Question

In Symfony 2 book there is an example of how to do that for ONE $product: http://symfony.com/doc/2.0/book/doctrine.html#fetching-related-objects

It is quite simple:

public function showAction($id)
{
$product = $this->getDoctrine()
    ->getRepository('AcmeStoreBundle:Product')
    ->find($id);

$categoryName = $product->getCategory()->getName();

// ...
}

But what if i want to fetch ALL products with category info joined automatically to each project?

Thank you!

Answer 1

This will do the trick:

$products = $this->getDoctrine()->getRepository('AcmeStoreBundle:Product')->findAll();

However, each time you do a getCategory on a product a sql query will be triggered which could result in performance issues.

What you really want to do is to make yourself a ProductManager service and write an explicit query joining product and category. So only one sql query will be generated. The Doctrine 2 manual has plenty of examples.
