AppModel.php

<?php
App::uses('Model', 'Model');
class AppModel extends Model {
  public $findMethods = array('noModelName' =>  true);
  protected function _findNoModelName($state, $query, $results = array()) {
    if ($state == 'before') {

    } elseif ($state == 'after') {
      $modelNameKey = $this->name.'.';
      $resultsNoModelName = array();
      $flatResult = Hash::flatten($results);
      foreach ($flatResult as $key => $value){
        $key = str_ireplace($modelNameKey, '', $key);
        $resultsNoModelName[ $key ] = $value;
      }
      return Hash::expand($resultsNoModelName);
