如何在猫鼬模式中存储对象？

Question

In node.js I have three variables:

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

And schema:

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

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

What type and how do I use it in schema? How is the best way for this?

Answer 1

The Solution to save array is much simple,Please check below code

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

Your schema will look like it

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

Answer 2

You must create another mongoose schema:

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

And the type of addresses will be Array< address >

Answer 3

You are actually storing an array.

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

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();

Hope this may solve your issue
