Mongoose 如何在mongodb中检索嵌套结构中的特定对象？

根据下面的结构，我想检索给定此shopName的第二个product对象。我只能考虑通过以下查询获取所有产品对象：

Shop.find（{shopName:shopName}）。选择（'products'）

。我怎样才能修改它来达到我想要的，谢谢

"shopName": "jmart",
"products": [{
        "id": 1,
        "name": "Clean and Clear Deep Clean Cleanser 100g",
        "slug": "8d1c895c-6911-4fc8-a34c-89c6948233d7",
        "price": 4.5,
        "discount_price": 0,
        "category": "Health and Beauty",
        "sale": false,
        "subcategory": "personal care",
        "color": "black",
        "article": "Clean and Clear",
        "quantity": 9,
        "img": "https://firebasestorage.googleapis.com/v0/b/swifty-products.appspot.com/o/Jmart%2FBeauty%2FClean%20and%20Clear%20Deep%20Clean%20Cleanser%20100g.jpg?alt=media",
        "vendor": {
            "id": 1,
            "name": "Clean and Clear"
        },
        "ratings": {
            "star_ratings": 0,
            "votes": 0
        },
        "isAvailable": true
    }, {
        "id": 2,
        "name": "Colgate Total Pro Breath Health",
        "slug": "67626dae-1537-40d8-837d-483e5759ada0",
        "price": 4.5,
        "discount_price": 0,
        "category": "Health and Beauty",
        "sale": false,
        "subcategory": "personal care",
        "color": "black",
        "article": "Colgate",
        "quantity": 9,
        "img": "https://firebasestorage.googleapis.com/v0/b/swifty-products.appspot.com/o/Jmart%2FBeauty%2FColgate%20Total%20Pro%20Breath%20Health.jpg?alt=media",
        "vendor": {
            "id": 2,
            "name": "Colgate"
        },
        "ratings": {
            "star_ratings": 0,
            "votes": 0
        },
        "isAvailable": true
    },
  ]

可以使用运算符返回第n个数组元素

{$slice:[，]}

const products=wait Shop.find(
{shopName:shopName}，
{products:{$slice:[1，1]}//跳过数组的第一个元素并返回下一个1元素
).选择（“产品”）；

hi@Vishnu，你认为我如何根据slug更新第二个元素中的特定字段？以下操作无效

Shop.find（{shopName:shopName}）.update（{products:{$elemMatch:{slug:slug}}}，{$set:{price:req.body.price}}
