UPDATE 1: 5 votes have been received, so I have submitted a feature request: https://github.com/LearnBoost/mongoose/issues/2637

Please cast your +1

Answer 1

1. If you are getting a response from REST service and say you have a User mongoose model

var User = mongoose.model('User');
var fields = res.body; //Response JSON
var newUser = new User(fields);
newUser.save(function(err,resource){
  console.log(resource);
});

2. In other case say you have an array of user JSON objects from User.find() that you want to query or populate

var query  = User.find({});
query.exec(function(users){
  //mongoose deep-populate ref docs
  User.deeppopulate users 'email_id phone_number'.exec({
    //query through populated users objects
  });
});

MongoDB doesn't support Joins and Transfers. So for now you can't cast values to an object directly. Although you can work around it with forEach.
