猫鼬模型分离
是Node和mongodb的新手。我有以下猫鼬模型。
import { model, Schema } from 'mongoose';
import Joi from '@hapi/joi';
const profileSchema = new Schema({
user: {
type: Schema.Types.ObjectId,
ref: 'users',
},
handle: {
type: String,
minlength: 2,
maxlength: 20,
required: true,
trim: true,
},
company: {
type: String,
minlength: 1,
maxlength: 100,
trim: true,
},
website: {
type: String,
maxlength: 100,
trim: true,
},
location: {

maxlength: 50,
trim: true,
required: true,
},

type: [String],
required: true,
},

type: String,
maxlength: 500,
trim: true,
},
githubUserName: {
type: String,
maxlength: 50,
trim: true,
},
experience: [
{
title: {
type: String,
maxlength: 100,
trim: true,
required: true,
},
company: {
type: String,
maxlength: 100,
trim: true,
required: true,
},
location: {
type: String,
maxlength: 100,
trim: true,
required: true,
},
from: {
type: Date,
required: true,
},
to: {
type: Date,
},
current: {
type: Boolean,
default: false,
},
description: {
type: String,
maxlength: 500,
trim: true,
},
},
],
education: [
{
school: {
type: String,
maxlength: 100,
trim: true,
required: true,
},
degree: {
type: String,
maxlength: 100,
trim: true,
required: true,
},
fieldOfStudy: {
type: String,
maxlength: 100,
trim: true,
required: true,
},
from: {
type: Date,
required: true,
},
to: {
type: Date,
},
current: {
type: Boolean,
default: false,
},
description: {
type: String,
maxlength: 500,
trim: true,
},
},
],
social: {
youtube: {
type: String,
maxlength: 100,
trim: true,
},
twitter: {
type: String,
maxlength: 100,
trim: true,
},
facebook: {
type: String,
maxlength: 100,
trim: true,
},
linkedin: {
type: String,
maxlength: 100,
trim: true,
},
instagram: {
type: String,
maxlength: 100,
trim: true,
},
},
date: {
type: Date,
default: Date.now,
},
});
export default model('profile', profileSchema);
我已经在单个文件中创建了此模型,它似乎太大了。因此,我应该将经验,教育和社交分为三个独立的模型吗?如果是这样,我该怎么办?如果将它们放入3个单独的模型中,如何将它们与配置文件模型链接?一个例子将受到高度重视。
回答如下:是的,您应该将它们分开。要链接它们,您只需将概要文件架构ID放在其他模型上的字段中即可。
const profileSchema = new Schema({
userId: Schema.Types.ObjectId
})
const experienceSchema = new Schema({
userId: Schema.Types.ObjectId
})
const educationSchema = new Schema({
userId: Schema.Types.ObjectId
})
然后,您只需按userId
来查询体验集合以获取他们的体验。这是我推荐的方式。
另一种方法是将experienceIds
放在引用体验模型的配置文件架构上,并可以使用populate
方法填充字段。
