Properties with default values in Mongoose schema are not persisting

I have the following schema I've written using Mongoose:

var querySchema = mongoose.Schema({
    quoteId: { type: String, default: '' },
    zipcode: { type: String, default: '' },
    email: { type: String, default: '' },
    type: {type: String, default: ''},
    isEmailChecked: { type: Boolean, default: true },
});

I provide values for only 3 properties in the querySchema assuming that the result of the fields will take default values when a new instance of query object is persisted:

var query = {};
query.quoteId = "1414775421426";
query.email = "[email protected]";
query.type = "Foo";

But following document is what I see as the result in the collection:

{
    "_id" : ObjectId("5453c27d0e4c3f2837071856"),
    "email" : "[email protected]",
    "type" : "Foo",
    "quoteId" : "1414775421426",
    "__v" : 0
}

Should isEmailChecked and zipcode not be assigned their default values when a new instance of query object is persisted to the MongoDB database?

Following is how I am persisting an instance of the query object using ExpressJS/NodeJS:

app.post('/api/queries', function (req, res) {
    QuoteQuery.create({
        quoteId: req.body.query.quoteId,
        type: req.body.query.type,
        zipcode: req.body.query.zipcode,
        email: req.body.query.email,
        isEmailChecked: req.body.query.isEmailChecked,
    }, function (err, query) {
        if (err) {
            res.send(err);
        }
        res.json(query);
    });
});

Could somebody help me understand that why I got the isEmailChecked and zipcode properties in the resulting document in the MongoDB database?

I am using NodeJS, AngularJS and ExpressJS in my application along with MongoDB.

When you set mongoose model field it not use default value.

As workaround you can use underscore to extend mongoose model object with keys which exists in your query object like this:

_.extend(dbQueryObject, query);

Here is complete example: 

var mongoose = require('mongoose');

var querySchema = mongoose.Schema({
  quoteId: { type: String, default: '' },
  zipcode: { type: String, default: '' },
  email: { type: String, default: '' },
  type: {type: String, default: ''},
  isEmailChecked: { type: Boolean, default: true }
});

var db = mongoose.createConnection('mongodb://localhost:27017/stackoverflow',
  { server: { auto_reconnect: true } },
  function(err) {
    var QuerySchema = db.model('test', querySchema);

    var query = {};
    query.quoteId = "1414775421426";
    query.email = "[email protected]";
    query.type = "Foo";

    QuerySchema.create({
      quoteId: query.quoteId,
      type: query.type,
      zipcode: query.zipcode,
      email: query.email,
      isEmailChecked: query.isEmailChecked
    }, function (err, query) {
      process.exit(0);
    });
  });

Here is what in db:

{
    "_id" : ObjectId("5453ce3c9f7e0d13c52abf61"),
    "type" : "Foo",
    "email" : "[email protected]",
    "quoteId" : "1414775421426",
    "__v" : 0
}
