return $this; } /** * Get owner * * @return Acme\UserBundle\Entity\User */ public function getOwner() { return $this->owner; } } 现在我已经使用应用程序/控制台创建了一个玩家表单类，并且我已将团队字段编辑为团队实体的实例，如下所示： <?php namespace Acme\PlayerBundle\Form; use Acme\TeamBundle\Entity\TeamRepository; use Symfony\Component\Form\AbstractType; use Symfony\Component\Form\FormBuilderInterface; use Symfony\Component\OptionsResolver\OptionsResolverInterface; class PlayerType extends AbstractType { public function buildForm(FormBuilderInterface $builder, array $options) { $builder ->add('name') ->add('shirtNumber') ->add('firstname') ->add('lastname') ->add('role') ->add('team', 'entity', array( 'class' => 'AcmeTeamBundle:Team', 'query_builder' => function(TeamRepository $er) { $query = $er->createQueryBuilder('t'); return $query; } )); } public function setDefaultOptions(OptionsResolverInterface $resolver) { $resolver->setDefaults(array( 'data_class' => 'Acme\PlayerBundle\Entity\Player', 'csrf_protection' => false )); } public function getName() { return 'player'; } } 这是我的控制器的相关部分： /** * Create a new player * * @Route(".{_format}", name="api_player_create") * @Method("POST") * @ApiDoc( * description="Create a new player", * statusCodes={ * 201="Player created and informations are returned", * 400="Missing informations", * 403="The user isn't authorized" * }, * input="Acme\PlayerBundle\Form\PlayerType", * return="Acme\PlayerBundle\Entity\Player" * ) * * @return Renders the player just created */ public function createPlayerAction() { return $this->processForm(new Player()); } /** * Edit a player * * @param integer $id The id of the player to be created * * @Route("/{id}.{_format}", name="api_player_patch", requirements={ "id": "\d+" }) * @Method("PATCH") * @ApiDoc( * description="Edit a player", * statusCodes={ * 200="Player is updated", * 400="Missing informations", * 403="The user isn't authorized" * }, * input="Acme\PlayerBundle\Form\PlayerType", * return="Acme\PlayerBundle\Entity\Player" * ) * * @return Renders the player just edited */ public function editPlayerAction(Player $player) { if ($player->getOwner() != $this->getUser()) { throw new ApiException\PermissionDeniedException; } return $this->processForm($player); } /** * Function to handle a form to create/edit a player * * @param Player $player The player to be created or edited * * @return Api Response */ private function processForm(Player $player) { /** * Check if the player is new (to be created) or we're editing a player */ $statusCode = is_null($player->getId()) ? 201 : 200; $form = $this->createForm(new PlayerType(), $player); $form->bind($this->getRequest()); if ($form->isValid()) { if($player->getTeam()->getOwner() != $this->getUser()) { throw new ApiException\PermissionDeniedException; } $player->setOwner($this->getUser()); $this->entityManager->persist($player); $this->entityManager->flush(); return $this->apiResponse->getResponse($player, $statusCode); } return $this->apiResponse->getResponse($form, 400, 'Missing arguments'); } 播放器创建工作正常，播放器编辑则不然，当用户发出 api 请求时，传递 url 中的 ID 和我得到的播放器名称： Catchable Fatal Error: Argument 1 passed to Acme\PlayerBundle\Entity\Player::setTeam() must be an instance of Acme\TeamBundle\Entity\Team, null given, called in /Volumes/Dati/Users/alessandro/Sites/acme-api/vendor/symfony/symfony/src/Symfony/Component/Form/Util/PropertyPath.php on line 538 and defined in /Volumes/Dati/Users/alessandro/Sites/acme-api/src/Acme/PlayerBundle/Entity/Player.php line 278 似乎表单试图将团队设置为空，为什么？ 我尝试过发送而不是团队作为表单参数，但它不起作用。 有什么线索吗？ 发现表单中的 null 未发送字段是 symfony 中的默认行为。 在 symfony 中存在对部分表单绑定的开放请求。现在，一个人创建了一个表单事件订阅者，它用实际值添加了缺失的字段： https://gist.github.com/3720535 这是他的代码： <?php namespace Foo; use Symfony\Component\EventDispatcher\EventSubscriberInterface; use Symfony\Component\Form\FormEvents; use Symfony\Component\Form\FormEvent; /** * Changes Form->bind() behavior so that it treats not set values as if they * were sent unchanged. * * Use when you don't want fields to be set to NULL when they are not displayed * on the page (or to implement PUT/PATCH requests). */ class PatchSubscriber implements EventSubscriberInterface { public function onPreBind(FormEvent $event) { $form = $event->getForm(); $clientData = $event->getData(); $clientData = array_replace($this->unbind($form), $clientData ?: array()); $event->setData($clientData); } /** * Returns the form's data like $form->bind() expects it */ protected function unbind($form) { if ($form->hasChildren()) { $ary = array(); foreach ($form->getChildren() as $name => $child) { $ary[$name] = $this->unbind($child); } return $ary; } else { return $form->getClientData(); } } static public function getSubscribedEvents() { return array( FormEvents::PRE_BIND => 'onPreBind', ); } } 要添加到表单，您必须编辑表单类中的 buildForm 方法： public function buildForm(FormBuilderInterface $builder, array $options) { $subscriber = new PatchSubscriber(); $builder->addEventSubscriber($subscriber); $builder->add('name'); .... } 在这种情况下，您可以使用 PATCH REST 请求仅通过发送的字段来编辑实体
