如何修改集合实例？在 User 的 name 字段内容前加入 MyName

模型User.php

    protected $appends = ['name_label'];
    public function getNameAttribute($name)
    {
        return $this->prefix_name . $name;
    }

控制器App\User.php

    public function index()
    {
        dd(User::all());
    }

访问localhost/users //返回的是集合

  #appends: array:1 [ 0 => "name_label" ]
        "id" => 1
        "name" => "admin"
        "email" => "admin@qq.com"
        "created_at" => "2020-06-04 05:51:08"
        "updated_at" => "2020-06-04 05:51:08"
      ]
      #original: array:8 [▼
        "id" => 1
        "name" => "admin"
        "email" => "admin@qq.com"
        "created_at" => "2020-06-04 05:51:08"
        "updated_at" => "2020-06-04 05:51:08"
      ]

请问如何能够所有的返回name字段都加上个MyName呢？

 "name" => "MyNameadmin@qq.com"
