Class Users not found in Phalcon 2 - php

Question

So basically I just installed Phalcon 2.0 on my ubuntu machine, with apache2, mysql and all the stuff installed. I went straight into the documentation of Phalcon to get me started. After following the exact steps from their tutorial, I got this error:
Fatal error: Class 'Users' not found in /var/www/html/phalcon/tutorial/app/controllers/SignupController.php on line 14
I think it may be related to namespacing of classes and stuff like that, but I wasn't able to figure it out so far.

Answer 1

Looks like you didn't register your folders properly. I add a resume of my code to give you an idea.
File index.php
use Phalcon\Mvc\Micro;
use Phalcon\Events\Manager as EventsManager;
define('APP_DIR', dirname(__DIR__) .'/');
try {
$config = require APP_DIR .'config/config.php';
require APP_DIR .'config/loader.php';
...
} catch (Exception $e) {}
File config.php
return new Phalcon\Config([
'application' => [
'environment' => 'development',
'controllers' => APP_DIR .'controllers/',
'library' => APP_DIR .'library/',
'models' => APP_DIR .'models/',
'plugins' => APP_DIR .'plugins/',
'routes' => APP_DIR .'routes/',
'logs' => APP_DIR .'logs/',
'base_uri' => '/',
'debug' => false
]
]);
File loader.php
<?php
$loader = new \Phalcon\Loader;
// Register directories
$loader->registerDirs([
$config->application->controllers,
$config->application->library,
$config->application->models,
$config->application->plugins,
])->register();
// Composer autoloader
require_once APP_DIR .'vendor/autoload.php';
This should resolve any class specified in config folders.
