我正在使用代码点火器创建一个CRM系统。执行特定功能有几个角色。这两个角色是公司管理员和超级管理员。公司管理员只能为其公司创建用户。而super admin可以通过访问该公司管理员的管理面板为任何公司创建用户。当我尝试将用户添加为公司管理员时，它工作正常，但当我尝试从公司管理员添加用户时，当我点击添加用户按钮时，它会给出＆＃34;当前无法处理此请求。＆＃ 34;错误而不是加载添加用户视图
添加用户视图：
public static List<User> FilterDistinct<TKey>(this IEnumerable<User> source, Func<User, TKey> keySelector)
{
return source
.Where(x => keySelector(x) != null && keySelector(x).ToString() != string.Empty)
.GroupBy(keySelector)
.Select(g => g.First())
.ToList();
}
调用添加用户页面的控制器功能：

<div class="quick-links-holder">
<div class="inner">

加载添加用户视图的按钮：
public function adduser ($data=FALSE){
$data['logo']= $this->site_logo();
$data['company_name']=$this->site_company_name();
$data['fullname']=$this->site_user_full_name();
$data['picture']=$this->user_picture();
$data['logo']= $this->site_logo();
$data['menu'] = header_menu();
$data['dropdownItems'] = $this->TasksModel->get_dropdownItems();
$data['employees']=$this->AdminModel->load_employees();
$this->load->view('html/header',$data);
$this->load->view('add_user', $data);
$this->load->view('html/footer');
}
