Question

我已经在我的symfony 2应用程序中安装了sylius cart-bundle。

当我尝试在购物车中放入产品时，我有以下例外：

FatalErrorException：编译错误：Lyckee \ StoreBundle \ Cart \ ItemResolver :: resolve（）声明必须与Sylius \ Bundle \ CartBundle \ Resolver \ ItemResolverInterface :: resolve兼容（Sylius \ Bundle \ CartBundle \ Model \ CartItemInterface $ item ，$ data）/Applications/MAMP/htdocs/Symfony/src/Lyckee/StoreBundle/Cart/ItemResolver.php第13行

我发现有人在这里遇到与我相同的问题：Sylius CartBundle Symfony2

他在service.yml文件中遇到问题解决了这个问题，但它对我不起作用。

我的CartItem类：

namespace Lyckee\StoreBundle\Entity;

use Sylius\Bundle\CartBundle\Model\CartItem as BaseCartItem;
use Doctrine\ORM\Mapping as ORM;
/**
 * @ORM\Table()
 * @ORM\Entity
 * @ORM\Table(name="lyckee_cart_item_1")
 */
class CartItem extends BaseCartItem
{
    /**
     *@ORM\ManyToOne(targetEntity="Lyckee\StoreBundle\Entity\Product")
     * @ORM\JoinColumn(nullable=false))
     */
    private $product;

    /**
     * Get product
     *
     * @return \Lyckee\StoreBundle\Entity\Product
     */
    public function getProduct()
    {
        return $this->product;
    }
    /**
     * Set product
     *
     * @param \Lyckee\StoreBundle\Entity\Product $product
     * @return CartItem
     */

    public function setProduct(\Lyckee\StoreBundle\Entity\Product $product)
    {
        $this->product = $product;
    }}

我的物品解析器

namespace Lyckee\StoreBundle\Cart;

use Sylius\Bundle\CartBundle\Model\CartItemInterface;
use Sylius\Bundle\CartBundle\Resolver\ItemResolverInterface;
use Sylius\Bundle\CartBundle\Resolver\ItemResolvingException;
use Symfony\Component\HttpFoundation\Request;
use Doctrine\ORM\EntityManager;

class ItemResolver implements ItemResolverInterface
{
    private $entityManager;

    public function __construct(EntityManager $entityManager)
    {
        $this->entityManager = $entityManager;
    }

    public function resolve(CartItemInterface $item, Request $request)
    {
        //$productId = $request->query->get('productId');

        // If no product id given, or product not found, we throw exception with nice message.
        if (!$productId || !$product = $this->getProductRepository()->find($productId)) {
            throw new ItemResolvingException('Requested product was not found');
        }

        // Assign the product to the item and define the unit price.
        $item->setProduct($product);
        $item->setUnitPrice($product->getPrix());

        // Everything went fine, return the item.
        return $item;
    }

    private function getProductRepository()
    {
        return $this->entityManager->getRepository('LyckeeStoreBundle:Product');
    }
}

Answer 1

由于您调用resolve方法时出现此错误

 public function resolve(CartItemInterface $item, Request $request)

那时你必须传递第一个参数$item，它必须是CartItem类的实例。

请查看文档，了解有关Cart Provider＆amp; amp ;;的详细信息。解析器。

Answer 2

需要更新文档，您只需要删除＆＃34;请求＆＃34; ：

public function resolve(CartItemInterface $item, $request)

sylius cart-bundle - FattalErrorException：ItemResolver :: resolve（）必须兼容
