Newly entered field does not inserted in already created collection after updating mongoose schema

I have already created one MongoDB collection using mongoose schema from express web service after some days I found a requirement of a new field in mongoose table so added that field in mongoose schema and try to insert a value of newly added field along with existing fields but it's not get inserted in the newly added document.

So what I have done as a troubleshooting process, I deleted my existing collection totally and then inserted my new document in a collection, Then I found It started working properly. My newly inserted field get inserted into the collection. So Is there any other way to add a new field in MongoDB using mongoose without deleting the whole collection.

My existing user collection schema:

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

var userSchema = new Schema({
  username: { type: String, required: true, unique: true },
  password: { type: String, required: true },
});

var User = mongoose.model('User', userSchema);

module.exports = User;

When I inserted a new document with username and password In above collection It works fine.

My new user collection schema after adding new field (name):

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

var userSchema = new Schema({
  name: String,
  username: { type: String, required: true, unique: true },
  password: { type: String, required: true },
});

var User = mongoose.model('User', userSchema);

module.exports = User;

But After updating my user schema When I inserted a new document with name, username and password In above collection only insert username and password, name field does not get inserted.

Just do one simple step, add default values to every field you create. Example

var userSchema = new Schema({
  name: {type: String , default: ""},
  username: { type: String, required: true, unique: true },
  password: { type: String, required: true },
});

Happy Coding

Name should be also be an object in the schema like so

var userSchema = new Schema({
  name: {type: String},
  username: { type: String, required: true, unique: true },
  password: { type: String, required: true },
});
