Getting user details in other schema[mongoose] - angularjs

Question

I'm getting my hands on mean stack development. I'm kinda stuck where my requirement is to get posted by functionality. I'm trying to build a simple classified ads app where a user adds/updates/deletes a classified. I'm able to do all of these but now I need to display the name of that particular user on that add who is logged in. I've researched online but couldn't get the solution.
My schema
var UserSchema = new Schema({
username: { type: String, required: true, unique: true },
firstName: { type: String, required: true },
lastName: { type: String, required: true },
email: { type: String, required: true, unique: true, lowercase: true },
phone: { type: Number, min: 10, unique: true },
hash: String,
salt: String
});
var ClassifiedSchema = new Schema({
title: { type: String, required: true, unique: true },
description: { type: String, required: true, },
price: { type: Number, required: true },
created: { type: Date, default: Date.now },
updated: { type: Date, default: null },
contact: {
name: String,
phone: Number,
email: String
},
image: String,
user: { type: mongoose.Schema.Types.ObjectId, ref: 'User' }
});
My route
router.route('/classifieds')
.post(function(req, res) {
var classified = new Classified(req.body);
classified.save(function(err, classified) {
if (err)
res.send(err);
res.json(classified);
});
})
.get(function(req, res) {
Classified.find(function(err, classifieds) {
if (err)
res.send(err);
res.json(classifieds);
});
});
router.route('/register')
.post(function(req, res) {
if (!req.body.username || !req.body.password || !req.body.email || !req.body.firstName || !req.body.lastName) {
return res.status(400).json({message: 'Please fill all the fields!'});
};
var user = new User(req.body);
user.setPassword(req.body.password);
user.save(function(err, user) {
if (err)
res.send(err);
res.json({ token: user.generateJWT()});
});
});
router.route('/login')
.post(function(req, res) {
if (!req.body.username || !req.body.password) {
return res.status(400).json({ message: 'Please fill all the fields!' });
};
passport.authenticate('local', function(err, user, info) {
if (err)
res.send(err);
if (user) {
return res.json({ token: user.generateJWT() });
} else {
return res.status(401).json(info);
};
})(req, res);
});
I want to know how do I get the username while posting the classified? I'm aware of the populate function but I've tried it and it doesn't seem to work.
Update
I've added my register and login route to show you the use of passport.

If you have an authentication system like passport which sets req.user to current logged in user, then:
.get(function(req, res) {
Classified.find({user: req.user},function(err, classifieds) {
if (err)
res.send(err);
res.json(classifieds);
});
});
