如何根據請求更新 MongoDB 集合中的嵌套對象？

Question

我有下面給出的用戶集合

{
  "_id": 1
  "firstname": "John"
  "lastname": "Doe"
  "address": {
    "street": "13",
    "city": "Los Angeles",
    "state": "California",
    "country": "USA",
    "pincode": "12345"
  }
}

我想制作一個可以更新用戶數據的 API。

這是我嘗試過的：

第一種方法

使用此方法將從集合中刪除請求中不存在的某些字段。

詢問：

const updateUser = (userId, data) => {
    return UserDB.updateOne({ _id: userId }, {
        $set: {...data }
    });
};

要求：

{
  "_id": 1
  "firstname": "Justin"
  "lastname": "Thomas"
  "address": {
    "country": "Canada",
    "pincode": "9999"
  }
}

結果：

// street, city and state is removed from collection
{
  "_id": 1
  "firstname": "Justin"
  "lastname": "Thomas"
  "address": {
    "country": "Canada",
    "pincode": "9999"
  }
}

第二種方法：

使用此方法，將請求中不存在的字段設置為空。

詢問：

const updateUser = (userId, data) => {
    return UserDB.updateOne({ _id: userId }, {
        $set: {
            "firstname": data.firstname,
            "lastname": data.lastname,
            "address.street": data.address.street,
            "address.city": data.address.city,
            "address.state": data.address.state,
            "address.country": data.address.country,
            "address.pincode": data.address.pincode
        }
    });
};

要求：

{
  "_id": 1
  "firstname": "Justin"
  "lastname": "Thomas"
  "address": {
    "country": "Canada",
    "pincode": "9999"
  }
}

結果：

// street, city and state is set to null in the collection.
{
  "_id": 1
  "firstname": "Justin"
  "lastname": "Thomas"
  "address": {
    "street": null,
    "city": null,
    "state": null,
    "country": "Canada",
    "pincode": "9999"
  }
}
