Example of how to correctly do mongoose GH-228

GH-228.js

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

var db = mongoose.connect('mongodb://localhost/test');

var TestEmbedSchema = new Schema({
    name    :  { type: String, index: true}
});
var TestEmbed = mongoose.model('TestEmbed', TestEmbedSchema);

var TestSchema = new Schema({
    name    :  { type: String, index: true}
  , tesTestEmbeded   :  {
      name: { type: String, index: true }
    }
  , tesTestEmbededarray: [TestEmbedSchema]
});
var Test = mongoose.model('TestSchema', TestSchema);

var test = new Test();
test.name = 'hellomodel';
test.tesTestEmbeded = { name: 'embedded' };

test.save(function(err){
  Test.findOne({name:'hellomodel'}, function(err, item) {
    item.tesTestEmbededarray.push(item.tesTestEmbeded.toObject());
    item.tesTestEmbeded = { name: 'embedded2' };

    item.save(function(err){
      console.log(err);
      console.log(item);
      mongoose.disconnect();
    });
  });
});
