Question

我正在尝试使用产品构建器创建Sylius产品。当我尝试构建产品时，出现以下错误：

Found entity of type Sylius\Bundle\CoreBundle\Model\Variant on association
Shopfish\Bundle\CoreBundle\Entity\Product#variants, but expecting
Shopfish\Bundle\CoreBundle\Entity\Variant

我正在尝试使用以下代码段构建产品：

/**
 * @Route("/admin/products/create", name="sf_product_create")
 * @Template()
 */
public function createAction(Request $request)
{
    $product = $this->get('sylius.builder.product')
        ->create('My Lovely Product')
        ->setPrice(18790)
        ->setDescription('Such a lovely product.')
        ->addProperty('color', 'Red')
        ->save()
    ;

    return array('product' => $product);
}

我已经覆盖了SyliusProduct：

use Sylius\Bundle\CoreBundle\Model\Product as BaseProduct;

class Product extends BaseProduct
{
    protected $resource; // going to do something with this later on.
}

SyliusVariant以类似的方式被覆盖：

use Sylius\Bundle\CoreBundle\Model\Variant as BaseVariant;

class Variant extends BaseVariant {
    protected $salePrice;

    // ... + getSalePrice() & setSalePrice()
}

我已更新sylius.yml中的配置文件以使用我自己的类：

sylius_product:
    classes:
        product:
            model: Shopfish\Bundle\CoreBundle\Entity\Product
            controller: Sylius\Bundle\CoreBundle\Controller\ProductController
            repository: Sylius\Bundle\CoreBundle\Repository\ProductRepository
            form: Sylius\Bundle\CoreBundle\Form\Type\ProductType

sylius_variable_product:
    classes:
        variant:
            model: Shopfish\Bundle\CoreBundle\Entity\Variant
            repository: Sylius\Bundle\CoreBundle\Repository\VariantRepository
            form: Sylius\Bundle\CoreBundle\Form\Type\VariantType

为什么它使用Sylius变体进行关联，而它正确地期望我自己Variant的实例？

修改

这是我的产品映射：

<doctrine-mapping xmlns="http://doctrine-project.org/schemas/orm/doctrine-mapping"
                  xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
                  xsi:schemaLocation="http://doctrine-project.org/schemas/orm/doctrine-mapping
                                      http://doctrine-project.org/schemas/orm/doctrine-mapping.xsd">

    <entity name="Shopfish\Bundle\CoreBundle\Entity\Product" table="sylius_product">
        <one-to-many field="variants" target-entity="Shopfish\Bundle\CoreBundle\Entity\Variant" mapped-by="product">
            <cascade>
                <cascade-all />
            </cascade>
        </one-to-many>
    </entity>

</doctrine-mapping>

Answer 1

我认为这是一个小错误，但您可以通过覆盖自己的Product类中的构造函数轻松解决它。

CoreBundle \型号\产品：

public function __construct()
{
    parent::__construct();

    $this->setMasterVariant(new Variant());
    $this->taxons = new ArrayCollection();

    $this->variantSelectionMethod = self::VARIANT_SELECTION_CHOICE;
}

Master Variant设置为CoreBundle \ Model \ Variant的实例。在您自己的产品模型中覆盖构造函数：

public function __construct()
{
    parent::__construct();

    $this->setMasterVariant(new YourCustomVariant());
}

这可能应该修复：）。

Answer 2

要关注最新的sylius dev，您需要扩展Products模型，并将__construct替换为以下代码

public function __construct()
{
    parent::__construct();

    $this
        ->setVariants(new ArrayCollection())
        ->setMasterVariant(new YourCustomVariant())
    ;
}

Sylius - 产品生成器未使用预期的实体（覆盖）
