Symfony2 SyliusRbacBundle角色分配错误:为foreach() NestedSetRolesRes - Symfony2 SyliusRbacBundle role asigment error: Invalid argument supplied for foreach() NestedSetRolesResolver.php

Symfony2 SyliusRbacBundle role asigment error: Invalid argument supplied for foreach() NestedSetRolesResolver.php

我正在与FOSUserBundle一起实现SyliusRbacBundle，我设置了一个安全区域，只是为了测试是否一切正常，但当我浏览到该路由时，我得到了以下错误:

CRITICAL - Uncaught PHP Exception Symfony'Component'Debug'Exception'ContextErrorException: "Warning: Invalid argument supplied for foreach()" at /home/daniel/web/tests/tmootb/vendor/sylius/rbac/Resolver/NestedSetRolesResolver.php line 48

当通过FosUserBundle创建用户时，列'authorization_roles'填充了以下信息:

Doctrine'Common'Collections'ArrayCollection@00000000318556cb000000002fabcd7d

我得到了这个错误，这不是一个数组或ArrayCollection预期。所以，我没有正确分配角色，但我不确定如何在用户创建或用户推广时做到这一点。下面是我的User模型:

/**
 * Class User
 * @package App'AppBundle'Entity
 * @ORM'Entity
 * @ORM'Table(name="users")
 */
class User extends BaseUser implements IdentityInterface
{
/**
 * @var
 *
 * @ORM'Id
 * @ORM'Column(type="integer")
 * @ORM'GeneratedValue(strategy="AUTO")
 */
protected $id;
/**
 * @var
 *
 * @ORM'Column(type="string")
 */
private $authorizationRoles;
public function __construct()
{
    parent::__construct();
    $this->authorizationRoles = new ArrayCollection();
}
/**
 * Get roles.
 *
 * @return RoleInterface[]
 */
public function getAuthorizationRoles()
{
    return $this->authorizationRoles;
}
/**
 * {@inheritdoc}
 */
public function addAuthorizationRole(RoleInterface $role)
{
    if (!$this->hasAuthorizationRole($role)) {
        $this->authorizationRoles->add($role);
    }
}
/**
 * {@inheritdoc}
 */
public function removeAuthorizationRole(RoleInterface $role)
{
    if ($this->hasAuthorizationRole($role)) {
        $this->authorizationRoles->removeElement($role);
    }
}
/**
 * {@inheritdoc}
 */
public function hasAuthorizationRole(RoleInterface $role)
{
    return $this->authorizationRoles->contains($role);
}
/**
 * {@inheritdoc}
 */
public function getRoles()
{
    $roles = parent::getRoles();
    foreach ($this->getAuthorizationRoles() as $role) {
        $roles = array_merge($roles, $role->getSecurityRoles());
    }
    return $roles;
}
}

我看了看他们是怎么做的:https://github.com/Sylius/Sylius/blob/master/src/Sylius/Component/Core/Model/User.php

我被困在那里了，任何见解都将是非常感激的。

谢谢!

原来我没有正确地添加关系，所以我没有用户和角色之间的中间表。我添加了如下注释:

    /**
     * @var
     *
     * @ORM'ManyToMany(targetEntity="Sylius'Component'Rbac'Model'RoleInterface")
     * @ORM'JoinTable(name="sylius_user_role",
     *      joinColumns={@ORM'JoinColumn(name="user_id", referencedColumnName="id", nullable=false, onDelete="CASCADE")},
     *      inverseJoinColumns={@ORM'JoinColumn(name="role_id", referencedColumnName="id", unique=true, nullable=false, onDelete="CASCADE")}
     *      )
     */
    private $authorizationRoles;

然后更新数据库，覆盖FOSUserBundle配置文件编辑表单，现在一切都工作了。
