i am trying to add multiple users on a atlas mongoDB - node.js

Question

I have created a rest api and I am trying to add multiple users to atlas mongodb I use this schema
const mongoose = require('mongoose');
const { v1: uuidv1 } = require('uuid');
const crypto = require('crypto')
const userSchema = new mongoose.Schema({
// _id: mongoose.Types.ObjectId,
name: {
type: String,
// trim: true,
unique: true,
required: true,
index: true
},
email: {
type: String,
// trim: true,
required: true,
unique: true,
},
hashed_password: {
type: String,
trim: true,
required: true
},
salt: String,
created: {
type: Date,
default: Date.now
},
updated: Date,
})
// VIRTUAL FIELD
userSchema.virtual('password')
.set(function(password){
//create temporary variable called _password
this._password = password
//generate a timestamp
this.salt = uuidv1();
//encryptPassword
this.hashed_password = this.encryptPassword(password)
})
.get(function(){
return this._password
})
///methods
userSchema.methods = {
authenticate: function(plainText){
return this.encryptPassword(plainText) === this.hashed_password
},
encryptPassword : function(password){
if(!password) return "";
try{
return crypto.createHmac('sha256', this.salt)
.update(password)
.digest('hex');
} catch(err){
return ""
}
}
}
module.exports = mongoose.model('User', userSchema);
I use this function to sign up :
exports.signup = async (req, res) => {
const userExists = await User.findOne({email : req.body.email})
if(userExists) return res.status(403).json({
error: "EMAIL is TAKEN"
})
const user = await new User(req.body)
await user.save()
.then(result => {res.json({result: result})})
.catch(err => res.json({err : err}))
}
I validate :
exports.userSignupValidator = (req, res, next) => {
//name is not null and its between 4 and 10 characters
req.check('name', 'name is required').notEmpty();
//email is not null, valid and NORMALIZED -> we will use method chaining
req.check('email', 'please enter valid email')
.matches(/.+\#.+\..+/)
.withMessage('email must contain #')
.isLength({
min: 4,
max: 2000
})
//check for password
req.check('password', 'Password is required').notEmpty();
req.check('password').isLength({
min: 6,
}).withMessage('password must be minimum 6 char long').matches(/\d/).withMessage('must contain a number')
//check for errors
const error = req.validationErrors()
////////if error apears show the first one as they appear
if(error){
const firstError = error.map((error) => error.msg)[0]
return res.status(400).json({error: firstError})
}
////proceed to next middleware
next()
}
and I use the route :
const express = require('express'); //bring in express
const postController = require('../controlers/postControler') //brings everything that is exported from the postControler FILE and becomes a OBJECT
const router = express.Router();
const validator = require('../validator');
const signup = require('../controlers/authControler');
const userById = require('../controlers/userControler');
router.get('/', postController.getPosts)
router.post('/post', signup.requireSignIn, validator.createPostValidator, postController.createPost)
router.get('/test' , postController.test)
router.post('/signup', validator.userSignupValidator, signup.signup)
router.post('/signin', signup.signin)
router.get('/signout', signup.signout)
router.get('/lahoha', userById.getUsers)
////find the user by id with params
////any routes containing :userId our app will first execute userById()
router.param('userId', userById.userById);
///////////////////////////////////////////////
module.exports = router
the problem is when I try to create a second user with postman with :
{
"name": "petru",
"email": "petru#gmail.com",
"password": "notazece10"
}
I get the error :
{
"err": {
"driver": true,
"name": "MongoError",
"index": 0,
"code": 11000,
"keyPattern": {
"username": 1
},
"keyValue": {
"username": null
}
}
}
Please help !!!!! this error is driving me crazy, I don't know what I'm doing wrong

Answer 1

after running thru my code multiple times line by line i found out the code is fine , the problem was in my atlas mongodb database.
So i am new to nodejs and mongo , and i try to learn , when i created my first mongodb database in atlas i did not pay attention to naming my database so it had the default name of .
I went back to atlas mongodb and i made a new database ( cluster) , named it TEST , copied the link, went into my dotenv file paste the link to my MONGO_URI restarted the server and then all code worked fine now i can add as many users as i want.
I hope other newcomers to mongodb and nodejs learn from my mistake and if someone ever repeats my STUPID mistake i hope they find this and fix it.
