名称已存在的表

Question

我正在尝试解决此问题

执行时

php bin/console doctrine:schema:update --dump-sql

我正在

In SchemaException.php line 108:
The table with name 'chris_test_sonata.page__block' already exists.

显然，该表在我的数据库中不存在。为确保它与缓存​​无关，我什至对刚创建的新数据库进行了操作，结果是相同的。

当我在项目中搜索page__block时，我只会找到此映射

/**
 * @ORM\Entity
 * @ORM\Table(name="page__block")
 * @ORM\HasLifecycleCallbacks
 */
class SonataPageBlock extends BaseBlock

因此该表不应有其他映射。

我也有一个block.orm.xml

<?xml version="1.0" encoding="utf-8"?>
<doctrine-mapping xmlns="http://doctrine-project.org/schemas/orm/doctrine-mapping" xsi="http://www.w3.org/2001/XMLSchema-instance" schemaLocation="http://doctrine-project.org/schemas/orm/doctrine-mapping http://doctrine-project.org/schemas/orm/doctrine-mapping.xsd">

    -->
    <entity
        name="App\Application\Sonata\PageBundle\Entity\Block"
        table="page__block"
        repository-class="Doctrine\ORM\EntityRepository">

        <id name="id" type="integer" column="id">
            <generator strategy="AUTO"/>
        </id>

    </entity>
</doctrine-mapping>

还有其他一些情况，但都在dev.log中

而且我在symfony dev / pools的缓存文件中也有此文件

<?php

namespace Symfony\Component\VarExporter\Internal;

return $getExpiry ? PHP_INT_MAX : Hydrator::hydrate(
    $o = [
        clone (($p = &Registry::$prototypes)['Doctrine\\ORM\\Mapping\\Entity'] ?? Registry::p('Doctrine\\ORM\\Mapping\\Entity')),
        clone ($p['Doctrine\\ORM\\Mapping\\Table'] ?? Registry::p('Doctrine\\ORM\\Mapping\\Table')),
        clone ($p['Doctrine\\ORM\\Mapping\\HasLifecycleCallbacks'] ?? Registry::p('Doctrine\\ORM\\Mapping\\HasLifecycleCallbacks')),
    ],
    null,
    [
        'stdClass' => [
            'name' => [
                1 => 'page__block',
            ],
        ],
    ],
    [
        $o[0],
        $o[1],
        $o[2],
    ],
    []
);

我不知道它有什么问题以及为什么映射不起作用。

问题是，您具有带有表Block的page__block实体，并且创建了具有相同表名的新实体SonataPageBlock。如果更改SonataPageBlock的表名，一切都很好，但是它将是数据库中的2个不同的表。
