我有一个看起来像这样的集合。每个对象在＆＃34;天＆＃34;它是自己的＆＃34; day＆＃34;文献。它没有进一步细分。结构如下：

我想编辑嵌套在这个json中的事件字段。我怎么会这样做？我有一个日模型。但它没有进一步细分。我正在考虑使用findOneAndUpdate，但是我无法弄清楚如何向下钻取所以我在正确的时间段内。端点可以访问将事件设置为的日期，时间和值。

使用$运算符在数组
db.days.update(
{day: 'Monday', 'slots.time': '12:00am'}
{$set: {'slots.$.event': 'your new value'}}
);
