[英]How add BLOB type in Doctrine 2 using Symfony 2
In Symfony 2 I generate a Bundle for storing any type of document into database, but I need the BLOB column type. 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,但是我需要BLOB列类型。
Tnx to this question I add the class BlobType into Doctrine DBAL, but for use the new column type I had to change 在这个问题上,我将类BlobType添加到Doctrine DBAL中,但是要使用新的列类型,我必须进行更改
Doctrine\\DBAL\\Types\\Type 原则\\ DBAL \\类型\\类型
[...]
const BLOB = 'blob';
[...]
private static $_typesMap = array(
[...],
self::BLOB => 'Doctrine\DBAL\Types\BlobType',
);
Doctrine\\DBAL\\Platforms\\MySqlPlatform (maybe it was better if I had changed Doctrine\\DBAL\\Platforms\\AbstractPlatform) 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';
}
Now I don't have mouch time for a 'pretty solution' , but in future I would like to restore the Doctrine classes and be able to assign the new column type into Symfony 2 bootstrap. 现在我没有时间来解决“漂亮的解决方案” ,但是将来我想恢复Doctrine类并能够将新的列类型分配给Symfony 2引导程序。 I think I should edit my app/bootstrap.php.cache but I don't have idea how to intervene. 我认为我应该编辑我的app / bootstrap.php.cache,但我不知道如何进行干预。
this worked for me: 这为我工作:
create your blobtype (See https://gist.github.com/525030/38a0dd6a70e58f39e964ec53c746457dd37a5f58 ) 创建您的Blob类型(请参阅https://gist.github.com/525030/38a0dd6a70e58f39e964ec53c746457dd37a5f58 )
add this to your Bundle initialization (/src/YOURDOMAIN/YOURBUNDLE/YOURDOMAINYOUBUNDLE.php) 将此添加到您的捆绑包初始化中(/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'); } }
Small improvement for registration blob type in XXXBundle::boot() , but can be necessary during unittests. 对XXXBundle :: boot()中的注册Blob类型进行小的改进,但在单元测试期间可能有必要。
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');
}
}
I just found this gist: https://gist.github.com/525030/38a0dd6a70e58f39e964ec53c746457dd37a5f58 我刚刚发现了这个要点: https : //gist.github.com/525030/38a0dd6a70e58f39e964ec53c746457dd37a5f58
app/bootstrap.php: app / bootstrap.php:
<?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 is auto-generated AFAIK.. So changes there would be overwritten. BTW bootstrap.cache.php是自动生成的AFAIK。因此更改将被覆盖。
