Hi;

X-cart 5.3.2.7
try my first module... unable to get it working..

i try this :http://devs.x-cart.com/en/basics/adding_new_property_to_a_product/adding_product_property_via_formmodel_api.html

I made a simple module, activate it.
I made my folders, with code in it.

i want to store my purchaseprice in database of my products (example '4.99').


Problem:
http://i63.tinypic.com/2dqkar6.jpg

Every value i try tot put in gives a warning 'Test field must be unique'.
A string or number of characters are not stored in database when updating my productdetails.
What is going wrong? Thanks for helps

Main.php

<?php
namespace XLite\Module\Yves\PurchasePrice;

abstract class Main extends \XLite\Module\AModule
{
    /**
     * Author name
     *
     * @return string
     */
    public static function getAuthorName()
    {
        return 'Yves';
    }

    /**
     * Module name
     *
     * @return string
     */
    public static function getModuleName()
    {
        return 'PurchasePrice';
    }

    /**
     * Get module major version
     *
     * @return string
     */
    public static function getMajorVersion()
    {
        return '5.3';
    }

    /**
     * Module version
     *
     * @return string
     */
    public static function getMinorVersion()
    {
        return 0;
    }

    /**
     * Module description
     *
     * @return string
     */
    public static function getDescription()
    {
        return 'Purchae Price Define';
    }
}

Decorate the \XLite\Model\Product class We are creating the <X-Cart>/classes/XLite/Module/XCExample/NewProductFieldDemo/Model/Product.php file with the following content:

<?php

namespace XLite\Module\Yves\PurchasePrice\Model;

use XLite\Core\Cache\ExecuteCachedTrait;
use XLite\Core\Model\EntityVersion\EntityVersionInterface;
use XLite\Core\Model\EntityVersion\EntityVersionTrait;
use XLite\Model\Product\ProductStockAvailabilityPolicy;

class Product extends \XLite\Model\Product implements \XLite\Base\IDecorator
{
    /**
     * @Column (type="string", length=32)
     */
    protected $testField;

    /**
     * Public getter
     * @return string
     */
    public function getTestField() {
      return $this->testField;
    }

    /**
     * Public setter
     * @param string $value
     */
    public function setTestField($value) {
      return $this->testField;
    }
}

To be able to specify value of this property on product details page in admin area, we have to decorate \XLite\View\FormModel\Product\Info class and create <X-Cart>/classes/XLite/Module/XCExample/NewProductFieldDemo/View/FormModel/Product/Info.php file with the following content:

<?php

namespace XLite\Module\Yves\PurchasePrice\View\FormModel\Product;

class Info extends \XLite\View\FormModel\Product\Info implements \XLite\Base\IDecorator
{
    /**
     * @return array
     */
    protected function defineFields()
    {
        $schema = parent::defineFields();

        $schema[self::SECTION_DEFAULT]['testField'] = [
            'label'      => static::t('Test field'),
            'position'   => 100,
        ];

        return $schema;
    }
}

The following code will decorate the class \XLite\Model\DTO\Product\Info (which is responsible for transfering data from product editing page):
**i made a file : XLite\Module\Yves\PurchasePrice\Model\DTO\Product\ Info.php

<?php

namespace XLite\Module\Yves\PurchasePrice\Model\DTO\Product;

use Symfony\Component\Validator\Context\ExecutionContextInterface;
use XLite\Core\Translation;
use XLite\Model\DTO\Base\CommonCell;

/**
 * Product
 */
class Info extends \XLite\Model\DTO\Product\Info implements \XLite\Base\IDecorator
{
    /**
     * Method to initialize default data
     *
     * @param mixed|\XLite\Model\Product $object
     */
    protected function init($object)
    {
        parent::init($object);

        // Here you have all sections data available through $this->default, $this->shipping, $this->marketing etc.
        $this->default->testField = $object->getTestField();
    }

    /**
     * Method which transfers data from DTO to given object (product entity, in our case)
     *
     * @param \XLite\Model\Product $object
     * @param array|null           $rawData
     *
     * @return mixed
     */
    public function populateTo($object, $rawData = null)
    {
        parent::populateTo($object, $rawData);

        // The same here, $this->default, $this->shipping etc. vars contain the state of the field sections.

        $object->setTestField($this->default->testField);
    }

    /**
     * @param Info                      $dto
     * @param ExecutionContextInterface $context
     */
    public static function validate($dto, ExecutionContextInterface $context)
    {
        parent::validate($dto, $context);

        if (!empty($dto->default->testField) && static::isTestFieldUnique($dto)) {
            static::addViolation($context, 'default.testField', Translation::lbl('Test field must be unique'));
        }
    }

    protected static function isTestFieldUnique($dto)
    {
        $testField = $dto->default->testField;
        $identity = $dto->default->identity; // Entity identifier, e.g. product ID

        $entity = \XLite\Core\Database::getRepo('XLite\Model\Product')->findOneByTestField($testField);

        return !$entity || (int) $entity->getProductId() === (int) $identity;
    }
}
