我有一个Usuario实体定义如下：
namespace Checkengine'DashboardBundle'Entity;
use Doctrine'ORM'Mapping as ORM;
use Doctrine'Common'Collections'ArrayCollection;
use Symfony'Component'Validator'Constraints as Assert;
use Symfony'Bridge'Doctrine'Validator'Constraints'UniqueEntity;
use Symfony'Component'Security'Core'User'UserInterface;
use Symfony'Component'HttpFoundation'File'UploadedFile;
use JMS'Serializer'Annotation as Serializer;
/**
* Usuario.
*
* @ORM'Table(name="usuarios")
* @ORM'Entity(repositoryClass="Checkengine'DashboardBundle'Repository'UsuarioRepository")
* @ORM'HasLifecycleCallbacks()
* @UniqueEntity("email")
*
* @Serializer'ExclusionPolicy("all")
*/
class Usuario implements UserInterface, 'Serializable
{
...
/**
* @var integer
*
* @todo No recibir ofertas del usuario.
*
* @ORM'ManyToMany(targetEntity="Checkengine'DashboardBundle'Entity'Empresa")
* @ORM'JoinTable(name="no_ofertas",
* joinColumns={@ORM'JoinColumn(name="usuario_id", referencedColumnName="id")},
* inverseJoinColumns={@ORM'JoinColumn(name="empresa_id", referencedColumnName="id")}
* )
*
* @Serializer'Expose
* @Serializer'Type("ArrayCollection<Checkengine'DashboardBundle'Entity'Empresa>")
* @Serializer'MaxDepth(1)
*/
private $noOfertas;
...
public function __construct()
{
$this->noOfertas = new ArrayCollection();
}
...
/**
* Add noOfertas.
* @param 'Checkengine'DashboardBundle'Entity'Empresa $noOfertas
* @return Usuario
*/
public function addNoOfertas(Empresa $noOfertas)
{
$this->noOfertas[] = $noOfertas;
return $this;
}
/**
* Remove noOfertas.
* @param 'Checkengine'DashboardBundle'Entity'Empresa $noOfertas
*/
public function removeNoOfertas(Empresa $noOfertas)
{
$this->noOfertas->removeElement($noOfertas);
}
/**
* Get noOfertas.
* @return 'Doctrine'Common'Collections'Collection
*/
public function getNoOfertas()
{
return $this->noOfertas;
}
}
每当我尝试更新Usuario时，我都会收到以下错误：
既不是属性"noOfertas"，也不是其中一个方法"addNoOferta（）"/"removeNoOferta，类中存在"__set（）"或"__call（）"并具有公共访问权限"Checkengine''DashboardBundle''Entity''Usuario"。
这是updateAction()方法：
public function updateAction(Request $request, $id)
{
$em = $this->getDoctrine()->getManager();
$entity = $em->getRepository('DashboardBundle:Usuario')->find($id);
if (!$entity) {
throw $this->createNotFoundException('Unable to find Usuario entity.');
}
$deleteForm = $this->createDeleteForm($id);
$editForm = $this->createEditForm($entity);
$current_pass = $entity->getPassword();
$editForm->handleRequest($request);
if ($editForm->isValid()) {
if (null == $entity->getPassword()) {
$entity->setPassword($current_pass);
} else {
$this->setSecurePassword($entity);
}
$em->flush();
return $this->redirect($this->generateUrl('usuarios_edit', array('id' => $id)));
}
return array(
'entity' => $entity,
'form' => $editForm->createView(),
'delete_form' => $deleteForm->createView(),
);
}
那里可能出了什么问题？我缺少什么？我已经清理了好几次缓存，还重新启动了Web服务器（以防万一），但仍然没有任何问题，这让我抓狂，有什么建议吗？线索
如错误消息所示，您需要添加/删除一个$noOferta对象，而不是整个集合$noOfertas。
你需要重写这样的方法：
public function addNoOferta(Empresa $noOferta)
{
$this->noOfertas[] = $noOferta;
return $this;
}
public function removeNoOferta(Empresa $noOferta)
{
$this->noOfertas->removeElement($noOferta);
}
