Models could not be loaded.

Have been experiencing diffulty loading the models. This is a two part question. Is there a way to ramp up the verbosity of the errors. The model errors are very generic and don't give the same pinpoint accuracy we get just using PHP.

[Sun May 17 08:19:33.508702 2015] [:error] [pid 10568] [client XXXX.XXX.XXX.XXX:51994] PHP Fatal error:  Uncaught exception 'Phalcon\\Mvc\\Model\\Exception' with message 'Model 'organisation' could not be loaded' in /var/www/xxxx/xxxx/index.php:12\nStack trace:\n#0 [internal function]: Phalcon\\Mvc\\Model\\Manager->load('organisation', true)\n#1 [internal function]: Phalcon\\Mvc\\Model\\Query->_prepareSelect()\n#2 [internal function]: Phalcon\\Mvc\\Model\\Query->parse()\n#3 [internal function]: Phalcon\\Mvc\\Model\\Query->execute(NULL, NULL)\n#4 /var/www/xxxx/xxxx/index.php(12): Phalcon\\Mvc\\Model\\Manager->executeQuery('SELECT * FROM o...')\n#5 [internal function]: {closure}()\n#6 /var/www/xxxx/xxxx/index.php(84): Phalcon\\Mvc\\Micro->handle()\n#7 {main}\n  thrown in /var/www/xxxx/xxxx/index.php on line 12

The Model File content is:

use Phalcon\Mvc\Model,
    Phalcon\Mvc\Model\Query;
use Phalcon\Loader;
use Phalcon\Mvc\Micro;
use Phalcon\DI\FactoryDefault;
use Phalcon\Db\Adapter\Pdo\Mysql as PdoMysql;

$di = new FactoryDefault();

//Set up the database service
$di->set('db', function(){
    return new PdoMysql(array(
        "host"      => "######",
        "username"  => "#####",
        "password"  => "######",
        "dbname"    => "######"
    ));
});

//Create and bind the DI to the application
$app = new Micro($di);

class organisation extends Model
{
    public function getSource()
    {
        return 'sav1_organisations';
    }

    public function get_organisations($options = array())
    {
        $sql  = "SELECT * ";
        $sql .= "FROM sav1_organisations";

        $query = new Query($sql, $this->getDI());
        return $query->execute();

    }
}

// Use Loader() to autoload our model
$loader = new Loader();

$loader->registerDirs(array(
    __DIR__ . '/models/'
))->register();

called using:

//Retrieves all organisations
$app->get('/api/organisation', function() use ($app) {

    $phql = "SELECT * FROM organisation ORDER BY orgName";
    $organisation = $app->modelsManager->executeQuery($phql);

    $data = array();
    foreach ($organisation as $org) {
        $data[] = array(
            'id'    => $org->id,
            'name'  => $org->orgName,
        );
    }

    echo json_encode($data);

});

not sure where where the error is because the response from the server does not give enough detail (is it the password, namespace etc.)

Sorry to be a pain. Still learning. Hopefully this will be all for today :)
