This PR introduces a new constraint, `@AutoMapping` allowing to do exactly that. Examples: Class: ```php use Doctrine\ORM\Mapping as ORM; use Symfony\Component\Validator\Constraints as Assert; /** * @Orm\Entity * @Assert\AutoMapping(false) */ class DoctrineLoaderNoAutoMappingEntity { /** * @Orm\Id * @Orm\Column */ public $id; /** * @Orm\Column(length=20, unique=true) */ public $maxLength; } ``` Property: ```php namespace Symfony\Bridge\Doctrine\Tests\Fixtures; use Doctrine\ORM\Mapping as ORM; use Symfony\Bridge\Doctrine\Validator\Constraints\UniqueEntity; use Symfony\Component\Validator\Constraints as Assert; /** * @Orm\Entity */ class DoctrineLoaderEntity extends DoctrineLoaderParentEntity { /** * @Orm\Id * @Orm\Column */ public $id; /** * @Orm\Column(length=10) * @Assert\AutoMapping(false) */ public $noAutoMapping; } ``` The rules are the following: * If the constraint is present on a property, and set to true, auto-mapping is always on, regardless of the config, and of any class level annotation * If the constraint is present on a property, and set to false, auto-mapping is always off, regardless of the config, and of any class level annotation * If the constraint is present on a class, and set to true, auto-mapping is always on except if a the annotation has been added to a specific property, and regardless of the config * If the constraint is present on a class, and set to false, auto-mapping is always off except if a the annotation has been added to a specific property, and regardless of the config Commits ------- f6519ce [Validator] Add AutoMapping constraint to enable or disable auto-validation
