我更新了代码的不足部分：

function updatePermissions(Request $request)
{
    if (!hasRole('SuperAdmin') && !userCan('attach_permissions')) {
        abort('404');
    }

    $roleId = $request->input('role_id');
    $permIds = $request->input('perm');
    $role = Role::where('id', '=', $roleId)->first();
    if (!$role) {
        abort('404');
    }
    if ($permIds == null) {
        $role = Role::findOrFail($roleId);
        $role_permissions = $role->perms()->get();
        //print_r($role_permissions);exit;
        $rolePermIds = array();
        foreach ($role_permissions as $permission) {
            $rolePermIds[] = $permission->id;
        }
        $role->perms()->detach($rolePermIds);
    } else {
        /*$role->perms()->sync(array_keys($permIds));*/
        $permissions_new = (array_keys($permIds));
        RolePermission::where('role_id', '=', $roleId)->forceDelete();
        foreach ($permissions_new as $item) {
            $r = new RolePermission();
            $r->role_id = $role->id;
            $r->permission_id = $item;
            $r->save();
        }
    }
    return redirect()->back();
}

是否可以在数组列表中过滤结果，然后将该列表添加到数组适配器？
