【问题描述】：

我在 Symfony4 和 Sonata Admin 中遇到问题。

我有 3 个实体：订单、产品和订单产品。 他们在这里：

订单：

class Orders

    /**
     * @ORM\Id()
     * @ORM\GeneratedValue()
     * @ORM\Column(type="integer")
     */
    private $id;

    /**
     * @ORM\Column(type="datetime")
     */
    private $dateAdd;

    /**
     * @ORM\Column(type="datetime")
     */
    private $dateUpd;

    /**
     * @ORM\Column(type="date")
     */
    private $deliveryDate;

    /**
     * @ORM\Column(type="string", length=255)
     */
    private $internalReference;

    /**
     * @ORM\Column(type="string", length=255)
     */
    private $deliveryContactName;

    /**
     * @ORM\Column(type="string", length=15)
     */
    private $deliveryContactPhone;

    /**
     * @ORM\Column(type="string", length=255)
     */
    private $deliveryAddress1;

    /**
     * @ORM\Column(type="string", length=255, nullable=true)
     */
    private $deliveryAddress2;

    /**

产品：

class Product

        return $this->isDeleted;
    

    public function setIsDeleted(bool $isDeleted): self
    
        $this->isDeleted = $isDeleted;

        return $this;
    

    public function __toString()
    
        if ($this->name)
            return $this->name;
        else
            return "Nouveau Produit";
    

    public function calculatePriceTI()
    
        return $this->priceWT * (1 + $this->vat);
    

订单产品：

class OrdersProduct

    /**
     * @ORM\Id()
     * @ORM\GeneratedValue()
     * @ORM\Column(type="integer")
     */
    private $id;

    /**

     */
    private $orders;

    /**
     * @ORM\ManyToOne(targetEntity="App\Entity\Product")
     * @ORM\JoinColumn(nullable=false)
     */
    private $product;

    /**
     * @ORM\Column(type="integer")
     */
    private $quantity;

    /**
     * @ORM\Column(type="float")
     */
    private $priceWT;

    public function getId(): ?int
    
        return $this->id;
    

    public function getOrders(): ?Orders
    
        return $this->orders;
    

    public function setOrders(?Orders $orders): self
    
        $this->orders = $orders;

        return $this;
    

    public function getProduct(): ?Product
    
        return $this->product;
    

    public function setProduct(?Product $product): self
    
        $this->product = $product;

        return $this;
    

    public function getQuantity(): ?int
    
        return $this->quantity;
    

    public function setQuantity(int $quantity): self
    
        $this->quantity = $quantity;

        return $this;
    

    public function getPriceWT(): ?float
    
        return $this->priceWT;
    

    public function setPriceWT(float $priceWT): self
    
        $this->priceWT = $priceWT;

        return $this;
    

    public function __toString()
    
        if($this->id)
            return $this->getOrders()->getId()." - ".$this->getProduct()->getName();
        else
            return "";
    

这里是订单管理员：

class OrdersAdmin extends AbstractAdmin

    protected function configureFormFields(FormMapper $formMapper)
    
        $formMapper->with('label.orders.group1', [
            'class' => 'col-md-6'
        ])
            ->add('internalReference', TextType::class, [
                'label' => 'label.orders.internalReference',
                'required' => true
        ])
            ->add('deliveryDate', DateType::class, [
                'label' => 'label.orders.deliveryDate'
            ])
            ->add('comment', TextareaType::class, [
                'label' => 'label.orders.comment',
                'required' => false
            ])
            ->add('deliveryContactName', TextType::class, [
                'label' => 'label.orders.deliveryContactName'
            ])
            ->add('deliveryContactPhone', TextType::class, [
                'label' => 'label.orders.deliveryContactPhone'
            ])
            ->add('status', ChoiceType::class, [
                'label' => 'label.orders.status',
                'choices' => array(
                    'label.orders.statuses.pending' => 1,
                    'label.orders.statuses.confirmed' => 2,
                    'label.orders.statuses.sent' => 3,
                    'label.orders.statuses.cancel' => 4,
                )
            ])
            ->end();
        $formMapper->with('label.orders.group2', [
            'class' => 'col-md-6'
        ])
            ->add('deliveryCompany', TextType::class, [
                'label' => 'label.orders.deliveryCompany',
                'required' => false
            ])
            ->add('deliveryAddress1', TextType::class, [
                'label' => 'label.orders.deliveryAddress1'
            ])
            ->add('deliveryAddress2', TextType::class, [
                'label' => 'label.orders.deliveryAddress2',
                'required' => false
            ])
            ->add('deliveryPostalCode', TextType::class, [
                'label' => 'label.orders.deliveryPostalCode'
            ])
            ->add('deliveryCity', TextType::class, [
                'label' => 'label.orders.deliveryCity'
            ])
            ->add('deliveryCountry', TextType::class, [
                'label' => 'label.orders.deliveryCountry'
            ])
            ->end();

        if ($this->isCurrentRoute('edit', 'admin.orders'))
            $formMapper->add('product', OrdersProductType::class, array(
                'order' => $this->getSubject(),
            )
            );

    

    protected function configureDatagridFilters(DatagridMapper $filter)
    
        $filter->add('internalReference')
            ->add('deliveryCompany');
    

    protected function configureListFields(ListMapper $list)
    
        $list->addIdentifier('id');
        $list->add('dateAdd', 'date', [
            'label' => 'label.orders.dateAdd'
        ]);
    

    public function prePersist($orders)
    
        $orders->setdateAdd(new \DateTime());
        $orders->setDateUpd(new \DateTime());

    

    public function preUpdate($orders)
    
        $orders->setDateUpd(new \DateTime());
    

还有 OrdersProductType ：

class OrdersProductType extends AbstractType


    public function buildForm(FormBuilderInterface $builder, array $options)
    

        $builder->add('product', EntityType::class, array(
            'class' => Product::class,
            'multiple' => false,
            'expanded' => false,
        ))
            ->add('quantity')
            ->add('priceWT')
            ->add('orders', HiddenType::class, array(
                'data' => $options['order']
            ));
    

    public function configureOptions(OptionsResolver $resolver)
    
        $resolver->setRequired(array('order'));
    

我尝试将 CollectionType::class 与 OrdersProductAdmin 一起使用，但无法保存 OrdersProduct，因为我不知道如何将 Orders id 传递给嵌入式表单。所以，我做了一个自定义表单类型，但是：

当我提交表单时，我收到错误：

Expected value of type "App\Entity\OrdersProduct" for association field "App\Entity\Orders#$product", got "Proxies\__CG__\App\Entity\Product" instead.

如果我在 preupdate 函数中转储 $orders 变量，我有：

OrdersAdmin.php on line 121:
OrdersProduct #1405 ▶
OrdersAdmin.php on line 121:
OrdersProduct #1419 ▶
OrdersAdmin.php on line 121:
Product #1420 ▶
OrdersAdmin.php on line 121:
"33"
OrdersAdmin.php on line 121:
"12"
OrdersAdmin.php on line 121:
"1 -SG-000251 wonder"

前 2 个 OrdersProduct 是正确的（它们在我的数据库中）。但是最后 4 项是不正确的！它应该是 OrdersProduct，带有产品、数量、价格和订单。

感谢您的帮助。

最好的

【参考方案1】：

我找到了（部分，因为我现在有一个表单问题！）解决方案！

代码如下：

订单类：
