Symfony 2和Doctrine2-在Doctrine查询构建器中使用join时，如何使用列名作为数组键？

Question

My problem

I am performing a join using doctrine2 query builder and symfony3 .

My controller contains following code:

$rp_konta = $this->getDoctrine()->getRepository('AppBundle:konto');
$query = $rp_konta->createQueryBuilder('p')
            ->select('p')
            ->addSelect('SUM(g.kwota)')
            ->leftJoin('p.ksiegowaniaWinien', 'g')
            ->getQuery();

which results in the SQL query:

SELECT k0_.id AS id_0, k0_.kod_konta AS kod_konta_1, k0_.nazwa_konta AS nazwa_konta_2, k0_.typ_konta AS typ_konta_3, k0_.aktywne AS aktywne_4, SUM(d1_.kwota) AS sclr_5 FROM konto k0_ LEFT JOIN dziennik d1_ ON k0_.id = d1_.konto_winien_id AND (d1_.usuniety IS NULL) WHERE k0_.id IN ('1', '2', '3');

Please note that each column name is followed by a suffix id _0 , kod_konta _1 and so on.

As my twig template looks like the following:

{% for konto in konta_pagination %}
<tr>
    <td>{{ konto.id }}</td>
{% endfor %}

and the id column returned as a result of SQL query is marked by doctrine as id_0 and not as id I get the following error:

Key "id" for array with keys "0, 1" does not exist in AppBundle::/raport/saldaKont.html.twig at line 18

How should I modify the query so that it returns the array with keys consistent without any suffix?

Update 1: Entities code

Based on @Tiriel request please find below also my entities code.

Dziennik entity :

class dziennik
{
    /**
     * @ORM\Column(type="integer")
     * @ORM\Id
     * @ORM\GeneratedValue(strategy="AUTO")
     */
    protected $id;
/.../
 /**
     * @ORM\ManyToOne(targetEntity="konto", inversedBy="ksiegowaniaWinien")
      * @Gedmo\Versioned
     */
     protected $kontoWinien;

      /**
     * @ORM\ManyToOne(targetEntity="konto", inversedBy="ksiegowaniaMa")
      * @Gedmo\Versioned
     */
     protected $kontoMa;
}

Konto entity :

class konto
{
    /**
     * @ORM\Column(type="integer")
     * @ORM\Id
     * @ORM\GeneratedValue(strategy="AUTO")
     */
    protected $id;

/.../

    /**
     * @ORM\OneToMany(targetEntity="dziennik", mappedBy="kontoWinien")
     */
     protected $ksiegowaniaWinien;

     /**
     * @ORM\OneToMany(targetEntity="dziennik", mappedBy="kontoMa")
     */
     protected $ksiegowaniaMa;

}

Answer 1

Try putting your addSelect('SUM(g.kwota)') AFTER your leftJoin('p.ksiegowaniaWinien', 'g') (at least that's the way I learned, mybe it'll fix your problem).

Otherwise, we need to see your entities. To me, you must have a column name id in each table, and so Doctrine has to suffix each one in it's query. It has never made any problem in my code, but maybe here...
