Doctrine custom type always altering table

Question

I have added a custom type like:

namespace My\\SuperBundle\\Types;

use Doctrine\\DBAL\\Types\\Type;
use Doctrine\\DBAL\\Platforms\\AbstractPlatform;

class Mo         


        

Answer 1

You are not telling the DBAL platform about your type, so obviously, the DBAL schema introspection utilities cannot recognize it. To register the type, you can do following:

use Doctrine\DBAL\Types\Type;
use My\SuperBundle\Types\Money;

class MyBSuperBundle extends Bundle
{
    public function boot()
    {
        /* @var $em \Doctrine\ORM\EntityManager */
        $entityManager = $this->container->get('doctrine.orm.entity_manager');

        if( ! Type::hasType(Money::MONEY)) {
            Type::addType(Money::MONEY, 'My\SuperBundle\Types\Money');
            $entityManager
                ->getConnection()
                ->getDatabasePlatform()
                ->registerDoctrineTypeMapping('decimal', Money::MONEY);
        }
    }
}

This should stop the DBAL from complaining about schema differences.

Answer 2

I had the same problem with ZF2.

I solved it removing the hyphen in my custom type name.

Wrong:

'doctrine_type_mappings' => [
    'custom-type' => 'custom-type'
],

Good:

'doctrine_type_mappings' => [
    'customtype' => 'customtype'
],

I hope this can help someone.

Answer 3

There's an alternative way to do this using configurations.

config.yml:

doctrine:
    dbal:
        types: { money: My\SuperBundle\Types\Money }

    connections:
        your_connection_name:
            mapping_types: { money: money }

Answer 4

You have to override the method requiresSQLCommentHint(AbstractPlatform $platform) and return true. Like that, doctrine will remember the custom type.

namespace My\SuperBundle\Types;

use Doctrine\DBAL\Types\Type;
use Doctrine\DBAL\Platforms\AbstractPlatform;

class Money extends Type
{
    const MONEY = 'money';

    public function getSqlDeclaration(
        array $fieldDeclaration,
        AbstractPlatform $platform
    ) {
        return 'DECIMAL(10,2)';
    }

    public function getName()
    {
        return self::MONEY;
    }

    /**
     * @inheritdoc
     */
    public function requiresSQLCommentHint(AbstractPlatform $platform)
    {
        return true;
    }
}
