我如何添加一个角色给用户与形式symfony

Question

大家好我是新的symfony和有点卡住试图创建一个用户与他各自的角色，每次我尝试添加一个我得到这个错误：属性“可以使用方法“addRole（）”，“removeRole（）”来定义类“... \ Entity \ Usuarios”中的角色，但新值必须是\ Traversable的数组和/或“ \ Entity \ Roles“给出。

在我的数据库中的角色是ROLE_ADMIN和ROLE_USER，即所有的好，但不能注册一个用户与他在表单中的角色。

这是我Usuarios.php

UsuariosType.php

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 getBlockPrefix() 
{ 
    return 'paginas_usuariosbundle_usuarios'; 
} 


} 

和我Controller.php这样

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() 
)); 

不知道该怎么办，请问有人可以帮我

Answer 1

您需要传递一个角色数组而不是roles对象。在表单构建器中使用'multiple' => true和'roles`。

UsuariosType.php

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

Answer 2

定义你的角色在/app/config/security.yml此外，如果你需要，你可以添加更多的角色，像下面，

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] 

如果您需要在您的控制器中获得角色

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

如果您需要让角色进入FormType

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

和形式，（注意，这是一个例子多选择，你可以改变这种方式下拉，复选框，或你想要的）

->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, 
    ) 
)
