntity="Service", mappedBy="facturation")
     */
    private $service;
    /**
     * Add service
     *
     * @param AppBundleEntityService $service
     * @return Facturation
     */
    public function addService(AppBundleEntityService $service)
    {
        $this->service[] = $service;
        return $this;
    }
    /**
     * Remove service
     *
     * @param AppBundleEntityService $service
     */
    public function removeService(AppBundleEntityService $service)
    {
        $this->service->removeElement($service);
    }
    /**
     * Get service
     *
     * @return DoctrineCommonCollectionsCollection
     */
    public function getService()
    {
        return $this->service;
    }
}

然后服务：

<?php
namespace AppBundleEntity;
use DoctrineORMMapping AS ORM;
/**
 * Service
 *
 * @ORMTable(name="service")
 * @ORMEntity
 */
class Service
{
    /**
     * @ORMId
     * @ORMColumn(type="integer")
     * @ORMGeneratedValue(strategy="AUTO")
     */
    private $id;
    /**
     * @ORMColumn(type="integer", nullable=true)
     */
    private $quantity;
    /**
     * @ORMManyToOne(targetEntity="TypeOfService", inversedBy="service")
     * @ORMJoinColumn(name="type_of_service_id", referencedColumnName="id")
     */
    private $typeOfService;
    /**
     * @ORMManyToOne(targetEntity="Facturation", inversedBy="service")
     * @ORMJoinColumn(name="facturation_id", referencedColumnName="id")
     */
    private $facturation;
    /**
     * Get id
     *
     * @return integer 
     */
    public function getId()
    {
        return $this->id;
    }
    /**
     * Set quantity
     *
     * @param integer $quantity
     * @return Service
     */
    public function setQuantity($quantity)
    {
        $this->quantity = $quantity;
        return $this;
    }
    /**
     * Get quantity
     *
     * @return integer 
     */
    public function getQuantity()
    {
        return $this->quantity;
    }
    /**
     * Set typeOfService
     *
     * @param AppBundleEntityTypeOfService $typeOfService
     * @return Service
     */
    public function setTypeOfService(AppBundleEntityTypeOfService $typeOfService = null)
    {
        $this->typeOfService = $typeOfService;
        return $this;
    }
    /**
     * Get typeOfService
     *
     * @return AppBundleEntityTypeOfService 
     */
    public function getTypeOfService()
    {
        return $this->typeOfService;
    }
    /**
     * Set facturation
     *
     * @param AppBundleEntityFacturation $facturation
     * @return Service
     */
    public function setFacturation(AppBundleEntityFacturation $facturation = null)
    {
        $this->facturation = $facturation;
        return $this;
    }
    /**
     * Get facturation
     *
     * @return AppBundleEntityFacturation 
     */
    public function getFacturation()
    {
        return $this->facturation;
    }
}

最后是服务类型

<?php
namespace AppBundleEntity;
use DoctrineORMMapping AS ORM;

/**
 * TypeOfService
 *
 * @ORMTable(name="type_of_service")
 * @ORMEntity
 */
class TypeOfService
{
    /**
     * @ORMId
     * @ORMColumn(type="integer")
     * @ORMGeneratedValue(strategy="AUTO")
     */
    private $id;
    /**
     * @ORMColumn(nullable=true)
     */
    private $name;
    /**
     * @ORMColumn(type="integer", nullable=true)
     */
    private $pricePerUnit;
    /**
     * @ORMOneToMany(targetEntity="Service", mappedBy="typeOfService")
     */
    private $service;
    ...
    /**
     * Constructor
     */
    public function __construct()
    {
        $this->service = new DoctrineCommonCollectionsArrayCollection();
    }

    /**
     * Add service
     *
     * @param AppBundleEntityService $service
     * @return TypeOfService
     */
    public function addService(AppBundleEntityService $service)
    {
        $this->service[] = $service;
        return $this;
    }
    /**
     * Remove service
     *
     * @param AppBundleEntityService $service
     */
    public function removeService(AppBundleEntityService $service)
    {
        $this->service->removeElement($service);
    }
    /**
     * Get service
     *
     * @return DoctrineCommonCollectionsCollection
     */
    public function getService()
    {
        return $this->service;
    }
}

谁能指出我正确的方向？

Answer 1

对于任何看的人来说，我已经破解了它。

这就是我正在寻找的：

http://symfony.com/doc/current/cookbook/form/form_collections.html

这允许使用 JS 进行动态字段添加。请注意级联您的关联。就我而言：

class Facturation
{
....
    /**
     * @ORMOneToMany(targetEntity="Service", mappedBy="facturation", cascade={"persist", "remove"})
     */
    private $services;
