使Laravel中关系的唯一结果成为对象,而不是数组中的对象

在数组内的对象中获取相关用户结果的查询

$members = CalendarMembers::with("user")
    ->where('calendar_id', $calendar[0]->calendar_id)
    ->get();

有这种关系

public function user()
{
    return $this->hasMany(Users::class, "id", "user_id");
}

结果是

"status": "200",
"success": true,
"data": [
    {
        "member_id": 4,
        "calendar_id": 4,
        "invited_by": null,
        "color": "#7D96E1",
        "role": "parent",
        "added_at": "2018-02-07 09:06:49",
        "user": [
            {
                "id": 4,
                "name": "User Name",
                "email": "username@gmail.com",
                "first_name": "User",
                "last_name": "Name",
                "status": "active",
                "is_activated": 0,
                "created_at": "2018-02-07 09:06:49",
                "updated_at": "2018-02-07 09:06:49"
            }
        ]
    },

但永远都是这样 User ,因此我试图改变 user 对于简单对象:

"status": "200",
"success": true,
"data": [
    {
        "member_id": 4,
        "calendar_id": 4,
        "invited_by": null,
        "color": "#7D96E1",
        "role": "parent",
        "added_at": "2018-02-07 09:06:49",
        "user": {
                "id": 4,
                "name": "User Name",
                "email": "username@gmail.com",
                "first_name": "User",
                "last_name": "Name",
                "status": "active",
                "is_activated": 0,
                "created_at": "2018-02-07 09:06:49",
                "updated_at": "2018-02-07 09:06:49"
            }
    },

但没有找到解决方案。
