Sammlungsform Symfony nur letzte Artikel gespeichert

Question

Ich versuche ein Formular mit Produkt auf Sylius zu erstellen. Ein Produkt hat ein Attribut "Produkte" (es ist eine Sammlung von Produkten). In meinem Formular verwende ich CollectionType, aber nur das letzte Element wird in der Datenbank gespeichert.

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 
     ]); 
    } 
} 

Ich weiß, dass ein anderes Thema darüber ist, aber die Lösung funktioniert nicht für mich.

Danke für Ihre Zeit.

Answer 1

Dieser Code mein Problem gelöst:

final class PackItemType extends AbstractType 
{ 

    /** 
    * {@inheritdoc} 
    */ 
    public function buildForm(FormBuilderInterface $builder, array $options) 
    { 
     $newPack = new PackItem(); 
     $newPack->setParent($builder->getData()->getParent()); 
     $builder->setData($newPack); 
     $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, 
     ]); 
    } 
}
