Mongoose仅更新多个嵌套数组中已更改的数据字段

我有一个像这样的收藏

我有一个api,它用这样的json响应

    "hidden": false,

}

在前端用户更改 hidden 字段中的任意一个 true 或 false 并返回相同的json对象和更新的 隐藏的 领域。

现在,我如何只更新NodeJS Mongoose中更改的值,即一些 隐藏的 字段从 符合事实的 到 错误的 反之亦然。

我和 Array Update Operators 但我想不出我的情况。正如你可能也看到的, location 和 profiles 嵌套在 basics 然而,其他人则在模式之外。

这是我的路线和登录,

router.post('/hidden/:id', function(req, res, next) {
  let changedResume = req.body
  if(changedResume.profiles.length) {
    console.log('there is profile')
    changedResume.profiles.forEach(elem => {
      console.log(elem)
      Resume.findByIdAndUpdate(
        { "_id" : new ObjectId(changedResume.id), "basics.profiles._id": new ObjectId(elem.id)},
        { "$set": { "basics.profiles.$[element].hidden": elem.hidden}},
        { "arrayFilters": [{"element._id": new ObjectId(elem.id)}], "upsert": true}, 
        function(err, docs) {
          if (err){ 
            console.log(err) 
          } 
          else{ 
              console.log("Updated User : ", docs); 
          } 
        }
        )
    })
  }

有了这个控制器,我将不得不一个接一个地检查所有阵列(上面只显示了配置文件),并更新所有用户甚至没有更改的阵列。有没有其他方法可以只更新更改的数据?

• how to get only the “changed” values from two JSON objects -这会让javascript代码获得两个对象(json或数组)之间的差异,但只会给出更改的内容,在我的例子中,它只会返回 隐藏的 ,没有 id s
