Question

我只用了几天symfony 2。我有两个实体，我想创建一个表单并将此表单中的数据保存到数据库中。 UserDetails和Contract有关系OneToOne。我将一种形式的契约嵌入到UserDetails表单中（在web上形成apper），但是当我将一些数据设置为表单并单击“保存”按钮时，我收到错误。因为我注意到“尝试”分配数组而不是合同我不知道如何在Controler中访问这个新合同。

示例错误：

ContextErrorException：Catchable Fatal Error：传递给Leave \ DatabaseBundle \ Entity \ UserDetails :: setContract（）的参数1必须是Leave / DatabaseBundle \ Entity \ Contract的实例，给定数组，在/ var / www / nowyUrlop /中调用第360行的vendor / symfony / symfony / src / Symfony / Component / PropertyAccess / PropertyAccessor.php，在/var/www/nowyUrlop/src/Leave/DatabaseBundle/Entity/UserDetails.php第165行中定义

at UserDetails-＆gt; setContract（array（'start_contr'=＆gt; object（DateTime），'end_contr'=＆gt; object（DateTime），'hours_per_week'=＆gt;'6'））/ var / www /nowyUrlop/vendor/symfony/symfony/src/Symfony/Component/PropertyAccess/PropertyAccessor.php第360行

UserDetails实体：

use Doctrine\ORM\Mapping as ORM;
use Doctrine\Common\Annotations\AnnotationReader;
use Leave\DatabaseBundle\Entity\User;

/**
 * @ORM\Entity
 * @ORM\Table(name="userDetails")
 */
class UserDetails {

/**
 * @ORM\Id
 * @ORM\Column(type="integer")
 * @ORM\GeneratedValue(strategy="AUTO")
 */
protected $id;

/**
 * @ORM\OneToOne(targetEntity="Contract", mappedBy="user_details", cascade={"persist"})
 */
protected $contract;

/**
 * @ORM\OneToOne(targetEntity="User", inversedBy="userDetails")
 * @ORM\JoinColumn(name="user_id", nullable = true, referencedColumnName="id")
 * */
protected $user;

合同实体：

use Doctrine\ORM\Mapping as ORM;
use Symfony\Component\Validator\Constraints as Assert;

/**
 * @ORM\Entity
 * @ORM\Table(name="contract")
 */
class Contract {

/**
 * @ORM\Id
 * @ORM\Column(type="integer")
 * @ORM\GeneratedValue(strategy="AUTO")
 */
protected $id;

/**
 * @ORM\Column(type="date")
 */
protected $start_contr;

/**
 * @ORM\Column(type="date")
 */
protected $end_contr;

/**
 * @ORM\Column(type="integer")
 */
protected $type ;

/**
 * @ORM\Column(type="integer")
 */
protected $hours_per_week;

/**
 * @ORM\OneToOne(targetEntity="UserDetails", inversedBy="contract")
 * @ORM\JoinColumn(name="user_details_id", nullable = true, referencedColumnName="id")
 * */
protected $user_details;

public function setUserDetails(\Leave\DatabaseBundle\Entity\UserDetails $userDetails = null)
{
    $this->user_details = $userDetails;

    return $this;
}

/**
 * Get user_details
 *
 * @return \Leave\DatabaseBundle\Entity\UserDetails 
 */
public function getUserDetails()
{
    return $this->user_details;
}

UserDetals表格：

use Symfony\Component\Form\AbstractType;
use Symfony\Component\Form\FormBuilderInterface;
use Leave\DatabaseBundle\Form\Type\ContractFormType;

class UserDetailsFormType extends AbstractType
{
    public function buildForm(FormBuilderInterface $builder, array $options)
    {
        $builder->add('exp', 'text')
        ->add('total_leave', 'text')
        ->add('days_left', 'text')
        ->add('contract', new contractFormType())
        ->add('save', 'submit');
    }

    public function getName()
    {
        return 'userDetails';
    }
}

合同表格：

use Symfony\Component\Form\AbstractType;
use Symfony\Component\Form\FormBuilderInterface;

class ContractFormType extends AbstractType
{
public function buildForm(FormBuilderInterface $builder, array $options)
{
    $builder
        ->add('start_contr', 'date', array('widget' => 'single_text'))
        ->add('end_contr', 'date', array('widget' => 'single_text'))
        ->add('hours_per_week', 'text');
}   

public function getName()
{
    return 'contractForm';
}
}

控制器：

 public function editUserAction(Request $request) {

    $user = $this->get('security.context')->getToken()->getUser();
    $userDetails = new UserDetails();
    $form = $this->createForm(new UserDetailsFormType(), $userDetails);
    $userDetails->setUser($user);

    $form->handleRequest($request);

    if ($form->isValid()) {
        $em = $this->getDoctrine()->getManager();
        $em->persist($userDetails);
        $em->flush();

        return $this->render('LeaveEmployeeBundle:Employee:editUser.html.twig', array(
                    'formEditUser' => $form->createView(),
                    'userDetails' => $userDetails,
                    'user' => $user
            ));
    }
    return $this->render('LeaveEmployeeBundle:Employee:editUser.html.twig', array(
                'formEditUser' => $form->createView()
    ));
}

您必须将data_class作为第二个参数传递。

在您的UserDetals表格中：执行以下操作

use Symfony\Component\Form\AbstractType;
use Symfony\Component\Form\FormBuilderInterface;
use Leave\DatabaseBundle\Form\Type\ContractFormType;

class UserDetailsFormType extends AbstractType
{
   public function buildForm(FormBuilderInterface $builder, array $options)
   {
       $builder->add('exp', 'text')
       ->add('total_leave', 'text')
       ->add('days_left', 'text')
       ->add('contract', new contractFormType(), array(
        'data_class' => 'Leave\DatabaseBundle\Entity\Contract')
       )
       ->add('save', 'submit');
   }

   public function getName()
   {
      return 'userDetails';
   }
}
