ZF2 - shared models between modules - php

In current state I've got two modules - main module, and admin panel module.
Main module is called "Kreator", admin -> "KreatorAdmin". All the models are located inside the Kreator module (Kreator/Model/UserTable.php etc.).
"KreatorAdmin" is almost empty, there is a configuration for it:
KreatorAdmin/config/module.config.php
<?php
return array(
'controllers' => array(
'invokables' => array(
'KreatorAdmin\Controller\Admin' => 'KreatorAdmin\Controller\AdminController',
),
),
'router' => array(
'routes' => array(
'zfcadmin' => array(
'options' => array(
'defaults' => array(
'controller' => 'KreatorAdmin\Controller\Admin',
'action' => 'index',
),
),
),
),
),
'view_manager' => array(
'template_path_stack' => array(
__DIR__ . '/../view'
),
),
);
KreatorAdmin/src/KreatorAdmin/AdminController.php
<?php
namespace KreatorAdmin\Controller;
use Zend\Mvc\Controller\AbstractActionController;
use Zend\View\Model\ViewModel;
class AdminController extends AbstractActionController
{
public function indexAction()
{
//$this->getServiceLocator()->get('Kreator\Model\UserTable');
return new ViewModel();
}
}
KreatorAdmin/Module.php
<?php
namespace KreatorAdmin;
class Module
{
public function getConfig()
{
return include __DIR__ . '/config/module.config.php';
}
public function getAutoloaderConfig()
{
return array(
'Zend\Loader\StandardAutoloader' => array(
'namespaces' => array(
__NAMESPACE__ => __DIR__ . '/src/' . __NAMESPACE__,
),
),
);
}
}
Simply adding "use" statements in controller and navigating by namespaces results in error
Argument 1 passed to KreatorAdmin\Controller\AdminController::__construct() must be an instance of Kreator\Model\UserTable, none given,
I also tried to play a bit with service manager as described here:
ZF2 Models shared between Modules but no luck so far.
How am I supposed to access UserTable from KreatorAdmin/src/KreatorAdmin/AdminController.php ?
Cheers!
update 1
I've added getServiceConfig to Module.php
public function getServiceConfig()
{
return [
'factories' => [
// 'Kreator\Model\UserTable' => function($sm) {
// $tableGateway = $sm->get('UserTableGateway');
// $table = new UserTable($tableGateway);
// return $table;
// },
// 'UserTableGateway' => function($sm) {
// $dbAdapter = $sm->get('Zend\Db\Adapter\Adapter');
// $resultSetPrototype = new ResultSet();
// $resultSetPrototype->setArrayObjectPrototype(new User());
// return new TableGateway('user', $dbAdapter, null, $resultSetPrototype);
// },
'DbAdapter' => function (ServiceManager $sm) {
$config = $sm->get('Config');
return new Adapter($config['db']);
},
'UserTable' => function (ServiceManager $sm) {
return new UserTable($sm->get('UserTableGateway'));
},
'UserTableGateway' => function (ServiceManager $sm) {
$dbAdapter = $sm->get('DbAdapter');
$resultSetPrototype = new ResultSet();
$resultSetPrototype->setArrayObjectPrototype(new User());
return new TableGateway('users', $dbAdapter, null, $resultSetPrototype);
},
],
];
}
And updated controller
class AdminController extends AbstractActionController
{
protected $userTable;
public function indexAction()
{
$userTable = $this->getServiceLocator()->get('Kreator\Model\UserTable');
return new ViewModel();
}
}
First error - using commented version:
Zend\ServiceManager\Exception\ServiceNotFoundException: Zend\ServiceManager\ServiceManager::get was unable to fetch or create an instance for Zend\Db\Adapter\Adapter
Second - using uncommented part:
Zend\ServiceManager\Exception\ServiceNotFoundException: Zend\ServiceManager\ServiceManager::get was unable to fetch or create an instance for Kreator\Model\UserTable
Solution
If anyone wonder. Using above configuration there is a correct solution in jobaer answer.
Using commented version, you have to remember to add
'Zend\Db\Adapter\Adapter' => 'Zend\Db\Adapter\AdapterServiceFactory',
somewhere in config to service_manager.

May be you messed up with ZF2 and ZF3 configuration. I am not sure but somewhere may be, you tried to create a factory of AdminController by passing an instance of UserTable to make it available inside AdminController's action methods. And later you are not passing that instance of UserTable into the AdminController's constructor while working with it further. The highlighted part from the previous line results in that error.
In ZF2 you do not need to pass that UserTable instance in the controller's constructor for its availability. Just use the following one in any controller's action methods.
$userTable = $this->getServiceLocator()->get('UserTable');
If want to know how this process is done, please, refer to this part of the tutorial.

Plugins not working in controller

I'm building my first Zend Framework 2 application with the skeleton tutorial. But whenever I try to call any plugin from any controller, I get the error message:
A plugin by the name "PLUGIN_NAME" was not found in the plugin manager

Unfortunately I don't know which part of the code could help you to help me. I post some files which I think could be important.

I'm trying to call my plugins like this from a controller action:
$this->flashMessanger()->...
$this->identity();
$this->getServiceLocator();
Because I really needed the Service Locator, I found a workaround, which is not so nice I think, but works for me:
$sm = $this->getEvent()->getApplication()->getServiceManager();
But I guess something is wrong here.
Edit:
For a better reproduction of what I did (I installed Zend Framework again and it still gives me the same error):
Installed Zend Framework (2.4 I guess?) by this installation guide (https://framework.zend.com/manual/2.4/en/ref/installation.html). I installed it with the following command:
composer create-project -sdev --repository-url="https://packages.zendframework.com" zendframework/skeleton-application
On the installation, when I was asked if I want to install a minimum install, I chose "No". Every next question I answered with "Yes" (the installer asks to install a lot of modules, I installed them all).
The installer asked in which config I want to inject "ZendDeveloperTools". I answered 2 (config/development.config.php.dist). For all others I chose 1 (config/modules.config.php).
I tested the skeleton application by calling the url in my browser, it worked.
I downloaded the Album module from GitHub here (https://github.com/Hounddog/Album).
I copied the album module to my modules folder.
I added the entry 'Album' to my config/modules.config.php file
I browsed to the album page
I'm getting the error:
A plugin by the name "getServiceLocator" was not found in the plugin
manager Zend\Mvc\Controller\PluginManager
I assume the reason for this error is the getAlbumTable() method in the AlbumController
public function getAlbumTable()
{
if (!$this->albumTable) {
$sm = $this->getServiceLocator();
$this->albumTable = $sm->get('Album\Model\AlbumTable');
}
return $this->albumTable;
}
In the ZF2 docs for controller plugins you can read that your controller has to implement the following methods: setPluginManager, getPluginManager and plugin. You can also read:
For an extra layer of convenience, both AbstractActionController and AbstractActionController have __call() implementations that allow you to retrieve plugins via method calls:
$plugin = $this->url();
Does your controller extend AbstractActionController or AbstractActionController? If yes, it should work as mentioned in the docs (so those methods you mention in your question should work).
Since you didn't share any controller code it is hard to say whether this is the problem...
UPDATE
The error you get is not related to the configuration of your ControllerPluginManager, but you get this error because you are doing:
$sm = $this->getServiceLocator();
Since the method getServiceLocator doesn't exist the magic __call() method is executed and this leads to the error.
This is because in the latest versions of ZF2 the controller classes are no longer 'service locator aware' meaning you cannot retrieve the ServiceManager by calling $this->getServiceLocator().
Instead you will have to inject your Album\Model\AlbumTable service into the controller class inside a factory:
1) Add a constructor method to your controller class:
public function __construct(AlbumTable $albumTable){
$this->albumTable = $albumTable;
}
2) Create a factory for your controller:
<?php
namespace Album\Controller\Factory;
use Album\Controller\AlbumController;
class AlbumControllerFactory implements FactoryInterface
{
/**
* #param ServiceLocatorInterface $serviceLocator
* #return AlbumController
*/
public function createService(ServiceLocatorInterface $serviceLocator)
{
$controllerPluginManager = $serviceLocator;
$serviceManager = $controllerPluginManager->get('ServiceManager');
$albumTable = $serviceManager->get('Album\Model\AlbumTable');
return new AlbumController($albumTable);
}
}
3) Register your controller factory inside your module.config.php:
'factories' => [
`Album\Controller\AlbumController` => `Album\Controller\Factory\AlbumControllerFactory`,
],
The function getAlbumTable() was used in ZF2 tutorial but in ZF3 it was replaced by member table.
Change the deleteAction() function in AlbumController.php to read:
public function deleteAction()
{
$id = (int) $this->params()->fromRoute('id', 0);
if (!$id) {
return $this->redirect()->toRoute('album');
}
$request = $this->getRequest();
if ($request->isPost()) {
$del = $request->getPost('del', 'No');
if ($del == 'Yes') {
$id = (int) $request->getPost('id');
$this->table->deleteAlbum($id);
}
// Redirect to list of albums
return $this->redirect()->toRoute('album');
}
return array(
'id' => $id,
'album' => $this->table->getAlbum($id)
);
}
Note the two lines reading $this->table->... instead of $this->getAlbumTable()->...

how to solve this error?
please give me the solution,zend is looking so tough i m trying to learn zend from 2 weeks bt this error is just eating my mind.
please help guyz
Make sure your namespaces are set up correctly. Your Album class has to be in the Album namespace if you're calling it like you are. Otherwise use the fully qualified name.

Module getServiceConfig not injecting TableGateway into repository

I can't seem to get my table gateway to inject into my repository(service)...
I have the following:
Module.php:
public function getConfig()
{
return include __DIR__ . '/config/module.config.php';
}
public function getServiceConfig()
{
return array(
'factories' => array(
'Album\Model\Concrete\AlbumRepository' => function($sm) {
$tableGateway = $sm->get('AlbumTableGateway');
$table = new AlbumRepository($tableGateway);
return $table;
},
'AlbumTableGateway' => function ($sm) {
$dbAdapter = $sm->get('Zend\Db\Adapter\Adapter');
$resultSetPrototype = new ResultSet();
$resultSetPrototype->setArrayObjectPrototype(new Album());
return new TableGateway('albums', $dbAdapter, null, $resultSetPrototype);
}
)
);
}
and here is my module.config.php:
return array(
'service_manager' => array(
'invokables' => array(
'Album\Model\Abstracts\IAlbumRepository' => 'Album\Model\Concrete\AlbumRepository'
),
),
'controllers' => array(
'factories' => array(
'Album\Controller\Album' => 'Album\Model\Factories\AlbumControllerFactory',
),
),
the error is:
Catchable fatal error: Argument 1 passed to Album\Model\Concrete\AlbumRepository::__construct() must be an instance of Zend\Db\TableGateway\TableGateway, none given, called in C:\xampp\htdocs\ZendFrameworkTest\vendor\zendframework\zendframework\library\Zend\ServiceManager\ServiceManager.php on line 1035 and defined in C:\xampp\htdocs\ZendFrameworkTest\module\Album\src\Album\Model\Concrete\AlbumRepository.php on line 11
Note:
the delegate functions on the factories array are just not getting called, i'm doing somethign silly but i can't tell what.
I'm also doing dependancy injection, i'm guessing this is where it's going wrong as the factory is creating the repository object without the injection:
class AlbumControllerFactory implements FactoryInterface
{
/**
* Create service
*
* #param ServiceLocatorInterface $serviceLocator
*
* #return mixed
*/
public function createService(ServiceLocatorInterface $serviceLocator)
{
// Need to do something here?
$realServiceLocator = $serviceLocator->getServiceLocator();
$postService = $realServiceLocator->get('Album\Model\Abstracts\IAlbumRepository');
return new AlbumController($postService);
}
}
You defined your repository as invokable, that means that service manager tries to create it by instantiating directly without any params.
change it to alias
return array(
'service_manager' => array(
'aliases' => array(
'Album\Model\Abstracts\IAlbumRepository' => 'Album\Model\Concrete\AlbumRepository'
),
),
);

zend framework 2 AuthenticationService

I have two controllers in my Module and both of them need to see if the user is logged in or not. The Login controllers authenticates the user using DbTable and writes the identity into the storage.
I am using >Zend\Authentication\AuthenticationService; $auth = new AuthenticationService();
inside the controller function but then i instantiate its instance on multiple pageAction()
for this i wrote a function into the Module.php
as follows
public function getServiceConfig()
{
return array(
'factories' => array(
'Application\Config\DbAdapter' => function ($sm) {
$dbAdapter = $sm->get('Zend\Db\Adapter\Adapter');
return $dbAdapter;
},
'Admin\Model\PagesTable' => function($sm){
$dbAdapter = $sm->get('Zend\Db\Adapter\Adapter');
$pagesTable = new PagesTable(new TableGateway('pages',$dbAdapter) );
return $pagesTable;
},
'Admin\Authentication\Service' => function($sm){
return new AuthenticationService();
}
),
);
}
As you can see i am returning new AuthenticationService() every time which i think is bad. I could not find how to grab the already instantiated instance of the service or
i have to write a singleton class for this. Please advise any sample code snipets with deeper explaination would be highly regarded and appreciated thanks.
Try this instead:
public function getServiceConfig()
{
return array(
'aliases' => array(
'Application\Config\DbAdapter' => 'Zend\Db\Adapter\Adapter',
'Admin\Authentication\Service' => 'Zend\Authentication\AuthenticationService',
),
'factories' => array(
'Admin\Model\PagesTable' => function ($serviceManager) {
$dbAdapter = $serviceManager->get('Application\Config\DbAdapter');
$tableGateway = new TableGateway('pages', $dbAdapter);
$pagesTable = new PagesTable($tableGateway);
return $pagesTable;
},
),
);
}
Note mainly the 'aliases' section of the root array, any other changes are just cosmetic and you may prefer to do the original way you suggested (such as using a factory to retrieve the Zend\Db\Adapter\Adapter instance instead of aliasing that too).
Kind Regards,
ise

Zend 2: Model table from view helper error

I'm having a problem with setting up a model table from a view helper. I have used the exact same code that I use within my regular controllers: e.g.:
namespace Application\View\Helper;
use Zend\View\Helper\AbstractHelper;
use Application\Model\MenusTable;
use Zend\ServiceManager\ServiceLocatorAwareInterface;
use Zend\ServiceManager\ServiceLocatorInterface;
**snipped**
public function setServiceLocator(ServiceLocatorInterface $serviceLocator)
{
$this->serviceLocator = $serviceLocator;
return $this;
}
public function getServiceLocator()
{
return $this->serviceLocator;
}
public function getMenusTable()
{
if (!$this->menusTable) {
$sm = $this->getServiceLocator();
$this->menusTable = $sm->get('Application\Model\MenusTable');
}
return $this->menusTable;
}
public function allLinks()
{
$all = $this->getMenusTable()->fetchAll();
return $all;
}
However I am met with this error:
Catchable fatal error: Argument 1 passed to Application\Model\MenusTable::__construct() must be an instance of Zend\Db\Adapter\Adapter, none given, called in C:\xampp\**snipped**\zend\library\Zend\ServiceManager\AbstractPluginManager.php on line 177 and defined in C:\xampp\**snipped**\Application\src\Application\Model\MenusTable.php on line 14
Everything works fine from the main controllers, but here I seem to hit a big problem - I'm new to Zend, but it appears to not be getting the factory from the Module.php file - is there any way to get it?
I have this in my Module.php - as said it works fine in a regular controller, but in a view helper it's not processed for some reason:
public function getServiceConfig()
{
return array
(
'factories' => array
(
'Application\Model\MenusTable' => function($sm)
{
$dbAdapter = $sm->get('Zend\Db\Adapter\Adapter');
$table = new MenusTable($dbAdapter);
return $table;
},
),
);
}
After re-reading your question I realized that your using ZF2.
here is a tutorial on using ServiceLocators http://framework.zend.com/wiki/display/ZFDEV2/Proposal+for+ServiceLocator+and+DependencyInjector
From the Documentation you need to define your DB connection.
$services = new ServiceLocator();
// Registering an object:
$services->set('db', $db);
// Lazy-loading by registering a closure:
$services->set('db', function() use ($config) {
$db = Db::factory($config->db);
return $db;
});
// Retrieving:
$db = $services->get('db');
First you should use the getServiceConfig() in your module ::
public function getServiceConfig()
{
return array(
'factories' => array(
'MODULE\Model\MenusTable' => function($sm) {
$tableGateway = $sm->get('MenusTableGateway');
$table = new MenusTable($tableGateway);
return $table;
},
'MenusTableGateway' => function ($sm) {
$dbAdapter = $sm->get('Zend\Db\Adapter\Adapter');
$resultSetPrototype = new ResultSet();
$resultSetPrototype->setArrayObjectPrototype(new Menus());
return new TableGateway('menus', $dbAdapter, null, $resultSetPrototype);
},
),
);
}
THE ADAPTER might be in your /config/autoload/global.php, like this :
'service_manager' => array(
'factories' => array(
'Zend\Db\Adapter\Adapter' => 'Zend\Db\Adapter\AdapterServiceFactory',
),
),
// CONNECTION DB
'db' => array(
'driver' => 'Pdo',
'dsn' => 'mysql:dbname=YOURDBNAME;host=localhost',
'username' => 'root',
'password' => '',
'driver_options' => array(
PDO::MYSQL_ATTR_INIT_COMMAND => 'SET NAMES \'UTF8\''
),
),
Next your View helper must extend AbstractHelper but also implement ServiceLocatorAwareInterface
class MyViewHelper extends AbstractHelper implements ServiceLocatorAwareInterface
I'll put the code in my website
