Mongoose 变量键名 [英] Mongoose variable key name

问题描述

我有一个 mongo 对象，并希望通过 mongoose 为我的网络应用程序访问它.我定义的架构有一个 Object 存储用户 ID 和一个 3 级值(是的，可能或否).

I have a mongo object and wish to access it via mongoose for my web app. The schema I've defined has an Object storing user ids and a 3-level value (yes, maybe or no).

例如

"user_info": {
    "<id_value_1>": "y",
    "<id_value_2>": "n"
}

上面的 id_value_* 是用户会话 ID，因此是一长串随机字符.如何为此创建 mongoose Schema ?

The id_value_*s above are the users session ids so a long string of random characters. How can I create a mongoose Schema for this?

1. user_info: {String, String} 会起作用吗?

我可以重构它，以便 user_info 是一个对象数组 { "sessionid": "<value>", "value: "y"}，这没问题，这是最好的选择吗?

I could restructure it so that the user_info is an array of objects { "sessionid": "<value>", "value: "y"}, which would be ok, is this the best option?

推荐答案

如果您在架构中避免使用动态键并采用您的第二个想法:

You'll be better off if you avoid dynamic keys in your schema and go with your second idea of:

user_info: [{sessionid: String, value: String}]

您可以使用 $ 位置运算符来更新单个 user_info 数组元素按 sessionid.

You can use the $ positional operator to update individual user_info array elements by sessionid.
