Wrong path to a Pomm map file - postgresql

Question

I'm building a website with Symfony2 and PostgreSQL (for the first time). I've recently discovered the database layer called Pomm, I decided to use it instead of Doctrine2.
However I get a Fatal Error Exception when I try to display some data. The problem might come from a wrong path to the generated Pomm map file. Unfortunately I haven't found any help in the Manual and the tutorials I read to fix my mistake.
Here is what I did:
1- PommBundle Installation into Symfony2.3.1 with Composer = ok
2- Setup (PommBundle registration in the application kernel + database settings) = ok
3- Map file generation for the db table 'product' (as follows) = ok
app/console pomm:mapfile:create product
Pomm generated the folder 'Database' and now the website structure is:
-- Source Files
|-- Database
|-- PublicSchema
|-- Base
ProductMap.php
Product.php
ProductMap.php
|-- app
|-- bin
|-- src
|-- vendor
|-- web
4- app/autoload.php
The PommBundle Documentation about autoload.php is a bit confusing (for a non-native English speaker). Indeed, here's what is written:
If you are using Symfony 2.0.x, you may still be using sf2 autoloader.
Update your app/autoload.php file.
However I'm using Symfony 2.3.1 that's why I thought I don't have to update the app/autoload.php file.
Moreover it's not very clear what you have to add into the file:
# app/autoload.php (original file)
use Doctrine\Common\Annotations\AnnotationRegistry;
use Composer\Autoload\ClassLoader;
$loader = require __DIR__.'/../vendor/autoload.php';
AnnotationRegistry::registerLoader(array($loader, 'loadClass'));
return $loader;
The PommBundle documentation says:
Update your app/autoload.php file [by adding the following code]:
$loader->registerNamespaces(array(
'Symfony' => array(__DIR__.'/../vendor/symfony/src', __DIR__.'/../vendor/bundles'),
...
'Pomm' => __DIR__.'/../vendor/pomm/pomm',
'Pomm\\PommBundle' => __DIR__.'/../vendor/pomm/pomm-bundle',
I didn't understand how I could add this code to my file (shown above). So I guessed this was only for Symfony 2.0.*.
5- Problem in the Controller
In the COntroller I typed the path to the Pomm map file as follows:
namespace Admin\ProductBundle\Controller;
use Symfony\Bundle\FrameworkBundle\Controller\Controller;
class DefaultController extends Controller
{
public function indexAction()
{
$myproducts = $this->get('pomm')
->getDatabase('database')
->createConnection()
->getMapFor('Database\PublicSchema\Product')
->findAll();
return $this->render('AdminProductBundle:Default:index.html.twig',
array("myproducts" => $myproducts));
}
}
I've certainly done something wrong because I get this error:
FatalErrorException: Error: Class 'Database\PublicSchema\ProductMap' not found in
/var/www/mywebsite/vendor/pomm/pomm/Pomm/Connection/Connection.php line 153
I'd be very grateful for any help. Thanks.

Answer 1

The problem is in namespacing.
Symfony trying to call class MyDatabase\PublicSchema\ProductMap that should be located in MyDatabase/PublicSchema/ProductMap.php file whereas your file located in Database/PublicSchema/ProductMap.php
So you should rename the Database folder to MyDatabase ot Database name to Database.
