我堅持和沮喪與波紋管的錯誤消息:可捕捉的致命錯誤:參數1傳遞給? Symfony2的
Catchable Fatal Error: Argument 1 passed to Medicine\UserBundle\Entity\User ::setUsertype() must be an instance of Medicine\UserBundle\Entity\Usertype, instance of Doctrine\Common\Collections\ArrayCollection given, called in /opt/lampp/htdocs/drugs/vendor/symfony/src/Symfony/Component/Form/Util /PropertyPath.php on line 347 and defined in /opt/lampp/htdocs/drugs/src/ Medicine/UserBundle/Entity/User.php line 224
我認爲這個錯誤是由於我的實體使用多對一場的,我甚至與另一個實體保持一對多嘗試。
我有一個用戶實體和一個usertype實體,usertype_id是用戶表中的manytoone字段。這裏是兩個實體的代碼: -
用戶
namespace Medicine\UserBundle\Entity;
use Doctrine\ORM\Mapping as ORM;
use Doctrine\Common\Collections\ArrayCollection;
/**
* @ORM\Entity(repositoryClass="Medicine\UserBundle\Repository\UserRepository")
* @ORM\Table(name="user")
* @ORM\HasLifecycleCallbacks()
*/
class User
{
/**
* @ORM\Id
* @ORM\Column(type="integer")
* @ORM\GeneratedValue(strategy="AUTO")
* @ORM\HasLifecycleCallbacks()
*/
protected $id;
/**
* @ORM\Column(type="string")
*/
protected $username;
/**
* @ORM\ManyToOne(targetEntity="Usertype", inversedBy="users")
* @ORM\JoinColumn(name="usertype_id", referencedColumnName="id")
*/
protected $usertype;
/**
* @ORM\Column(type="string")
*/
protected $image;
/**
* Set usertype
*
* @param Medicine\UserBundle\Entity\Usertype $usertype
*/
public function setUsertype(\Medicine\UserBundle\Entity\Usertype $usertype)
{
$this->usertype = $usertype;
}
/**
* Get usertype
*
* @return Medicine\UserBundle\Entity\Usertype
*/
public function getUsertype()
{
return $this->usertype;
}
}
我只是展示有關的代碼,我有所有上面的代碼的getter和setter方法。
用戶類型
namespace Medicine\UserBundle\Entity;
use Doctrine\ORM\Mapping as ORM;
use Doctrine\Common\Collections\ArrayCollection;
/**
* @ORM\Entity(repositoryClass="Medicine\UserBundle\Repository\UsertypeRepository")
* @ORM\Table(name="usertype")
* @ORM\HasLifecycleCallbacks()
*/
class Usertype
{
/**
* @ORM\Id
* @ORM\Column(type="integer")
* @ORM\GeneratedValue(strategy="AUTO")
* @ORM\HasLifecycleCallbacks()
*/
protected $id;
/**
* @ORM\Column(type="string")
*/
protected $name;
/**
* @ORM\OneToMany(targetEntity="User", mappedBy="usertype")
*/
protected $users;
public function __construct()
{
$this->users = new \Doctrine\Common\Collections\ArrayCollection();
}
/**
* Add users
*
* @param Medicine\UserBundle\Entity\User $users
*/
public function addUser(\Medicine\UserBundle\Entity\User $users)
{
$this->users[] = $users;
}
/**
* Get users
*
* @return Doctrine\Common\Collections\Collection
*/
public function getUsers()
{
return $this->users;
}
}
控制器
當用戶想要登錄時,該執行。他將填寫的用戶名密碼和用戶類型:
public function indexAction()
{
$entity = new User();
$form = $this->createForm(new LoginForm(), $entity);
$request = $this->getRequest();
if ($request->getMethod() == 'POST') {
$form->bindRequest($request);
if ($form->isValid()) {
echo "<pre>"; print_r($entity->getUsertype()); exit;
$em = $this->getDoctrine()
->getEntityManager();
$em->persist($entity);
$userrepository = $em->getRepository('MedicineUserBundle:User');
echo "<pre>"; print_r($entity->getUsertype()); exit;
$all = $userrepository->findOneBy(array('login' => $entity->getLogin(), 'password' => $entity->getPassword()));
if($all)
{
return $this->redirect($this->generateUrl('MedicineUserBundle_login'));
}
}
}
return $this->render('MedicineUserBundle:User:loginpage.html.twig',array(
'form' => $form->createView()
));
}
登錄表單
public function buildForm(FormBuilder $builder, array $options)
{
$builder
->add('login', 'text', array('label' => 'Username',))
->add('password','password')
->add('usertype', 'entity', array('class' => 'MedicineUserBundle:Usertype', 'property'=>'name', 'multiple' => true,))
;
}
我認爲問題在於您的LoginForm - 我們可以看到這個嗎? – jstephenson 2012-02-23 13:19:34
@jstephenson: - 我用登錄表單更新了我的問題 – ScoRpion 2012-02-23 13:25:18
