php - symfony2 の一意のバリデータは行を更新できません

Question

一意の変数を持つエンティティを作成しました。ORM を一意に設定し、バリデーターにも設定しました。これにより、一意の名前を持つ新しい行を作成できますが、更新するように指定しただけでも、既存の行を更新することはできません。

検証.yml:

# src/Battlemamono/DatabaseBundle/Resources/config/validation.yml

Battlemamono\DatabaseBundle\Entity\Mamono:
    constraints:
        - Symfony\Bridge\Doctrine\Validator\Constraints\UniqueEntity:

        description:

これを行うアクション:

public function editProccessAction($id, Request $request)
    {
        $form = $this->createForm(new MamonoType());
        if ($request->isMethod('POST'))
        {
            $form->bind($request);

            if ($form->isValid())
            {
                $FormData = $form->getData();
                $em = $this->getDoctrine()->getManager();
                $mamono = $em->getRepository('BattlemamonoDatabaseBundle:Mamono')->find($id);

                    if (!$mamono) {
                        $this->get('session')->getFlashBag()->add('notice', 'There is no such mamono in the database. Create it instead!');
                        return $this->redirect($this->generateUrl('battlemamono_database_create'));
                    }
                $mamono->setName($FormData->getName());
                $mamono->setFamily1($FormData->getFamily1());
                $mamono->setFamily2($FormData->getFamily2());
                $mamono->setElement1($FormData->getElement1());
                $mamono->setElement2($FormData->getElement2());
                $mamono->setDisposition($FormData->getDisposition());
                $mamono->setDiet($FormData->getDiet());
                $mamono->setPreviousForm($FormData->getPreviousForm());
                $mamono->setNextForm($FormData->getNextForm());
                $mamono->setEvolution($FormData->getEvolution());
                $mamono->setEvolutionLove($FormData->getEvolutionLove());
                $mamono->setTags($FormData->getTags());
                $mamono->setDescription($FormData->getDescription());
                $mamono->setUpdatedBy();
                $em->flush();

                $this->get('session')->getFlashBag()->add('notice', 'the Mamono was updated.');
                return $this->redirect($this->generateUrl('battlemamono_database_homepage'));
            }
            else
            {
                return new Response($form->getErrorsAsString());
            }
        }
    }

Answer 1

実際にはエンティティを保存していません:

//...
$mamono->save();
$em->flush();
