Symfony 2 Console command for creating custom Database - mysql

Question

I am working on a Symfony 2 project where each user have his own database. In my config.yml file I have a doctrine:dbal:orm set for a client but no connection properties because they are set at runtime and referenced by all users. I.e I only have one default dbal connection and two orm-connection and the amount of users is unlimited.
This works fine but I need to create the database and schema when the user is registered (FOS UserBundle). In the extended userbundle controller I can put my own logic.
The problem is that I cannot run the 'php app/console doctrine:database:create' since there are not parameters set for the new user.
Is there any way of specifying a custom database parameter to the console commands?
I could probably get around this by some very ugly mysql commands but I'd rather not.
Many thanks in advance!

You can create your own command using the code below as an outline:
namespace Doctrine\Bundle\DoctrineBundle\Command;
use Symfony\Component\Console\Input\InputOption;
use Symfony\Component\Console\Input\InputInterface;
use Symfony\Component\Console\Output\OutputInterface;
use Doctrine\DBAL\DriverManager;
class CreateDatabaseDoctrineCommandDynamically extends DoctrineCommand
{
protected function configure()
{
$this
->setName('doctrine:database:createdynamic')
->setDescription('Creates the configured databases');
}
/**
* {#inheritDoc}
*/
protected function execute(InputInterface $input, OutputInterface $output)
{
/***
** Edit this part below to get the database configuration however you want
**/
$connectionFactory = $this->container->get('doctrine.dbal.connection_factory');
$connection = $connectionFactory->createConnection(array(
'driver' => 'pdo_mysql',
'user' => 'root',
'password' => '',
'host' => 'localhost',
'dbname' => 'foo_database',
));
$params = $connection->getParams();
$name = isset($params['path']) ? $params['path'] : $params['dbname'];
unset($params['dbname']);
$tmpConnection = DriverManager::getConnection($params);
// Only quote if we don't have a path
if (!isset($params['path'])) {
$name = $tmpConnection->getDatabasePlatform()->quoteSingleIdentifier($name);
}
$error = false;
try {
$tmpConnection->getSchemaManager()->createDatabase($name);
$output->writeln(sprintf('<info>Created database for connection named <comment>%s</comment></info>', $name));
} catch (\Exception $e) {
$output->writeln(sprintf('<error>Could not create database for connection named <comment>%s</comment></error>', $name));
$output->writeln(sprintf('<error>%s</error>', $e->getMessage()));
$error = true;
}
$tmpConnection->close();
return $error ? 1 : 0;
}
}
