Symfony 3.4 Doctrine: Change referenced table on runtime - php

Question

In my symfony application products are stored in the table products. There is an Entity Product and Repository ProductRepository for it.
Some products automatically get archived and stored in another table, called products_archived. I created an Entity ProductArchived and duplicated the ProductRepository file to the file ProductArchivedRepository.php.
The tables products and products_archived have exactly the same structure and fields.
My goal:
When in the code a product is identified as an archived product, I want to be able to apply a function from the ProductRepository and NOT having to refer to a separate ProductArchivedRepository. I want to avoid having to use duplicated code.
Example:
ProductRepository.php:
public function getProductDataById($productId)
{
$qb = $this->createQueryBuilder('p');
// ...
return $qb->getQuery()->getArrayResult();
}
ProductArchivedRepository.php:
public function getProductDataById($productId)
{
$qb = $this->createQueryBuilder('p');
// ...
return $qb->getQuery()->getArrayResult();
}
ProductService.php:
public function getProductDataById($productId)
{
$repoProduct = $this->productRepository;
$repoProductArchived = $this->container->productArchivedRepository;
if ($repoProduct->findOneBy(['id' => $productId]) instanceof Product) {
$repoP = $repoProduct;
} else if ($repoProductArchived->findOneBy(['id' => $productId]) instanceof ProductArchived) {
$repoP = $repoProductArchived;
} else {
throw new NotFoundHttpException(
'Product neither found in table product nor in table product_archived.'
);
}
$productData = $repoP->getProductDataById($productId);
return $productData;
}
How do I achieve that ProductArchivedRepository.php becomes redundant?

Answer 1

You can use an abstract class that regroup the duplicated method(s)
abstract class AbstractProductRepository extends EntityRepository
{
public function getProductDataById($productId)
{
$qb = $this->createQueryBuilder('p');
// ...
return $qb->getQuery()->getArrayResult();
}
}
And now, both of your repository can extend the abstract class instead of EntityRepository :
class ProductRepository extends AbstractProductRepository
{
// ...
}
class ProductArchivedRepository extends AbstractProductRepository
{
// ...
}
