zend framework2 tutorial: Fatal error: Class 'Album\Model\AlbumTable' not found in C:\wamp\www\quickstart\module\Album\Module.php

Question

NOTES: Development is done in Netabean IDE, hosting is local on WAMPP, I have it configured for a virtual host. Composer is being used.

I have reviewed other questions similar to this and I do not have the same issue. Please note this is my first time using Zend framework. Thank you.

The use of echos helped me locate that when I create my AlbumTable in Module.php it fails.

Here is the Stacktrace:

Here is my Album\src\Album\Controller\AlbumController.php

namespace Album\Controller;

use Zend\Mvc\Controller\AbstractActionController;
use Zend\View\Model\ViewModel;

class AlbumController extends AbstractActionController
{
protected $albumTable;

public function indexAction()
{
     return new ViewModel(array(
         'albums' => $this->getAlbumTable()->fetchAll(),
     ));
}

public function getAlbumTable()
{
    echo "Made it";
    if (!$this->albumTable) {
        $sm = $this->getServiceLocator();
        echo "Made it";
        if($sm->has('Album\Model\AlbumTable'))
        {
            echo "FOUND Album\Model\AlbumTable";
            $this->albumTable = $sm->get('Album\Model\AlbumTable');
        }else{
           echo "Could not find Album\Model\AlbumTable";
        }
    }
    echo "Made it";
    return $this->albumTable;
}
}

Here is Album\Module.php

namespace Album;

use Album\Model\Album;
use Album\Model\AlbumTable;
use Zend\ModuleManager\Feature\AutoloaderProviderInterface;
use Zend\ModuleManager\Feature\ConfigProviderInterface;

use Zend\Db\ResultSet\ResultSet;
use Zend\Db\TableGateway\TableGateway;

class Module implements AutoloaderProviderInterface, ConfigProviderInterface
{
    public function getAutoloaderConfig()
    {
    }

    public function getConfig()
    {
        return include __DIR__ . '\config\module.config.php';
    }

    public function getServiceConfig()
    {
        return array(
            'factories' => array(
                'Album\Model\AlbumTable' =>  function($sm) {
                   // echo "inside ftn Album\Model\AlbumTable";
                    $tableGateway = $sm->get('AlbumTableGateway');
                    echo " Gate way GOOD";
                    $table = new AlbumTable($tableGateway);
                    echo "Table good";
                    return $table;
                },
                'AlbumTableGateway' => function ($sm) {
                   // echo "inside ftn AlbumTableGateway";
                    $dbAdapter = $sm->get('Zend\Db\Adapter\Adapter');
                  //  echo "adapater good";
                    $resultSetPrototype = new ResultSet();
                    $resultSetPrototype->setArrayObjectPrototype(new Album());
                    return new TableGateway('album', $dbAdapter, null, $resultSetPrototype);
                },
            ),
        );
     }

}

Here is Album\src\Album\Model\AlbumTable.php

namespace Album\Model;

use Zend\Db\TableGateway\TableGateway;
//use Zend\Db\ResultSet\ResultSet;

class AlbumTable
{
    protected $tableGateway;

    public function __construct(TableGateway $tableGateway)
    {
        echo "inside construct of AlbumTable";
        $this->tableGateway = $tableGateway;
    }

I don't get inside of AlbumTable. I have included it in Module.php with use and the class name and files are spelled correctly. Unless my eyes fail me, and I hope that's the case.

Can anyone tell me why I am getting this error? My out put from the echos are as follows:

Made it Made it FOUND Album\Model\AlbumTable Gate way GOOD

Answer 1

While searching for an answer to my own problem with the in-depth tutorial, I see where in Album\Module.php you wrote the following:

public function getConfig()
    {
        return include __DIR__ . '\config\module.config.php';
    }

When I use those slashes, and reload the index page, I get a blank page. If I change the slashes to match what is indicated in the tutorial, like this:

     return include __DIR__ . '/config/module.config.php';

then the index page loads as expected. You may have other errors, but this much I could test and confirm.

Answer 2

The class cannot be found. If you are not using composer (or some other auto loading means) you will need to return the correct configuration in getAutoloaderConfig to add the module's namespace to the default Zend\Loader\StandardAutoloader.

public function getAutoloaderConfig()
{
    return [
        'Zend\Loader\StandardAutoloader' => [
            'namespaces' => [
                __NAMESPACE__ => __DIR__ . '/src/' . __NAMESPACE__,
            ],
        ],
    ];
}

Answer 3

I had the same problem. In my case, it was because I didn't paste the following line in Module/Album/Module.php:

use Album\Model\Album;

because it wasn't highlighted in yellow in the tutorial.

You need that line!
