Question

这是来自mongodb数据库的集合，我使用node调用API。首先，我想澄清一些事情：第一个父ID被称为CategoryId，而在items数组中，该ID被称为ItemId。

{
  "_id": "5c9dc6b29d30be2ac7a4539f",
  "name": "Salads",
  "description": "",
  "isImage": 4,
  "iCnt": 3,
  "items": [
    {
      "_id": "5c9dcc17c4437434948b7d81",
      "name": "Green Salad",
      "description": "Freshly cut vegetables",
      "price": 10,
      "nonVeg": "No",
      "icon_id": "",
      "isSpecial": "No",
      "topping_id": "",
      "isImage": 0,
      "type": "i",
      "liked": 0,
      "likes": 5
    },
    {
      "_id": "5c9dc0b2fb23f429fe80adcc",
      "name": "Brinjol & Cottage cheese salad",
      "description": "Deep fried brinjol and cottage cheese",
      "price": 15,
      "nonVeg": "No",
      "icon_id": "",
      "isSpecial": "No",
      "topping_id": "",
      "isImage": 0,
      "type": "i",
      "liked": 0,
      "likes": 6
    }
  ]
}

我想更新_id: "5c9dcc17c4437434948b7d81"（名称是Green Salad）数据，但是它使用Node.js代替了整个项目数组。有人可以帮忙吗？

itemUpdate = function (req, res) {
  categoryModel.findByIdAndUpdate(req.params.id, { $set: req.body }, function (err, itemModel) {
    if (err) return next(err);
    res.send('item udpated.');
  });
};

或

itemUpdate = function (req, res) {
  ({ "_id": req.params.categoryId, "items_id": req.params.itemId },
    { $pull: { "items._id": { "_id": req.params.id } } },
    false,
    true

  );
}

这是我使用邮递员的req.body：-

{
    "name": "Chicken Soup",
    "description": "yumee Chicken ",
    "price": 10,
    "nonVeg": "Yes",
    "icon_id": "",
    "isSpecial": "No",
    "topping_id": "",
    "isImage": 0,
    "type": "i",
    "liked": 0,
    "likes": 5,
    "categoryId":"5c9dc6b29d30be2ac7a4539f",
    "itemId":"5c9dcc17c4437434948b7d81"

}

如何使用node js在猫鼬中使用嵌套ID更新嵌套数组？
