# mongoose-population
* Referencing one document from another in MongoDBcan be acheived by using Mongoose population to populate information in a document from a referenced document.
- Use Mongoose population to cross-reference users within a comment
- Populate the comments with the users’ information upon querying
````
var User = new Schema({
username: String,
password: String,
firstname: {
type: String,
default: ''
},
lastname: {
type: String,
default: ''
},
admin: {
type: Boolean,
default: false
}
});
User.methods.getName = function() {
return (this.firstname + ' ' + this.lastname);
};
````
- In the models do the changes to utilize the population
* Comment schema
````
var commentSchema = new Schema({
rating: {
type: Number,
min: 1,
max: 5,
required: true
},
comment: {
type: String,
required: true
},
postedBy: {
type: mongoose.Schema.Types.ObjectId,
ref: 'User'
}
}, {
timestamps: true
});
````
# Updating users.js route
- Open users.js and update the register function as follows:
````
router.post('/register', function(req, res) {
User.register(new User({ username : req.body.username }),
req.body.password, function(err, user) {
if (err) {
return res.status(500).json({err: err});
}
if(req.body.firstname) {
user.firstname = req.body.firstname;
}
if(req.body.lastname) {
user.lastname = req.body.lastname;
}
user.save(function(err,user) {
passport.authenticate('local')(req, res, function () {
return res.status(200).json({status: 'Registration Successful!'}
);
});
});
});
});
````
Save all the changes and start the server and test.
