[TYPO3-mvc] How to add a unique/primary key property to a manually created domain model?

[Jan Kornblum]

Hi Henjo,

thanks for spending time to my tries ;)

This is what i would try next as another approach.

> Or - and that's an aproach I am taking in a current project - create an

And maybe this as a third, certainly best approach ;)

Maybe it it not the best example for me when still young with extbase 
;)

First of all i would like to get it work with this approach. But i 
can't figure out my mistake.

Parts from my BasketController:
---

/**
 * The object repository
 * @var \XX\Ext\Service\UserSession
 * @inject
 */
protected $userSession = NULL;

/**
 * action addProduct
 * @param \XX\Ext\Domain\Model\Product $product
 * @return void
 */
public function addProductAction(\XX\Ext\Domain\Model\Product $product) 
{
	$basket = $this->userSession->getBasket();
	$basket->addProduct($product);
	$this->userSession->saveBasket($basket);
	$this->redirect('list', 'Product');
}

/**
 * action removeProduct
 * @param \XX\Ext\Domain\Model\Product $product
 * @return void
 */
public function removeProductAction(\XX\Ext\Domain\Model\Product 
$product){
	$basket = $this->userSession->getBasket();
	$basket->removeProduct($product);
	$this->userSession->saveBasket($basket);
	$this->forward('list', 'Product');
}

And parts from my BasketModel:
--

/**
 * products
 *
 * @var 
\TYPO3\CMS\Extbase\Persistence\ObjectStorage<\XX\Ext\Domain\Model\Product>
 */
protected $products;

/**
 * __construct
 *
 * @return Basket
 */
public function __construct() {
	$this->initStorageObjects();
}

/**
 * Initializes all ObjectStorage properties.
 *
 * @return void
 */
protected function initStorageObjects() {
	$this->products = new \TYPO3\CMS\Extbase\Persistence\ObjectStorage();
}

/**
 * Adds a Product
 *
 * @param \XX\Ext\Domain\Model\Product $product
 * @return void
 */
public function addProduct(\XX\Ext\Domain\Model\Product $product) {
	$this->products->attach($product);
}

/**
 * Removes a Product
 *
 * @param \XX\Ext\Domain\Model\Product $product
 * @return void
 */
public function removeProduct(\XX\Ext\Domain\Model\Product $product) {
	$this->products->detach($product);
}

/**
 * Returns the Products
 *
 * @return 
\TYPO3\CMS\Extbase\Persistence\ObjectStorage<\XX\Ext\Domain\Model\Product> 
$products
 */
public function getProducts() {
	return clone $this->products;
}

/**
 * Sets the Products
 *
 * @param 
\TYPO3\CMS\Extbase\Persistence\ObjectStorage<\XX\Ext\Domain\Model\Product> 
$products
 * @return void
 */
public function 
setProducts(\TYPO3\CMS\Extbase\Persistence\ObjectStorage $products) {
	$this->products = $products;
}

And the BasketView contains the following link:
--

<f:link.action action="removeProduct" arguments="{product : product}"  
controller="Basket" pluginName="Pi1">[remove]</f:link.action>


But calling this link doesn't remove the product. Argument-mapping 
seems to work correctly, as when i vardump the $product param inside 
BasketControllers removeProduct()-Action, the ProductObject seems to be 
as it should. But it doesn't get removed ;)

Can you see any mistake? Currently there seem to be to many trees and i 
can't can't see the forest ;)

Kind regards, Jan
