Php 如何在laravel多个一对多关系中获取结果基于用户角色获取数据

我正在根据我的要求创建自定义ACL。但在这两者之间，我附加了一个数据库设计，其中用户只能属于一个部门，只能拥有该部门的一个角色，但可以在该部门拥有多个权限。但现在，当我试图获取针对用户角色的权限时，却显示了一个空数组，其中在数据库中有正确的条目

控制器中的控制器方法，其中是

dd（$data['getUserRoles']）返回以下结果空权限数组如何获取分配给特定角色的权限列表

 public function index()
{

    $user = new User();

    $user_id = Auth::id();

    $admin_user = $user->isAdmin();

    $assigned_roles = array();

    if (!$admin_user) {

        $data['getUserRoles'] = User::with('roles', 'permissions')->where('users.id', $user_id)->get();


        dd($data['getUserRoles']);

        foreach($data['getUserRoles'][0]->roles as $roles){

            $assigned_roles[] =  $roles->slug;
        }

        $data['assigned_roles'] = $assigned_roles;

        $data['departments'] =  Department::all();

    } elseif ($admin_user) {

        $data['getUserRoles'] = $user->getUserWithRoles();

        $data['departments'] =  Department::all();
    }

    $data['status'] =  array('Active', 'Inactive', 'Blocked');

    return view('users.users_list', $data);
}

结果

用户模型

class User extends Authenticatable
{
 public function getUserWithRoles(){

    $getUserWithRoles = User::with('roles', 'permissions')->get();

    return $getUserWithRoles;
}

public function isAdmin(){

    return Auth::user()->roles()->where('name', 'admin')->exists();
}

public function department()
{
    return $this->belongsTo('App\Models\Department');
}
public function givePermissionsTo($permissions) {
    $permissions = $this->getAllPermissions($permissions);
    if($permissions === null) {
        return $this;

榜样

class Role extends Model
{

public function permissions() {
    return $this->belongsToMany(Permission::class,'roles_permissions');
}


public function allRoles(){

    $all_roles = Role::leftJoin('roles_permissions', function($join) {

}

}如何获得用户？！您创建了一个用户模型，但它是空的，因为您创建了一个新的用户模型，但它是从数据库中获取的
