WatchMeCode Episode 53 Indexing Difficulty

README

I ran into a problem with unique indexing using Mongoose. Essentially, even though I set the index: {unique: true} flag it still allows duplicate documents.

index.js

var mongoose = require('mongoose'),
		User = require('./user');

mongoose.connect('mongodb://localhost/WatchMeCode', function(err) {
	if (err) { throw err; }

	var user = new User({
		email: "jake@example.com"
	});

	user.save(function(err, user) {
		if (err) { throw err; }

		console.log(user);
		process.exit();
	});
});

user.js

var mongoose = require('mongoose'),
    Schema = mongoose.Schema,
    ObjectId = Schema.ObjectId;

var User;

var UserSchema = new Schema({
  firstName: {type: String},
  lastName: {type: String},
  email: {type: String, required: true, index: {unique: true}},
  password: {type: String}
});

User = mongoose.model('User', UserSchema);

module.exports = User;
