Mongoose relationship

Question

I'm studying Mongodb and I'm using Mongoose and I would like to create a very dynamic registration process. I managed the first step of the registration using Passport and everything works fine, I created the user and it is present on the DB. Now my registration process will continue and user have to select a "role": What kind of user you are? There are 2 options: "basic" and "advanced". Basic has just 3 properties and advanced has the 3 basic properties plus few others.

I need to extend the userSchema or to add new fields based on that role but after a week it doesn't work yet and I tried many NPM like: mongoose-relationship or mongoose-schema-extend.

This is basically what I have:

userSchema = new Schema({
   id           : Number,
   email        : { type: String, required: true },
   role         : { type: String, required: true },
   profile      : { ... } // Profile fields are different for each role.
});

// profile 1
basicSchema = new Schema({
   info1        : { type: String, required: true },
   info2        : { type: String, required: true },
   info3        : { type: String, required: true }
});

// profile 2
advancedSchema = new Schema({
   info1        : { type: String, required: true },
   info2        : { type: String, required: true },
   info3        : { type: String, required: true },
   info4        : { type: String, required: true },
   info5        : { type: String, required: true },
   info6        : { type: String, required: true }
});

The user already exist and he is on a screen where he need to choose a role and populate the chosen profile.

For information I'm using nodejs and expressjs.

I hope you can help. Thanks.

Using mongoose-schema-extend:

Install via npm:$ npm install mongoose-schema-extend

Example using your code:

var mongoose = require('mongoose'),
    extend = require('mongoose-schema-extend');
var Schema = mongoose.Schema;

var userSchema = new Schema({
   id           : Number,
   email        : { type: String, required: true },
   role         : { type: String, required: true },
},{ collection : 'users' });

//profile 1
var basicSchema = userSchema.extend({
   info1        : { type: String, required: true },
   info2        : { type: String, required: true },
   info3        : { type: String, required: true }
});

//profile 2
var advancedSchema = userSchema.extend({
   info1        : { type: String, required: true },
   info2        : { type: String, required: true },
   info3        : { type: String, required: true },
   info4        : { type: String, required: true },
   info5        : { type: String, required: true },
   info6        : { type: String, required: true }
});
