我正在嘗試在Sylius上創建一個帶有產品的表單。產品具有屬性「產品」（這是產品的集合）。因此，在我的表單中，我使用了CollectionType，但只有最後一項保存在數據庫中。收藏表格Symfony only last保存
Product.php
/**
* @ORM\Entity
* @ORM\Table(name="sylius_product")
*/
class Product extends BaseProduct
{
/**
* @ORM\OneToMany(targetEntity="XXX\PackBundle\Entity\PackItem", mappedBy="parent", cascade={"persist"})
* @var PackItem[]|ArrayCollection $products
*/
private $products;
/**
* @ORM\Column(type="integer", nullable=true)
*/
private $area;
/**
* @ORM\Column(type="integer")
*/
private $lifetime;
public function __construct($lifetime=1)
{
parent::__construct();
$this->products = new ArrayCollection();
$this->lifetime = $lifetime;
}
/**
* @return PackItem[]|ArrayCollection
*/
public function getProducts() {
return $this->products;
}
/**
* @param PackItem $product
*/
public function addProduct(PackItem $product) {
$product->setParent($this);
$this->products->add($product);
return $this;
}
/**
* @param ArrayCollection|PackItem[] $products
*/
public function setProducts($products)
{
$this->products = $products;
}
/**
* @return True if the product is a pack
*/
public function isPack() {
return !($this->products->isEmpty());
}
}
PackItem.php
/**
* @ORM\Entity
* @ORM\Table(name="pack_product")
*/
class PackItem
{
/**
* @ORM\Id
* @ORM\ManyToOne(targetEntity="XXXX\PackBundle\Entity\Product")
* @ORM\JoinColumn(name="parent_id", referencedColumnName="id", onDelete="CASCADE")
*/
private $parent;
/**
* @ORM\Id
* @ORM\ManyToOne(targetEntity="XXXX\PackBundle\Entity\Product")
* @ORM\JoinColumn(name="child_id", referencedColumnName="id", onDelete="CASCADE")
*/
private $child;
/**
* @ORM\Column(name="quantity", type="integer")
*/
private $quantity;
/**
* @return Product
*/
public function getParent()
{
return $this->parent;
}
/**
* @param Product $parent
*/
public function setParent($parent)
{
$this->parent = $parent;
return $this;
}
/**
* @return Product
*/
public function getChild()
{
return $this->child;
}
/**
* @param Product $child
*/
public function setChild($child)
{
$this->child = $child;
return $this;
}
/**
* @return int
*/
public function getQuantity()
{
return $this->quantity;
}
/**
* @param int $quantity
*/
public function setQuantity($quantity)
{
$this->quantity = $quantity;
}
}
ProductTypeExtension.php
final class ProductTypeExtension extends AbstractTypeExtension
{
/**
* {@inheritdoc}
*/
public function buildForm(FormBuilderInterface $builder, array $options)
{
/** @var PackItem $packItem */
$packItem = new PackItem();
$packItem->setParent($builder->getData());
$builder
->add('products', CollectionType::class, [
'entry_type' => PackItemType::class,
'allow_add' => true,
'allow_delete' => true,
'entry_options' => [
'data' => $packItem
],
'by_reference' => false,
]);
}
/**
* {@inheritdoc}
*/
public function getExtendedType()
{
return ProductType::class;
}
}
PackItemType.php
#PackItemType.php
final class PackItemType extends AbstractType
{
/**
* {@inheritdoc}
*/
public function buildForm(FormBuilderInterface $builder, array $options)
{
$builder
->add('child', 'entity', [
'label' => 'XXXX.ui.token',
'class' => Product::class,
'query_builder' => function(EntityRepository $er) {
$qr = $er->createQueryBuilder('t')
->leftJoin('t.products', 'p')
->having('COUNT(p.parent) = 0')
->groupBy('t.id')
->orderBy('t.code', 'ASC')
;
return $qr;
}
])
->add('quantity', IntegerType::class)
;
}
public function configureOptions(OptionsResolver $resolver)
{
$resolver->setDefaults([
'data_class' => PackItem::class
]);
}
}
我知道另外一個主題就是這個，但是這個解決方案對我來說並不合適。
謝謝你的時間。
