Question

我正在使用Symfony2。我想将一个参数从Controller传递给FormType：这是我的行动：

public function addAction(Request $request)
    {
        $employee = $this->getUser();
        if (null === $employee) {
            throw $this->createNotFoundException("L'employé est anonyme.");
        } else {
            $em = $this->getDoctrine()->getManager();
            $abs = new Absence();
            $form = $this->createForm(new AbsenceType($employee), $abs);
            if ($form->handleRequest($request)->isValid()) {
                    $employee->addAbsence($abs);
                    $em->persist($employee);
                    $em->flush();
                    $this->addFlash('notice', 'absence  bien enregistrée.');
                    return $this->redirect($this->generateUrl('pfe_time_absence_index'));
                }
            }
            return $this->render('PFETimeBundle:Absence:add.html.twig', array(
                'form' => $form->createView(),
            ));
    }

这是我的FormType：

class AbsenceType extends AbstractType
{
    protected $sup;
    public function __construct (  Employee $profile)
    {
        $this->sup = $profile;
    }
    public function buildForm(FormBuilderInterface $builder, array $options)
    {
        $supp=$this->sup;
        $builder
            ->add('employee', 'entity', array(
                'class' => 'PFEUserBundle:Employee',
                'property'=>'matricule',
                 'query_builder' => function(EmployeeRepository $er) use ($supp){
                 return $er->createQueryBuilder('e')
                    ->where("e.parent.matricule = :matricule")
                    ->orderBy('e.nom', 'ASC')
                    ->setParameter('matricule', $supp->getMatricule())
                    ;
                }
            ))
            ->add('dateDebut','date')
            ->add('dateFin','date')
            ->add('motif', 'choice', array(
                'expanded' => true,
                'multiple' => false,
                'choices'  => array('Non'=>'Non','Oui'=>'Oui'),))
            ->add('motif','textarea')
            ->add('valider','submit')
        ;
    }
    public function setDefaultOptions(OptionsResolverInterface $resolver)
    {
        $resolver->setDefaults(array(
            'data_class' => 'PFE\TimeBundle\Entity\Absence'
        ));
    }

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

查询获取员工的所有子项并将其传递给实体列表（我使用的是doctrine扩展名）。当我执行操作时，它给了我这个错误：

Catchable Fatal Error: Argument 1 passed to PFE\TimeBundle\Form\AbsenceType::PFE\TimeBundle\Form\{closure}() must be an instance of PFE\UserBundle\Entity\EmployeeRepository, instance of Gedmo\Tree\Entity\Repository\NestedTreeRepository given, called in C:\wamp\www\Projet\vendor\symfony\symfony\src\Symfony\Bridge\Doctrine\Form\ChoiceList\ORMQueryBuilderLoader.php on line 56 and defined

Answer 1

您获得的实际错误是query_builder关闭中的typehint存在问题。

function(EmployeeRepository $er) {}

您的关闭期望PFE\UserBundle\Entity\EmployeeRepository的实例，但正在接收Gedmo\Tree\Entity\Repository\NestedTreeRepository的实例

有几件事可能导致这种情况，但它可能是这两个中的一个

您的Employee实体未定义repositoryClass已定义here
您的EmployeeRepository课程不会继承Gedmo\Tree\Entity\Repository\NestedTreeRepository

所有这些，您应该查看Form Events这样的功能。
