[英]Naming Strategy for table and column names (Doctrine ORM)
有一種命名策略可以照顧到Doctrine ORM中的表和列名的映射嗎?
現在,所有名稱都是通過實體類中的注釋指定的,例如
<?php
namespace App\Entity;
use DateTimeInterface;
use Doctrine\ORM\Mapping as ORM;
/**
* @ORM\Entity()
* @ORM\Table(name="role")
*/
class Role
{
/**
* @ORM\Id()
* @ORM\Column(name="id", type="guid")
* @ORM\GeneratedValue(strategy="NONE")
* @var string
*/
private $id;
/**
* @ORM\Column(name="created_at", type="datetime")
* @var \DateTimeImmutable
*/
private $createdAt;
/**
* @ORM\Column(name="created_by", type="string")
* @var string
*/
private $createdBy;
// [..]
}
表和列的名稱均為snake_case
而類和屬性的名稱均為camelCase
。
我試圖刪除實體類中的表名和列名聲明,並通過配置提供了命名策略,並嘗試通過以下兩種方式進行設置。
<?php
use Doctrine\ORM\Mapping\UnderscoreNamingStrategy;
return [
'doctrine' => [
'connection' => [
// [..]
],
'driver' => [
// [..]
],
'annotation' => [
// [..]
],
'entity_managers' => [
'default' => [
'naming_strategy' => UnderscoreNamingStrategy::class,
],
],
'orm' => [
'naming_strategy' => UnderscoreNamingStrategy::class,
],
],
];
嘗試檢索實體時,將引發錯誤。
Doctrine\DBAL\Exception\InvalidFieldNameException: An exception occurred while executing 'SELECT t0.id AS id_1, t0.createdAt AS createdAt_2, t0.createdBy AS createdBy_3, t0.updatedAt AS updatedAt_4, t0.updatedBy AS updatedBy_5, t0.name AS name_6, t0.desc AS desc_7, t0.isCore AS isCore_8 FROM Role t0':
SQLSTATE[42S22]: Column not found: 1054 Unknown column 't0.createdAt' in 'field list' in file C:\project\path\vendor\doctrine\dbal\lib\Doctrine\DBAL\Driver\AbstractMySQLDriver.php on line 60
經過一些研究和試驗,我得到了以下解決方案,可以在Zend Expressive應用程序中工作。
在doctrine.local.php中配置命名策略
<?php
declare(strict_types = 1);
use Doctrine\ORM\Mapping\UnderscoreNamingStrategy;
return [
'doctrine' => [
'connection' => [
// [..]
],
'driver' => [
// [..]
],
'annotation' => [
// [..]
],
'configuration' => [
'orm_default' => [
'naming_strategy' => UnderscoreNamingStrategy::class,
],
],
],
];
為命名策略實施工廠
<?php
namespace App;
use Interop\Container\ContainerInterface;
use Zend\ServiceManager\Factory\FactoryInterface;
class NamingStrategyFactory implements FactoryInterface
{
public function __invoke(ContainerInterface $container, $requestedName, array $options = null)
{
return new $requestedName();
}
}
在ConfigProvider.php中注冊工廠
<?php
declare(strict_types = 1);
namespace App;
use Doctrine\ORM\Mapping\UnderscoreNamingStrategy;
class ConfigProvider
{
public function __invoke()
{
return [
'dependencies' => $this->getDependencies(),
];
}
public function getDependencies(): array
{
return [
'invokables' => [
],
'factories' => [
// [..]
UnderscoreNamingStrategy::class => NamingStrategyFactory::class,
],
];
}
}
