如何在Laravel中使用embedsMany获取所有属性？只返回外键

Question

你好，开发人员，

我正在尝试实现jenssegers/laravel-mongodb

的embedMany关系

我有两个收藏夹：

• ProfileSection-{ "_id": "5c865ea4257db43fe4007331", "general_name": "MY_PROFILE", "type": "public", "points": 100, "status": 1, "translated": [ { "con_lang": "US-EN", "country_code": "US", "language": "EN", "text": "My Profile", "description": "My Profile" }, ... ], "updated_at": "2019-03-11T13:12:04.000Z", "created_at": "2019-03-11T13:12:04.000Z" }
• 个人资料问题-{ "_id": "5c865ea3257db43fe40072b2", "id": "STANDARD_EDUCATION", "general_name": "STANDARD_EDUCATION", "country_code": "US", "order": 1, "profile_section_id": "5c865ea4257db43fe4007331", "profile_section": "My Profile", "translated": [ { "con_lang": "US-EN", "text": "What is the highest level of education you have completed?", "hint": null, "mapping": {}, "answers": [ { "precode": "1", "text": "3rd Grade or less", "mapping": {} } ] }, {...} ], "updated_at": "2019-03-11T13:12:03.000Z", "created_at": "2019-03-11T13:12:03.000Z" }

在 ProfileSection 中，我已添加

public function questions()  
{  
    return $this->embedsMany(ProfilerQuestions::class, '_id', 'profile_section_id');  
}

如果我执行ProfileSection::find('5c865ea4257db43fe4007331')->questions 它返回给我带有仅一个属性的个人档案问题对象：5c865ea4257db43fe4007331，即个人档案部分

的 ObjectId

我在访问问题对象之前尝试使用->with('questions) 像this 但这不起作用

我不知道问题是什么，肯定需要一些帮助。
