mongoose 字符串数组 [英] mongoose array of array of strings

问题描述

我希望 Mongoose Schema 属性包含一个字符串数组，就像这样

I wish to have a Mongoose Schema property contain an array of array of strings, like so

[['one','two','three'],['four','five']]

我应该如何在我的架构中建模?以下似乎不起作用，但它可能是另一个错误...

How should I model this in my Schema? The following doesn't seem to work but it could possibly be another error...

names : [[{type: String, trim: true}]]

我是否必须按照 Mongoose 中的嵌套数组

谢谢

推荐答案

啊，原来嵌套数组必须放在单独的模式中

Ah, it turns out that nested arrays do have to be put in seperate schemas

var InnerArray = new mongoose.Schema({
  set : [{type: String, trim: true}]
})

var Stuff = new mongoose.Schema({
foo : [InnerArray]
})
