访问主义查询中的元素不起作用

Question

I have a Doctrine query, where the "JOIN p.product pr" is joining in the Product Table and all of its info (id, name, qty, status, created, updated, deletedAt, etc...)

Custom function in my repository class...

 $query = $this->getEntityManager()
        ->createQuery('
        SELECT      p
        FROM        WIC\PurchaseOrderBundle\Entity\PurchaseOrderProductsStatus p
        JOIN        p.product pr
        WHERE       p.inventoryLocation = :id
        AND         p.account = :account_id')
        ->setParameter('id', $id)
        ->setParameter('account_id', $account_id);

    try{
        return $query->getArrayResult();
    }catch (\Doctrine\ORM\NoResultException $e) {
        return $e;
    }

In my controller I am sending the array into a twig template...

 $productActions = My custom function query listed above which returns array

 return array(
        'heading' => 'Inventory Staging Location',
        'productActions' => $productActions,
    );

In my Twig template I am now trying to loop through the records...

 {% for productAction in productActions %}
                        <tr>
                            <td>{{ productAction.product.sku }}</td>
                            <td>{{ productAction.product.name }}</td>
                            <td></td>
                        </tr>
                    {% endfor %}

I am getting this error...

 Key "product" for array with keys "id, qty, status, created, updated, deletedAt" does not exist in ...

What Am I doing wrong?

When I do my query by doing a ->findBy() everything seems to work fine. This array works when sent to the twig template

 $productActions = $em->getRepository('WICPurchaseOrderBundle:PurchaseOrderProductsStatus')->findBy(array(
            "inventoryLocation"=>$inventoryLocation,
            "account"=>$account_id,
        )); 

Thanks!

You need to request pr in SELECT part ;)

$query = $this->getEntityManager()
        ->createQuery('
        SELECT      p, pr
        FROM        WIC\PurchaseOrderBundle\Entity\PurchaseOrderProductsStatus p
        JOIN        p.product pr
        WHERE       p.inventoryLocation = :id
        AND         p.account = :account_id')
        ->setParameter('id', $id)
        ->setParameter('account_id', $account_id);

    try{
        return $query->getArrayResult();
    }catch (\Doctrine\ORM\NoResultException $e) {
        return $e;
    }
