php - 如何使用表单在 symfony 2 中编辑用户权限？

Question

我在 symfony 2 + FOSUserBundle 中创建新的/编辑用户表单时遇到问题。我想让管理员能够从下拉列表或单选按钮列表中选择用户角色，但我似乎无法让它工作。我在这里找到了这个答案 How can I pass a full security roles list/hierarchy to a FormType class in Symfony2?这是我能找到的最相关的东西，但它不起作用。

这是当前的 UserType 表单。我想从容器中获取角色，但如果不抛出错误，我似乎也无法让它工作。角色将正确填充下拉列表，但它不会显示当前分配的角色，并且不允许更新信息，因为它希望它是一个数组 $entity->addRoles(array('ROLE_SUPER_ADMIN '));，但它只是作为字符串提交。

namespace Wes\AdminBundle\Form;

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

class UserType extends AbstractType
{
    private $roles;

    public function __construct($roles) {
        $this->roles = $roles;
    }

    public function buildForm(FormBuilderInterface $builder, array $options)
    {
        $builder
            ->add('username')
            ->add('email')
            ->add('enabled')
            ->add('roles', 'choice', array(
               'choices' => $this->flattenArray($this->roles),
            ))
            ->add('firstName')
            ->add('lastName')
        ;
    }

    public function setDefaultOptions(OptionsResolverInterface $resolver)
    {
        $resolver->setDefaults(array(
            'data_class' => 'Wes\AdminBundle\Entity\User',
            'roles' => null,
            'userRole' => null,
        ));
    }

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

    private function flattenArray(array $data)
    {
        $returnData = array();

        foreach($data as $key => $value)
        {
            $tempValue = str_replace("ROLE_", '', $key);
            $tempValue = ucwords(strtolower(str_replace("_", ' ', $tempValue)));
            $returnData[$key] = $tempValue;
        }
        return $returnData;
    }
}

这是 Controller 。

public function editAction($id)
{
    $em = $this->getDoctrine()->getManager();

    $entity = $em->getRepository('WesAdminBundle:User')->find($id);
    if (!$entity) {
        throw $this->createNotFoundException('Unable to find User entity.');
    }

    $editForm = $this->createForm(new UserType($this->container->getParameter('security.role_hierarchy.roles')), $entity);
    $deleteForm = $this->createDeleteForm($id);

    return $this->render('WesAdminBundle:User:edit.html.twig', array(
        'entity'      => $entity,
        'edit_form'   => $editForm->createView(),
        'delete_form' => $deleteForm->createView(),
    ));
}

/**
 * Edits an existing User entity.
 *
 */
public function updateAction(Request $request, $id)
{
    $em = $this->getDoctrine()->getManager();

    $entity = $em->getRepository('WesAdminBundle:User')->find($id);

    if (!$entity) {
        throw $this->createNotFoundException('Unable to find User entity.');
    }

    $deleteForm = $this->createDeleteForm($id);
    $editForm = $this->createForm(new UserType($this->container->getParameter('security.role_hierarchy.roles')), $entity);
    $editForm->bind($request);

    if ($editForm->isValid()) {
        $em->persist($entity);
        $em->flush();

        return $this->redirect($this->generateUrl('wes_admin_user_edit', array('id' => $id)));
    }

    return $this->render('WesAdminBundle:User:edit.html.twig', array(
        'entity'      => $entity,
        'edit_form'   => $editForm->createView(),
        'delete_form' => $deleteForm->createView(),
    ));
}

这几天我一直在和它作斗争，但我似乎无法让它正常工作。有什么想法吗？

使用 FOSUserBundle 提供的 userManager 而不是自定义持久化方法，因为角色数组在存储到数据库之前需要序列化。

$userManager = $this->container->get('fos_user.user_manager');
$user = $userManager->findUserBy(array('id' => $id));

$editForm = $this->createForm(new UserType($this->container->getParameter('security.role_hierarchy.roles')), $user);

if ($editForm->isValid()) {
    $userManager->updateUser($user);

    return $this->redirect($this->generateUrl('wes_admin_user_edit',
        array('id' => $id)));
}
