Javascript深度合并中断objectid

Question

我对javascript并不陌生，但这是我第一次使用node.js。我正在尝试创建一个基本的查询来提供给mongoose，然后在稍后添加条件。我使用deepmerge将这些散列合并在一起，但是objectid被破坏了。

原始哈希：

query = {
        $and: [
            {"unsubscribe.status": { "$ne": "unsubscribed" }},
            {"isDeleted.status": { "$ne": true }},
            {'advisorCommunities': { $in: communities }},
            {"memberType": 'Advisor'}
        ]
    }

控制台目录：

  '$and': [
    { 'unsubscribe.status': { '$ne': 'unsubscribed' } },
    { 'isDeleted.status': { '$ne': true } },
    {
      advisorCommunities: {
        '$in': [
          ObjectID {
            _bsontype: 'ObjectID',
            id: Buffer(12) [Uint8Array] [
               93,   2, 154,  46,  92,
              186,  99,   7, 226, 238,
              107, 170
            ]
          }
        ]
      }
    },
    { memberType: 'Advisor' }
  ]
}

要合并的哈希：

engageQuery = {
  '$and': [
    {
      '$or': [
        { nextEngagementDate: { '$exists': false } }
      ]
    }
}

var deepmerge = require('deepmerge');
query = deepmerge(engageQuery, query);

advisorCommunities已更改：

{
  '$and': [
    {
      '$or': [
        { nextEngagementDate: { '$gte': 2021-06-10T15:17:54.627Z } },
        { nextEngagementDate: { '$exists': false } }
      ]
    },
    { 'unsubscribe.status': { '$ne': 'unsubscribed' } },
    { 'isDeleted.status': { '$ne': true } },
    {
      advisorCommunities: {
        '$in': [
          {
            _bsontype: 'ObjectID',
            id: {
              '0': 93,
              '1': 2,
              '2': 154,
              '3': 46,
              '4': 92,
              '5': 186,
              '6': 99,
              '7': 7,
              '8': 226,
              '9': 238,
              '10': 107,
              '11': 170
            }
          }
        ]
      }
    },
    { memberType: 'Advisor' }
  ]
}

这是来自mongoose的错误：

(node:34291) UnhandledPromiseRejectionWarning: CastError: Cast to string failed for value "{
  _bsontype: 'ObjectID',
  id: {
    '0': 93,

    '5': 186,
    '6': 99,
    '7': 7,

    '10': 107,
    '11': 170
  }

我花了一个小时尝试一些奇怪的东西来创建自定义函数，等等，但失败了。请帮帮忙。谢谢!

Answer 1

我回答了我自己的问题，但我不确定这是正确的答案。

query = deepmerge(engageQuery, query, {clone: false});

https://www.npmjs.com/package/deepmerge

将clone: false添加到选项修复了这个问题。但是，根据npm文档，该选项已被弃用。有人知道做这件事的正确方法吗？

在is-plain-object模块中使用isMergeableObject选项可能会更好。官方例子：

const isPlainObject = require('is-plain-object')
 
function SuperSpecial() {
    this.special = 'oh yeah man totally'
}
 
const instantiatedSpecialObject = new SuperSpecial()
 
const target = {
    someProperty: {
        cool: 'oh for sure'
    }
}
 
const source = {
    someProperty: instantiatedSpecialObject
}
 
const defaultOutput = merge(target, source)
 
defaultOutput.someProperty.cool // => 'oh for sure'
defaultOutput.someProperty.special // => 'oh yeah man totally'
defaultOutput.someProperty instanceof SuperSpecial // => false
 
const customMergeOutput = merge(target, source, {
    isMergeableObject: isPlainObject
})
