symfony - Sonata Admin => 仅选择给定的鉴别器映射类型

Question

主题

当我有一组带有 Doctrine Discriminator Map 的实体时，由于 SonataAdminBundle 和/或 SonataDoctrineORMAdminBundle，我无法添加过滤器来获取所有映射实体中的一种类型> 正在抛出错误。

示例:

具有 Doctrine 鉴别器映射的实体

/**
 * @ORM\Table(name="activities")
 * @ORM\Entity()
 * @ORM\InheritanceType("SINGLE_TABLE")
 * @ORM\DiscriminatorColumn(name="type", type="string")
 * @ORM\DiscriminatorMap({
 *     "joined" = "...\JoinedActivity",
 *     "other" = "...\OtherActivity"
 * })
 */
abstract class Activity()
{
    abstract public function getType();
}

/**
 * @ORM\Entity()
 */
class JoinActivity extends Activity()
{
    const TYPE = 'joined';

    public function getType()
    {
        return self::type;
    }
}

/**
 * @ORM\Entity()
 */
class OtherActivity extends Activity()
{
    const TYPE = 'other';

    public function getType()
    {
        return self::type;
    }
}

然后我添加 Sonata Admin 过滤器:

protected function configureDatagridFilters(DatagridMapper $filter)
{
    $filter->add(
        'type',
        null,
        [
            'label' => 'Activity Type',
        ],
        'choice',
        [
            'choices' => [
                JoinActivity::TYPE => ucfirst(JoinActivity::TYPE),
                OtherActivity::TYPE => ucfirst(OtherActivity::TYPE),
            ],
        ]
    );
}

预期结果

获取一个新过滤器以选择仅加入 或其他 事件。

实际结果

Notice: Undefined index: type
500 Internal Server Error - ContextErrorException

堆栈跟踪

根据 greg0ire 的要求，这是 Symfony/Sonata 返回的堆栈跟踪:

知道如何修复它吗？

谢谢，

我遇到了同样的问题。我做了一个变通 - 我使用 doctrine_orm_callback 类型和 doctrine INSTANCE OF 运算符。

代码如下所示:

->add('userType',
            'doctrine_orm_callback',
            [
                'callback' => function ($queryBuilder, $alias, $field, $value) {
                    if (!is_array($value) || !array_key_exists('value', $value) || empty($value['value'])) {
                        return false;
                    }

                    $queryBuilder->andWhere($alias . ' INSTANCE OF :userType');
                    $queryBuilder->setParameter('userType', $value['value']);

                    return true;
                },
            ],
            ChoiceType::class,
            [
                'choices' => array_flip(UserType::getChoices()),
                'translation_domain' => $this->getTranslationDomain(),
            ]
        )

它正在运行。也许对您有帮助。
