Issue with hasMany. Associated entities do not persist. #102

Description

@olivierntk

Trying to persist an object with its child associated entities via a hasMany relationship.

Here is the snippet:

'use strict';

var persist = require('persist');
var type = persist.type;

// define some model objects

var Employee = persist.define('Employee', {
  'id': {
    'type': type.INTEGER,
    'dbColumnName': 'ID',
    'primaryKey': true
  },
  'name': {
    'dbColumnName': 'NAME',
    'type': type.STRING
  },
  'ssn': {
    'dbColumnName': 'SSN',
    'type': type.STRING
  },
  'companyId': {
    'dbColumnName': 'COMPANY_ID',
    'type': type.INTEGER
  }
});

var Company = persist.define('Company', {
  'id': {
    'type': type.INTEGER,
    'dbColumnName': 'ID',
    'primaryKey': true
  },
  'name': {
    'dbColumnName': 'NAME',
    'type': type.STRING
  }
}).hasMany(Employee);


var employee1 = new Employee({'name':'Joe Smith', 'ssn': '123-11-1234'});
var employee2 = new Employee({'name':'Marc Grant', 'ssn': '123-11-0000'});
var company1 = new Company({'name': 'intuit', employees: [employee1, employee2]});

persist.connect(function(err, connection) {
  company1.save(connection, function(err) {
    console.log(err);
  });
});

In the examples, the foreign key isn't usually declared. But since in the db, the foreign key name is called 'COMPANY_ID', I added a companyId property in the Employee model.

Not sure what I am doing wrong here. Any help would be appreciated.

Also, the trace tells me an INSERT stmt was run against the companies table but not against the Employees table.
