Add TINYINT to Doctrine SQL types

Following Symfony doc, I tried to add TINYINT as entity column type.

So far it works well, but two problem remain…

  1. Each time I want to perform a migration, Doctrine can’t reconize TINYINT for the associated columns, and perform the migration queries again.

  2. In form builders, by default TINYINT is reconized as TextType and not NumberType

Do you know what I’m missing to fix those two issues?

TinyintType.php

use DoctrineDBALParameterType;
use DoctrineDBALPlatformsAbstractPlatform;
use DoctrineDBALTypesType;

class TinyintType extends Type {
    const TINYINT='tinyint';

    /**
     * @return string
     */
    public function getName() {
        return self::TINYINT;
    }

    /**
     * @param array $fieldDeclaration
     * @param AbstractPlatform $platform
     * @return string
     */
    public function getSQLDeclaration(array $fieldDeclaration, AbstractPlatform $platform) {
        return $fieldDeclaration['unsigned'] === true ? 'TINYINT(1) UNSIGNED' : 'TINYINT(1)';
    }

    public function canRequireSQLConversion() {
        return true;
    }

    /**
     * @param $value
     * @param AbstractPlatform $platform
     * @return int|null
     */
    public function convertToPHPValue($value, AbstractPlatform $platform) {
        return $value === null ? null : (int)$value;
    }

    /**
     * @param mixed $value
     * @param AbstractPlatform $platform
     * @return int|mixed|null
     */
    public function convertToDatabaseValue($value, AbstractPlatform $platform) {
        return $value === null ? null : (int)$value;
    }

    /**
     * @return int
     */
    public function getBindingType() {
        return ParameterType::INTEGER;
    }
}

doctrine.yaml

doctrine:
    dbal:
        url: '%env(resolve:DATABASE_URL)%'
        server_version: '5.7'
        types:
            tinyint: 'AppDoctrineDBALTypesTinyintType'
    orm:
        auto_generate_proxy_classes: true
        naming_strategy: doctrine.orm.naming_strategy.underscore_number_aware
        auto_mapping: true
        mappings:
            App:
                is_bundle: false
                type: annotation
                dir: '%kernel.project_dir%/src/Entity'
                prefix: 'AppEntity'
                alias: App
