Symfony Easy Admin Bundle：预加载嵌套表单数据 - 类型实体失败......必须管理

Question

我正在尝试为这三个实例创建一个嵌套表单，其中库存有默认数据，嵌套表单InventoryProduct在表单中默认包含数据库中的所有产品。

Inventory（有一个或多个InventarioProduct）- Id, StartDate, EndDate
InventoryProduct - Id, Product, Units, RejectedUnits, QuarantineUnits
Product - Id、Name、Inci、产品的一些其他数据

所以我们将 InventoryCrudCrontroller 添加到 createEntityMethod:

public function createEntity(string $entityFqcn)
    {
        $inventory= new Inventory();
        $inventory->setStartDate(new DateTime('now'));
        $inventory->setEndDate(null);

        $productRepository= $this->entityManager->getRepository(MateriaPrima::class);

        $products= $productRepository->findAll();

        foreach ($products as $product) {
            $inventoryProduct= new InventoryProduct();
            $inventoryProduct->setProduct($product);
            $inventoryProduct->setUnits(0);
            $inventoryProduct->setUnitsRejected(0);
            $inventoryProduct->setUnitsQuarantine(0);
            $inventoryProduct->setInventory($inventory);

            $inventory->addInventarioProduct($inventoryProduct);
        }

以及 InventoryCrudCrontroller 上的 configureFields 方法：

public function configureFields(string $pageName): iterable
    {

        if (Crud::PAGE_EDIT === $pageName || Crud::PAGE_NEW == $pageName) {
            return [
                DateTimeField::new('startDate')
                    ->setColumns(6)
                    ->setValue(new DateTime()),
                DateTimeField::new('endDate')
                    ->setColumns(6),
                CollectionField::new('products', 'Products:')
                    ->onlyOnForms()
                    ->allowAdd()
                    ->allowDelete()
                    ->setEntryIsComplex(false)
                    ->setEntryType(InventoryProductType::class)
                    ->renderExpanded(true)
                    ->setFormTypeOptions(
                        [
                            'by_reference' => false,
                        ]
                    )
                    ->setColumns(12),

然后我们为海关表格添加 class InventoryProductType：

class InventoryProducts extends AbstractType
{
    public function buildForm(FormBuilderInterface $builder, array $options): void
    {

        $builder
            ->add(
                'product',
                EntityType::class,
                ['class' => Product::class, 'label' => '-']
            )
            ->add('units')
            ->add('unitsRejected')
            ->add('unitsQuarantine')
            ;
    }

    public function configureOptions(OptionsResolver $resolver): void
    {
        $resolver->setDefaults([
            'data_class' => InventoryProduct::class,
        ]);
    }
}

当我们尝试添加另一个注册表时，我们得到：

Entity of type "App\Entity\Inventory" passed to the choice field must be managed. Maybe you forget to persist it in the entity manager?

我做错了什么？

感谢您的帮助！！

Answer 1

该错误告诉您您正在使用类型为 App\Entity\Inventory 的实体，该实体不受实体管理器管理。

如果您查看您的代码，您会在 createEntity 方法中创建一个新实体，但从未持久化它。

您可以将其坚持在您的方法中，例如：

public function createEntity(string $entityFqcn)
    {
        $inventory= new Inventory();
        $inventory->setStartDate(new DateTime('now'));
        $inventory->setEndDate(null);
        $this->entityManager->persist($inventory);

        $productRepository= $this->entityManager->getRepository(MateriaPrima::class);

        $products= $productRepository->findAll();
        
        foreach ($products as $product) {
            $inventoryProduct= new InventoryProduct();
            $inventoryProduct->setProduct($product);
            $inventoryProduct->setUnits(0);
            $inventoryProduct->setUnitsRejected(0);
            $inventoryProduct->setUnitsQuarantine(0);
            $inventoryProduct->setInventory($inventory);
            $this->entityManager->persist($inventoryProduct);

            $inventory->addInventarioProduct($inventoryProduct);
        }
    }

Or add cascading persist on your entity.
