奏鸣曲捆绑发行[产品捆绑]

Question

I'm trying to set Sonata Bundles Ecommerce on Symfony 2.3.

I followed install steps mentionned here but I'm getting an error when trying to load my page requesting app_dev.php.

Here is the error

FatalErrorException: Compile Error: Declaration of Sonata\\ProductBundle\\Entity\\BaseProduct::validateOneMainCategory() must be compatible with Sonata\\Component\\Product\\ProductInterface::validateOneMainCategory(Symfony\\Component\\Validator\\Context\\LegacyExecutionContext $context) in /xxx/xx/xx/xxxx/vendor/sonata-project/ecommerce/src/ProductBundle/Entity/BaseProduct.php line 28

Can anyone help me to solve this ?

Answer 1

我在使用Sonata管理员捆绑包之前收到了此错误消息，我认为您应该注意文件顶部的uses语句。您需要添加适当的use语句。在ProductInterface上查找您将找到要使用的正确文件。

I have this in ProductInterface

    use Symfony\Component\Validator\Context\LegacyExecutionContext;

/**
     * Validates if product has one main category
     *
     * @param LegacyExecutionContext $context
     *
     * @return void
     */
    public function validateOneMainCategory(LegacyExecutionContext $context);

And in BaseProduct.php

use Symfony\Component\Validator\ExecutionContext;

   /**
     * {@inheritdoc}
     */
    public function validateOneMainCategory(LegacyExecutionContext $context)
    {
        if ($this->getCategories()->count() == 0) {
            return;
        }

        if (!$this->hasOneMainCategory()) {
            $context->addViolation('sonata.product.must_have_one_main_category');
        }
    }
