從一個文件重用貓鼬現有的架構模型到另一個文件的架構模型

Question

我正在使用兩種不同類型的用戶在Node中構建Web應用程序。 它們兩者將具有共同的以及不同的屬性。 問題是我無法在另一個模型中使用常見的貓鼬模式模型。

user.js是具有以下架構的常見模型：

//Requiring Mongoose
const mongoose = require('mongoose');

//Creating a variable to store our Schemas
const Schema = mongoose.Schema;


//Create User Schema and Model
const UserSchema = new Schema({
    email: {
        type: String,
        required: [true, 'Email Field is required'],
        unique:true,
        match: /[a-z0-9!#$%&'*+/=?^_`{|}~-]+(?:\.[a-z0-9!#$%&'*+/=?^_`{|}~-]+)*@(?:[a-z0-9](?:[a-z0-9-]*[a-z0-9])?\.)+[a-z0-9](?:[a-z0-9-]*[a-z0-9])?/
    },
    name: {
        type: String,
        required: [true, 'Name field is required']
    },
    password: {
        type: String,
        required: [true, 'Please enter your password']
    },
    phoneNo: {
        type: String,
        required: [true, 'Phone No is required']
    }

//Create a user model which is going to represent our model in the database 
   and passing our above-created Schema
    const User = mongoose.model('user', UserSchema);

    //Exporting Models
    module.exports = User;

現在我想在另一個具有其他屬性族的模型文件rider.js中使用相同的UserSchema否我嘗試了以下方法，但失敗了。

 //Requiring Mongoose
const mongoose = require('mongoose');

//Importing user Schema to remove the code redundancy
const userSchema = require('./user');

//Creating a variable to store our Schemas
const Schema = mongoose.Schema;

//Create Driver Schema and Model
const RiderSchema = new Schema({
    user: userSchema
    familyNo: {
        type: String,
        required: [true, 'Name field is required']
    }
});

//Create a rider model is going to represent our model in the database and passing our above-created Schema
const Rider = mongoose.model('rider', RiderSchema);

//Exporting Models
module.exports = Rider;

問題是您沒有傳遞模式，而是傳遞了用戶模型，將userschema移到了不同​​的文件中，並將其用作兩個模型中的模式，這將解決問題。

//Create a user model which is going to represent our model in the database  and passing our above-created Schema
const User = mongoose.model('user', UserSchema);

//Exporting Models
module.exports = User; // Here is the problem, User is a model not schema

UserSchema.js

const UserSchema = mongoose.Schema([Your Common Schema])

user.js的

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

OtherModel.js

var userSchema = require('./UserSchema');
module.exports = mongoose.model('OtherModel' , {
   property : String,
   user : userSchema
});
