我有实体Basket
和BasketItem
:
/**
* Acme\BasketBundle\Entity\Basket
*
* @ORM\Entity(repositoryClass="Acme\BasketBundle\Repository\BasketRepository")
* @ORM\Table(name="orders")
* @ORM\HasLifecycleCallbacks()
*/
class Basket
{
/**
* @var integer $id
*
* @ORM\Column(name="id", type="integer")
* @ORM\Id
* @ORM\GeneratedValue(strategy="AUTO")
*/
private $id;
// ...
/**
* @ORM\OneToMany(targetEntity="BasketItem", mappedBy="order_id",cascade={"all"})
*/
protected $items;
// ...
public function __construct() {
$this->items = new ArrayCollection();
}
/**
* Add item
*
* @param BasketItem $item
*/
public function addItem(BasketItem $item)
{
$key = $this->find($item->getProduct()->getId());
if ($key === false) {
$this->items->add($item);
} else {
$this->items->get($key)->raiseQuantity($item->getQuantity());
}
}
/**
* Find an item (if present)
*
* @param integer $id
* @return integer
*/
public function find($id)
{
foreach ($this->items as $key => $item) {
if ($item->getProduct()->getId() == $id)
return $key;
}
return false;
}
}
/**
* Acme\BasketBundle\Entity\BasketItem
*
* @ORM\Entity
* @ORM\Table(name="order_items")
*/
class BasketItem
{
/**
* @var integer $id
*
* @ORM\Column(name="id", type="integer")
* @ORM\Id
* @ORM\GeneratedValue(strategy="AUTO")
*/
private $id;
// ...
/**
* @ORM\ManyToOne(targetEntity="Basket", inversedBy="items")
* @ORM\JoinColumn(name="order_id", referencedColumnName="id")
*/
private $basket;
// ...
}
现在,当我创建一个篮子并用项目填充它时,我无法将其持久保存到数据库中。
以下操作无效。
$basket = new Basket();
$basket->addItem(new BasketItem($product1, 1));
$basket->addItem(new BasketItem($product2, 2));
$em->persist($basket);
$em->flush();
然后我尝试更紧密地关注manual:
$basket = new Basket();
$basket->addItem(new BasketItem($product1, 1));
$basket->addItem(new BasketItem($product2, 2));
$em->persist($basket);
foreach ($basket->getItems() as $item) {
$em->persist($item);
}
$em->flush();
这没有按预期工作。
在这两种情况下,所有数据都会保存到数据库但篮子项与篮子无关,即order_id
实体的BasketItem
为{{1 }}
有谁能解释一下我做错了什么,拜托?请注意我是Doctrine的新手。谢谢!
修改:
我真的很困惑。这是我的简化测试:
NULL
<?php

use Doctrine\ORM\Mapping as ORM;
use Doctrine\Common\Collections\ArrayCollection;
/**

class Basket

public function getBasket()
{

}
但仍然 - 订单商品(public function testAction(Request $request) {
$em = $this->getDoctrine()->getEntityManager();
$basket = new Basket();
$basket->addItem(new BasketItem());
$basket->addItem(new BasketItem());
$em->persist($basket);
try {
$em->flush();
} catch(Exception $e) {
die('ERROR: '.$e->getMessage());
}
die ('end');
}
)已存储但未与订单相关联(BasketItem
)。

您的注释映射在您的Basket实体中是错误的:“mappedBy”属性必须引用实体字段,而不是数据库列。
/**
* @ORM\OneToMany(targetEntity="BasketItem", mappedBy="basket",cascade={"all"})
*/
protected $items;
答案 1 :(得分:3)
如果我正确理解了系统,我还必须 - 因为它是双向关系 - 手动将父Basket
实体分配给每个BasketItem
实体。
public function testAction(Request $request) {
$em = $this->getDoctrine()->getEntityManager();
$basket = new Basket();
$bi1 = new BasketItem();
$bi1->setBasket($basket);
$bi2 = new BasketItem();
$bi2->setBasket($basket);
$basket->addItem($bi1);
$basket->addItem($bi2);
$em->persist($basket);
try {
$em->flush();
} catch(Exception $e) {
die('ERROR: '.$e->getMessage());
}
die ('end');
}
这样做很好但是如果我走错路,请纠正我。
感谢所有花时间看我问题的人!

我是Symfony和Doctrine的新人,但这很奇怪。我认为它应该双向工作,但似乎你必须在BasketItem上设置Basket
$bi->setBasket($basket);
如果你想让它以两种方式运作,例如:
$basket->addItem($bi);
你必须修改你的addItem方法和removeItem方法
/**
* Add item
*
* @param BasketItem $item
*/
public function addItem(BasketItem $item)
{
$item->setBasket($this);
$this->items->add($item);
}
/**
* Remove item
*
* @param BasketItem $item
*/
public function removeItem(BasketItem $item)
{
$item->setBasket(null);
$this->items->removeElement($item);
}
