ProductCountry module (Zed)

First, you need to create a new table with the name pyz_product_country. This table will be filled with demo data provided by a hard coded sku/country list in the ImportController of the module.

File: Pyz/Zed/ProductCountry/Persistence/Propel/Schema/pyz_product_country.schema.xml

<?xml version="1.0"?>
<database xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    name="zed"
    xsi:noNamespaceSchemaLocation="http://static.spryker.com/schema-01.xsd"
    namespace="Orm\Zed\ProductCountry\Persistence"
    package="src.Orm.Zed.ProductCountry.Persistence">

    <table name="spy_product_country" idMethod="native" allowPkInsert="true">
        <column name="id_product_country" required="true" type="INTEGER" autoIncrement="true" primaryKey="true"/>
        <column name="fk_product" required="true" type="INTEGER"/>
        <column name="fk_country" required="true" type="INTEGER"/>

        <foreign-key foreignTable="spy_country">
            <reference local="fk_country" foreign="id_country"/>
        </foreign-key>

        <foreign-key foreignTable="spy_product_abstract">
            <reference local="fk_product" foreign="id_product_abstract"/>
        </foreign-key>

        <id-method-parameter value="spy_product_country_pk_seq"/>
    </table>

</database>

Next, call the console propel:install console command in order to migrate the database and create the query objects.

Method: Pyz\Zed\ProductCountry\Communication\Controller\ImportController::indexAction()

<?php

class ProductCountryQueryContainer extends AbstractQueryContainer implements ProductCountryQueryContainerInterface
{
    //...

    /**
     * @param int $idProduct
     * @param int $idCountry
     *
     * @return \Orm\Zed\ProductCountry\Persistence\SpyProductCountryQuery
     */
    public function queryProductCountry($idProduct, $idCountry)
    {
        $query = $this->getFactory()->createProductCountryQuery();
        $query->filterByFkProduct($idProduct);
        $query->filterByFkCountry($idCountry);

        return $query;
    }

    //...
}

In the ProductCountryBusinessFactory class you need to create a new instance of the ProductCountryManager. The dependency to the product module facade is missing in the class. Create a new method getProductFacade that returns the facade from the ProductCountryDependencyProvider.

Click to expand the code sample
<?php

class ProductCountryBusinessFactory extends SprykerBusinessFactory
{

    /**
     * @return \Pyz\Zed\ProductCountry\Business\Model\ProductCountryManagerInterface
     */
    public function createProductCountryManager()
    {
        return new ProductCountryManager(
            $this->getProductFacade(),
            $this->getCountryFacade(),
            $this->getQueryContainer(),
            $this->getPropelConnection()
        );
    }

    // ...

    /**
     * @return \Pyz\Zed\Product\Business\ProductFacadeInterface
     */
    public function getProductFacade()
    {
        return $this->getProvidedDependency(ProductCountryDependencyProvider::PRODUCT_FACADE);
    }

    //...

}

Now, implement the logic to save a new product, within the ProductCountryManager.

<?php

class ProductCountryManager implements ProductCountryManagerInterface
{
    //...

    /**
     * @param array $productCountryData Product SKU => Country ISO 2 Code
     *
     * @throws \Exception
     *
     * @return void
     */
    public function importProductCountryData(array $productCountryData)
    {
        foreach ($productCountryData as $productCountrySku => $productCountryIso2Code) {
            $this->saveProductCountryEntity($productCountrySku, $productCountryIso2Code);
        }
    }

    /**
     * @param $productCountrySku
     * @param $productCountryIso2Code
     * @throws \Propel\Runtime\Exception\PropelException
     */
    private function saveProductCountryEntity($productCountrySku, $productCountryIso2Code)
    {
        try {
            $productId = $this->productFacade->getProductAbstractIdByConcreteSku($productCountrySku);
            $countryId = $this->countryFacade->getIdCountryByIso2Code($productCountryIso2Code);

            $countryEntity = new SpyProductCountry();
            $countryEntity->setFkProduct($productId);
            $countryEntity->setFkCountry($countryId);

            $countryEntity->save($this->connection);

            // Touch product to trigger collector for key/value export
            $this->productFacade->touchProductActive($productId);

        } catch (\Exception $e) {
            echo $e->getMessage();
        }
    }

    //...

}

Collector module (Zed)

The collector is used to transfer data from the SQL storage to the key-value storage. The collector must be extended with the new field “product_country”.

Open Pyz/Zed/Collector/Persistence/Storage/Pdo/PostgreSql/ProductCollectorQuery.php and extend the collector SQL query with a left join to the new created table spy_product_country in order to load and select the country name where each product is produced.

SELECT
    ...
    spy_country.name AS product_country
FROM
    ...
...
LEFT JOIN spy_product_country ON (spy_product_country.fk_product = spy_product_abstract.id_product_abstract)
LEFT JOIN spy_country ON (spy_country.id_country = spy_product_country.fk_country)
...

Now we need to add the new selected column product_country to the collectItem list in Pyz\Zed\Collector\Business\Storage\ProductCollector.

Click to expand the code sample
<?php

class ProductCollector extends AbstractStoragePdoCollector
{
    //...

    /**
     * @param string $touchKey
     * @param array $collectItemData
     *
     * @return array
     */
    protected function collectItem($touchKey, array $collectItemData)
    {
        return [
            'abstract_product_id' => $collectItemData[CollectorConfig::COLLECTOR_RESOURCE_ID],
            'abstract_attributes' => $this->getAbstractAttributes($collectItemData),
            'abstract_name' => $collectItemData['abstract_name'],
            'abstract_sku' => $collectItemData['abstract_sku'],
            'url' => $collectItemData['abstract_url'],
            'available' => true,
            'valid_price' => $this->getValidPriceBySku($collectItemData['abstract_sku']),
            'prices' => $this->getPrices($collectItemData),
            'category' => $this->getCategories($collectItemData[CollectorConfig::COLLECTOR_RESOURCE_ID]),

             // new line
            'product_country' => $collectItemData['product_country']
        ];
    }

    //...
}

Product module (Yves)

Open Pyz/Yves/Product/Theme/default/product/detail.twig and add the following code:

{% if product.product_country %}
<dt>{{ "page.product_country"|trans }}</dt>
<dd>{{ product.product_country }}</dd>
{% endif %}
