更新嵌套对象中的键

我有一个文档的另一个文档的值为“basicInfo”字段:

{
  "personId": "5b45b3700fdd1a14c9f",
  "basicInfo": {
    "name": "dave",
    "age": 25,
    "personAddress": {
      "city": "los angeles",
      "street": "hollywood",
      "streetNumber": 150,
      "zipCode": 90210
    },
    "active": true
  }
}

我只想用这个更新人名:

db.people.findAndModify({
    query: { "personId" : "5b45b3700fdd1a14c9f" },
    update: {"$set":{"basicInfo":{"name":"new name"}}}
})

这将替换基本信息…我想创建一个方法,用用户想要更改的字段发送一个JSON,并且只更改那些字段。
