我尝试覆盖categoryakeneo 项目的实体。我遵循文档，但总是有一个我无法解决的错误。

添加了这个config.yml

-
    original: Pim\Bundle\CatalogBundle\Entity\Category
    override: MyBundle\CatalogBundle\Entity\Category

在entities.yml

parameters:
    pim_catalog.entity.category.class: MyBundle\CatalogBundle\Entity\Category

覆盖，category.php

<?php

namespace MyBundle\CatalogBundle\Entity;

use Pim\Bundle\CatalogBundle\Entity\Category as BaseCategory;

class Category extends BaseCategory
{
    protected $test;

    public function getTest()
    {
        return $this->test;
    }

    public function setTest($test)
    {
        $this->test = $test;

        return $this;
    }
}

category.orm.yml

MyBundle\CatalogBundle\Entity\Category:
    type: entity
    table: pim_catalog_category
    changeTrackingPolicy: DEFERRED_EXPLICIT
    repositoryClass: Akeneo\Bundle\ClassificationBundle\Doctrine\ORM\Repository\CategoryRepository
    uniqueConstraints:
        pim_category_code_uc:
            columns:
                - code
    gedmo:
        tree:
            type: nested
    fields:
        test:
            type: string
            length: 255
            nullable: true

然后在浏览器上出现以下错误：

UnexpectedValueException in TreeListener.php line 74: Tree object class: Pim\Bundle\CatalogBundle\Entity\Category must have tree metadata at this point

这是抛出异常的函数，它是 gedmo 学说扩展的一部分

 public function getStrategy(ObjectManager $om, $class)
{
    if (!isset($this->strategies[$class])) {
        $config = $this->getConfiguration($om, $class);

        if (!$config) {
            throw new \Gedmo\Exception\UnexpectedValueException("Tree object class: {$class} must have tree metadata at this point");
        }
        $managerName = 'UnsupportedManager';
        if ($om instanceof \Doctrine\ORM\EntityManager) {
            $managerName = 'ORM';
        } elseif ($om instanceof \Doctrine\ODM\MongoDB\DocumentManager) {
            $managerName = 'ODM\\MongoDB';
        }
        if (!isset($this->strategyInstances[$config['strategy']])) {
            $strategyClass = $this->getNamespace().'\\Strategy\\'.$managerName.'\\'.ucfirst($config['strategy']);

            if (!class_exists($strategyClass)) {
                throw new \Gedmo\Exception\InvalidArgumentException($managerName." TreeListener does not support tree type: {$config['strategy']}");
            }
            $this->strategyInstances[$config['strategy']] = new $strategyClass($this);
        }
        $this->strategies[$class] = $config['strategy'];
    }

    return $this->strategyInstances[$this->strategies[$class]];
}

解决方案：

上述问题是由于 DependencyInjection 而发生的。为了解决此问题，请按照以下说明操作：

创建扩展类：

1) It has to live in the DependencyInjection namespace of the bundle;
2) It has to implement the ExtensionInterface, which is usually achieved by extending the Extension class;
3) The name is equal to the bundle name with the Bundle suffix replaced by Extension (e.g. the Extension class of the AcmeBundle would be called AcmeExtension and the one for AcmeCatalogBundle would be called AcmeCatalogExtension).

# /src/Acme/Bundle/CatalogBu​​ndle/DependencyInjection/AcmeCatalogExtension.php 

<?php

namespace Acme\Bundle\CatalogBundle\DependencyInjection;

use Symfony\Component\Config\FileLocator;
use Symfony\Component\DependencyInjection\ContainerBuilder;
use Symfony\Component\DependencyInjection\Loader;
use Symfony\Component\HttpKernel\DependencyInjection\Extension;

class AcmeCatalogExtension extends Extension
{
    public function load(array $configs, ContainerBuilder $container)
    {
        $loader = new Loader\YamlFileLoader($container, new FileLocator(__DIR__.'/../Resources/config'));
        $loader->load('entities.yml');
    }
}

如果您有任何问题，请告诉我

确保您正在加载父级。

在文件 /src/Acme/Bundle/CatalogBu​​ndle/AcmeCatalogBu​​ndle.php 添加

public function getParent()
{
    return 'PimCatalogBundle';
}
