[英]Model not saving to MongoDB using mongoose
I am trying to register a user and save the user to MongoDB.我正在尝试注册用户并将用户保存到 MongoDB。 I am creating the user using nodejs
readline
module.我正在使用 nodejs
readline
模块创建用户。 But when I am trying to save it to the mongodb it is not working.但是当我试图将它保存到 mongodb 时它不起作用。 Nor does it is returning any
error
.它也不会返回任何
error
。
Here's the code这是代码
const { Admin, validate } = require('../models/admin');
const mongoose = require('mongoose');
const readline = require('readline');
const rl = readline.createInterface({
input: process.stdin,
output: process.stdout
});
const print_error = '\x1b[31m%s\x1b[0m';
const print_success = '\x1b[32m%s\x1b[0m';
function createUser() {
rl.question('Please Enter Username : ', (username) => {
rl.question('Please Enter a Password : ', async(password) => {
const adminObject = {
username,
password
};
const { error } = validate(adminObject);
if (error) {
rl.close()
rl.removeAllListeners()
return console.log(print_error, error.details[0].message);
}
let admin = await new Admin({
username: username,
password: password
});
console.log(admin);
const result = await admin.save(function(err,res){
if(err){
console.log('err',err);
return console.log('err',err);
}
else return console.log('res', res);
}); // save is not working
console.log(print_success, result);
rl.close(process.exit(1)); // close the process after done saving
});
});
}
createUser();
Admin Model管理模式
const mongoose = require('mongoose');
const Joi = require('joi');
const Admin = new mongoose.model('Admin', new mongoose.Schema({
username: {
type: String,
required: true,
minlength: 1,
maxlength: 10,
unique: true
},
password: {
type: String,
required: true,
minlength:3,
maxlength: 1024
}
}));
function validateAdmin(admin){
const schema = {
username: Joi.string().min(1).required(),
password: Joi.string().min(3).required()
};
return Joi.validate(admin, schema);
}
exports.Admin = Admin;
exports.validate = validateAdmin;
PS - I've connected to the mongodb, the connection is successful. PS - 我已经连接到mongodb,连接成功。
I don't know why you're use
async/await
and then you usefunction
in yoursave
.我不知道你为什么使用
async/await
然后在你的save
使用function
。
You can change your createUser
function with this code below:您可以使用以下代码更改
createUser
函数:
function createUser() {
rl.question('Please Enter Username : ', (username) => {
rl.question('Please Enter a Password : ', async(password) => {
const { error } = validate({ username, password });
if (error) {
rl.close()
rl.removeAllListeners()
return console.log(print_error, error.details[0].message);
}
let admin = new Admin({username, password });
try {
const result = await admin.save();
console.log(print_success, result);
rl.close(process.exit(1));
} catch(ex) {
console.log(ex.message);
}
});
});
}
If you've any problem, then let me know in the comment below.
如果您有任何问题,请在下面的评论中告诉我。
Updated: After test your code, you have no connection in your createUser.js
.更新:测试您的代码后,您的
createUser.js
没有连接。
I've been add this connection below in above of your createUser()
and it's working:我已经在下面的
createUser()
上面添加了这个连接并且它正在工作:
mongoose.connect('mongodb://localhost:27017/url-shortener');
Please, make sure you've add a connection to your
mongodb
.请确保您已添加到
mongodb
的连接。
I hope it can help you.我希望它能帮助你。
