Question

我正在尝试使用猫鼬更新或删除父文档中的子文档。

我的代码：

editSubscription(req, res) {
    const token = req.headers.authorization;
    jwt.verify(token, req.app.get('yourSecretKey'), function (err, payload) {
        userModel.update({ _id: payload.user._id, "subscriptions._id": req.params.id }, { "$set": { "subscriptions.$": req.body } }, function (err, obj) {
           console.log(obj)
       })
    })
}

console.log的输出是

{ n: 0, nModified: 0, ok: 1 }

我应该怎么做？我知道它的修改过的nModified是否返回1。我找不到任何有关如何解决或解决它的文档，以及我已经尝试过的关于stackoverflow的所有解决方案，都没有用。

我的收藏夹中的文档样本：

payload.user._id ==已验证的登录用户ID

req.params.id应该是尝试编辑的subscriptionId

尝试一下：

editSubscription(req, res) {
    const token = req.headers.authorization;
    jwt.verify(token, req.app.get('yourSecretKey'), function (err, payload) {
        userModel.update({ _id: ObjectId(payload.user._id), "subscriptions._id": ObjectId(req.params.id) }, { "$set": { "subscriptions.$": req.body } }, function (err, obj) {
           console.log(obj)
       })
    })
}
