Magento 2:覆盖Magento\Review\Block\Product无效

Question

我试图覆盖Magento 2中的产品视图评审块，但我无法让它工作。

app/code/Package/CombineReviews/etc/module.xml

<?php

    public function getReviewsSummaryHtml(

        $templateType = false,

    ) {
        return $this->getLayout()->createBlock(
            'Magento\Review\Block\Rating\Entity\Detailed'
        )->setEntityId(
            $this->getProduct()->getId()
        )->toHtml() . $this->getLayout()->getBlock(
            'product_review_list.count'
        )->assign(
            'count',
            $this->getReviewsCollection()->getSize()
        )->toHtml();
    }

    /**
     * Get collection of reviews
     *
     * @return ReviewCollection
     */
    public function getReviewsCollection()
    {
        if (null === $this->_reviewsCollection) {
            $this->_reviewsCollection = $this->_reviewsColFactory->create()->addStoreFilter(
                $this->_storeManager->getStore()->getId()
            )->addStatusFilter(
                \Magento\Review\Model\Review::STATUS_APPROVED
            )->addEntityFilter(
                'product',
                3
                //$this->getProduct()->getId()
            )->setDateOrder();
        }
        return $this->_reviewsCollection;
    }

    /**
     * Force product view page behave like without options
     *
     * @return bool
     */
    public function hasOptions()
    {
        return false;
    }
    }

在函数ReviewCollection中，我做了一个小修改：

)->addEntityFilter(
    'product',
    3
    //$this->getProduct()->getId()

这种修改是从核心文件中进行的，但在我的自定义模块中不起作用。我也试图从这个函数返回'test‘，但是我无法让它工作。

有人看到问题了吗？

您应该使用以下代码修改您的app/code/[Package]/CombineReviews/etc/module.xml。

<?xml version="1.0"?>
<config xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="../../../../../lib/internal/Magento/Framework/Module/etc/module.xsd">
    <module name="[Package]_CombineReviews" setup_version="1.0.0" schema_version="1.0.0">
        <sequence>
            <module name="Magento_Review" />
        </sequence>
    </module>
</config>

将文件路径从app/code/Package/CombineReviews/Block/Magento/Review/Product/View.php更改为app/code/Package/CombineReviews/Block/Product/View.php.

运行setup: upgrade和static-content: deploy命令并检查。希望这样能行。
