Mongodb和Node js

Question

我是节点js的新手，我正在尝试使用节点js和mongo DB构建一个app测验引擎。我不确定我需要为测验引擎制作模式。所以任何人都可以帮助我。

Answer 1

以下是用户架构的示例...

var userSchema = new Schema({

    name: {
        type: String,
        unique: true,
        required: true
    },
    password: {
        type: String,
        required: true
    }
});

但就像评论所说的那样，你必须更加具体。

Answer 2

据我所知，测验将由用户提供，它将有问题。所以，你可以制作两个实体：

i）用户实体ii）测验/问题实体

用户实体架构：

module.exports = {
   attributes = {
     name: {
        type: String,
        required: true
    },
    password: {
        type: String,
        required: true
    }
    password: {
        type: String,
        required: true
    }
  }
};

问题实体架构：

module.exports = {
   attributes = {
     questionLabel: {
        type: 'String',
        required: true
    },
    choices: {
        type: 'Array',
        required: true
    }
  };

Answer 3

你好，这是我的架构

enter code here var mongoose = require("mongoose");
var Schema = mongoose.Schema;

var img_schema = new Schema({
    title:{type:String,require:true},
    creator:{type:Schema.Types.ObjectId, ref: "User" },
    extension:{type:String,require:true},
    foto:{type:String,require:true},
    uso:{type:String,require:true}
 });

var Imagen = mongoose.model("Imagen",img_schema);
 module.exports = Imagen;

Answer 4

This is the example of user schema. you can replace with your requirement.

// User Schema
var UserSchema = mongoose.Schema({
    username: {
        type: String,
        index: true
    },
    password: {
        type: String
    },
    email: {
        type: String
    },
    name: {
        type: String
    },
    profileimage:{
        type: String
    }
});

var User = module.exports = mongoose.model('User', UserSchema);

Answer 5

我建议你使用mongoose来定义你的mongoDB集合模式。 Mongoose促进了nodejs和mongoDB之间的许多进程。您可以使用以下命令安装mongoose：

npm i mongoose

然后创建一个这样的架构：

import mongoose from 'mongoose';
const { Schema } = mongoose; //Pulling schema out of mongoose object

const QuizEngineSchema = new Schema({
 name: String,
 phoneNumber: Number,
 // other data that you need to save in your model
},
{timestamps: true},
{id: false});

//Plugging the Schema into the model
const QuizEngine = mongoose.Model('QuizEngine',QuizEngineSchema);

export default QuizEngine;

希望这可以帮助！
