在Symfony 2中,我生成了一个Bundle,用于将任何类型的文档存储到数据库中,但我需要BLOB列类型。
Tnx到this question我将类BlobType添加到Doctrine DBAL中,但是要使用新列类型我必须更改
学说\ DBAL \类型\类型
[...]
const BLOB = 'blob';
[...]
private static $_typesMap = array(
[...],
self::BLOB => 'Doctrine\DBAL\Types\BlobType',
);
Doctrine \ DBAL \ Platforms \ MySqlPlatform (如果我更改了Doctrine \ DBAL \ Platforms \ AbstractPlatform,可能会更好)
[...]
protected function initializeDoctrineTypeMappings()
{
$this->doctrineTypeMapping = array(
[...],
'blob' => 'blob',
);
}
[...]
/**
* Obtain DBMS specific SQL to be used to create time fields in statements
* like CREATE TABLE.
*
* @param array $fieldDeclaration
* @return string
*/
public function getBlobTypeDeclarationSQL(array $fieldDeclaration)
{
return 'BLOB';
}
现在我没有'漂亮解决方案'的mouch时间,但是将来我想恢复Doctrine类并能够将新列类型分配到Symfony 2 bootstrap中。 我想我应该编辑我的app / bootstrap.php.cache,但我不知道如何干预。

这对我有用:
创建您的blobtype(请参阅https://gist.github.com/525030/38a0dd6a70e58f39e964ec53c746457dd37a5f58)
将此添加到您的Bundle初始化(/src/YOURDOMAIN/YOURBUNDLE/YOURDOMAINYOUBUNDLE.php)
class YourBundle extends Bundle
{
public function boot()
{
$em = $this->container->get('doctrine.orm.entity_manager');
Type::addType('blob', 'YOURDOMAIN\YOURBUNDLE\YOURTYPEDIRECTORY\BlobType');
$em->getConnection()->getDatabasePlatform()->registerDoctrineTypeMapping('blob','blob');
}
}

XXXBundle :: boot()中的注册 blob 的小改进,但在单元测试期间可能是必要的。
class XXXBundle extends Bundle
{
public function boot()
{
// Add blob type
if(!Type::hasType('blob')) {
Type::addType('blob', '{CLASS_PATH}\\Blob');
}
// Add blob type to current connection.
// Notice: during tests there can be multiple connections to db so
// it will be needed to add 'blob' to all new connections if not defined.
$em = $this->container->get('doctrine.orm.entity_manager');
if (!$em->getConnection()->getDatabasePlatform()->hasDoctrineTypeMappingFor('blob')) {
$em->getConnection()->getDatabasePlatform()->registerDoctrineTypeMapping('blob','blob');
}
}

我刚刚发现了这个要点: https://gist.github.com/525030/38a0dd6a70e58f39e964ec53c746457dd37a5f58
应用程序/ bootstrap.php中:
<?php
// ...
$em = Doctrine\ORM\EntityManager::create($conn, $config, $evm);
// types registration
Doctrine\DBAL\Types\Type::addType('blob', 'Doctrine\DBAL\Types\Blob');
$em->getConnection()->getDatabasePlatform()->registerDoctrineTypeMapping('BLOB', 'blob');
BTW bootstrap.cache.php是自动生成的AFAIK ..所以那里的更改会被覆盖。
