如何使用表单symfony向用户添加角色

标签： php symfony

大家好我是symfony的新手，并且尝试创建一个具有各自角色的用户时有点困难，每次我尝试添加一个我都会收到此错误：类中的“角色”属性“... \ Entity \ Usuarios“可以使用方法”addRole（）“，”removeRole（）“定义，但新值必须是\ Traversable的数组和/或实例，”... \ Entity \ Roles“。

我的数据库中的角色是ROLE_ADMIN和ROLE_USER，这些都很好但是无法在表单中注册用户。

这是我的Usuarios.php 

<?php

}

UsuariosType.php 

<?php

namespace Paginas\UsuariosBundle\Form;

use Symfony\Component\Form\AbstractType;
use Symfony\Component\Form\FormBuilderInterface;
use Symfony\Component\OptionsResolver\OptionsResolver;
use Symfony\Component\Form\Extension\Core\Type\ChoiceType;
use Symfony\Component\Form\Extension\Core\Type\TextType;
use Symfony\Component\Form\Extension\Core\Type\CheckboxType;
use Paginas\UsuariosBundle\Entity\Roles;
use Paginas\UsuariosBundle\Form\RolesType;
use Symfony\Component\Form\Extension\Core\Type\PasswordType;
use Symfony\Bridge\Doctrine\Form\Type\EntityType;



class UsuariosType extends AbstractType
{
/**
 * {@inheritdoc}
 */
public function buildForm(FormBuilderInterface $builder, array $options)
{
    $builder->add('nombre')
    ->add('direccion')
    ->add('fechaNac', 'date', array(
        'label'   => 'FechaNacimiento',
        'format'  =>'dd MM yyyy',
        'years'   =>range(date('Y')-50,date('Y')-17),
        'required'=>true))
    ->add('username')       
    ->add('password', PasswordType::class, array(
        'label'=>'Contraseña'))         
    ->add('email')
    ->add('estado', CheckboxType::class, array(
        'label'=>'Activo',
        'required'=>false,))
    ->add('roles', EntityType::class, array(
        'class'=> 'PaginasUsuariosBundle:Roles',
        'choice_label'=>'nombre',));
}

/**
 * {@inheritdoc}
 */
public function configureOptions(OptionsResolver $resolver)
{
    $resolver->setDefaults(array(
        'data_class' => 'Paginas\UsuariosBundle\Entity\Usuarios'
    ));
}

/**
 * {@inheritdoc}
 */
public function getBlockPrefix()
{
    return 'paginas_usuariosbundle_usuarios';
}


}

和我的Controller.php 

public function agregarAction()
{   
$usuario=new Usuarios();
$form=$this->createForm(new UsuariosType(), $usuario);

$request = $this->getRequest();

if($request->getMethod() == 'POST')
{   
  $form->bind($this->getRequest());

  if($form->isValid())
  { 
    $usuario=$form->getData();      
    $cadena_salt = md5(uniqid(null, true));
    $usuario->setSalt($cadena_salt);

    $em=$this->getDoctrine()->getManager();
    $em->persist($usuario);
    $em->flush();

    $em=$this->getDoctrine()->getManager();
    $product=$em->getRepository('PaginasUsuariosBundle:Usuarios')->findALl();
    return $this->redirectToRoute('usuario_lista');
  }
}
return $this->render('PaginasUsuariosBundle:Default:crear_usuario.html.twig',
array('form' => $form->createView()
));

不知道该怎么做，有人可以帮我吗

您需要传递角色数组而不是roles个对象。在表单构建器中使用'multiple' => true和＃39; roles`。

<强> UsuariosType.php 

->add('roles', EntityType::class, array(
    'class'=> 'PaginasUsuariosBundle:Roles',
    'multiple' => true, // Allow multiple selection
    'choice_label'=>'nombre')
);

如果需要，还可以在/app/config/security.yml中定义您的角色，可以添加更多角色，如下所示

role_hierarchy:
    ROLE_ADMIN:         [ROLE_ADMIN]
    ROLE_SUPER_ADMIN:   [ROLE_SUPER_ADMIN, ROLE_ALLOWED_TO_SWITCH]
    ROLE_TEACHER:       [ROLE_TEACHER]
    ROLE_STUDENT:       [ROLE_STUDENT]
    ROLE_PARENT:        [ROLE_PARENT]

如果您需要在Controller中获得角色

$roles = $this->getParameter('security.role_hierarchy.roles');

如果您需要将角色转换为FormType 

$roles = $this->getParent('security.role_hierarchy.roles');

并在表单中，（注意这是多选的一个示例，您可以将其更改为下拉列表，复选框或根据需要）

->add('roles', ChoiceType::class, array(
    'attr'  =>  array('class' => 'form-control',
    'style' => 'margin:5px 0;'),
    'choices' => 
    array
    (
        'ROLE_ADMIN' => array
        (
            'Yes' => 'ROLE_ADMIN',
        ),
        'ROLE_TEACHER' => array
        (
            'Yes' => 'ROLE_TEACHER'
        ),
        'ROLE_STUDENT' => array
        (
            'Yes' => 'ROLE_STUDENT'
        ),
        'ROLE_PARENT' => array
        (
            'Yes' => 'ROLE_PARENT'
        ),
    ) 
    ,
    'multiple' => true,
    'required' => true,
    )
)
