I've stared using Mean stack in a school project, and follow the guide from udemy, Mean stack zero to hero. My problem is when I'm trying to register a user, then this Mongo Error: 11000 comes up.. I've looked through the code again and again, and I can't seem to find the error.

This is my model:
var mongoose = require('mongoose');

var userSchema = new mongoose.Schema({
username: {
type: String,
unique: true,
required: true
password: {
type: String,
required: true
mongoose.model('User', userSchema);

And this i the controller for register:

angular.module('roskildeapp').controller('RegisterController', RegisterController);

function RegisterController($http) { //dolla build in angular
var vm = this;

vm.register = function() {
    var user = {
        username: vm.username,
        password: vm.password

    if (!vm.username || !vm.password) { //if user dosent exist //
        vm.error = 'Tilføj et brugernavn og kodeord.';
    } else {
        if (vm.password !== vm.passwordRepeat) {
            vm.error = 'Kodeordene skal være ens.';
        } else {
            $'api/users/register', user).then(function(result) {
                vm.message = 'Vellykket registering.';
                vm.error = '';
            }).catch(function(error) {

  1. for the duplicate key error, are you registering with the same username or are you clearing your database before reregistering? The username field is unique, so you can't enter the same username twice. The error is pretty clear I think regarding that.

  2. for the validation error regarding the username, can you log the object before it gets created on the server? Or can I at least see a code snippet of how you're creating this on the backend?

Also, it helps if you format your code. Some of your code snippets were formatted, but the rest were incredibly difficult to read. Try wrapping the code in three backticks ```


Sorry, for the mistakes, I've just began coding JavaScript the past few month, and I don't understand all my code, just some parts of it.

  1. Yes, right now my database it empty, well, I cleared it and made a new user, and I couldn't and got the same validation error.

Not sure, but I have my users controller:

@laerkeli how did you clear your database?


I go into mongo in the terminal and then find my db, and then the collection - then I remove all of the users in the database.


Please be a little more detailed in your description, code samples and shell output is helpful. Also, are you sure you're connecting to the same database and using the same collection? Which collection are your users stored in?

I'm pretty sure I'm connected to the right database. I use the collection called "boders" (which have my stalls data) - And I can see the stalls data in my web application and in my database.

I created a user once in my application - and it was stored in the collection called "users", and I could see it in the "users" collection - but I deleted them all, because I couldn't make a new user (and someone told me to try and clear my users).
