Question

在node.js中我有三个变量：

var name = 'Peter';
var surname = 'Bloom';
var addresses = [
    {street: 'W Division', city: 'Chicago'},
    {street: 'Beekman', city: 'New York'},
    {street: 'Florence', city: 'Los Angeles'},
];

架构：

var mongoose = require('mongoose')
  , Schema = mongoose.Schema;

var personSchema = Schema({
  _id     : Number,
  name    : String,
  surname : String,
  addresses : ????
});

什么类型以及如何在架构中使用它？最好的方法是什么？

Answer 1

保存数组的解决方案非常简单，请查看下面的代码

Adv.save({addresses: JSON.stringify(addresses)})

您的架构看起来像

var personSchema = Schema({
 _id     : Number,
 name    : String,
 surname : String,
 addresses : String,
});

Answer 2

您必须创建另一个mongoose架构：

var address = Schema（{ street：String， city：String}）;

地址类型为数组＆lt;地址＆gt;

Answer 3

您可以在personSchema中使用ref

x, y, z
-10,4,30
-4,3,20
10,10,12
-11.5,3,-33.2
-5,0,23
-4,-2,8
0,2,1
5,12,42
11.2,5,23

'ref'用于引用地址，并用于personSchema

Answer 4

//Your Schema is very easy like below and no need to define _id( MongoDB will automatically create _id in hexadecimal string)
var personSchema = Schema({
  name    : String,
  surname : String,
  addresses : [{
    street: String,
    city: String
  }]

var addresses= [
    {street: 'W Division', city: 'Chicago'},
    {street: 'Beekman', city: 'New York'},
    {street: 'Florence', city: 'Los Angeles'}
];
//Saving in Schema
var personData = new personSchema ({
  name:'peter',
  surname:'bloom',
  addresses:addresses  
})
personData.save();

希望这可以解决您的问题
