How to fetch addSelect query result as single entity?

Question

I got

Foo entity:

class Foo
{
  private $name;

  /**
    * @ORM\OneToMany(targetEntity="App\Entity\Bar", mappedBy="foo", orphanRemoval=true)
    */
  private bars;
  ...
}

Bar entity

class Bar
{
  private $baz

   /**
     * @ORM\ManyToOne(targetEntity="App\Entity\Foo", inversedBy="bars")
     * @ORM\JoinColumn(nullable=false)
     */
  private $foo;
  ...
}

Foo repositiory:

$qb = $this->createQueryBuilder('f')
            ->select('f as foo')
            ->leftJoin('f.bars', 'b')
            ->addSelect('b')
            ->addSelect('SUM(b.baz) as baz_total')
            ->having('SUM(b.baz) > 0')
            ->groupBy('f.id')
            ->orderBy('f.id', 'ASC')->getQuery()->getResult();

a single row the result looks like:

array(
  'foo' => array( // Foo Entity
      ...
      'name' => ...,
      'bars' => array(...)), //ArrayCollection 
  'baz_total' //scalar value 
)

and temple looks like:

{% for row in foos %}
  {{ row.foo.name }}
  {{ row.baz_total}}
{% endfor %}

Is there any way make it works like:

result:

array(
  'name' => ...,
  'bars' => array(...)), //ArrayCollection 
  'baz_total' // extra select as part of entity 
) ...

template:

{% for foo in foos %}
  {{ foo.name }}
  {{ foo.baz_total}}
{% endfor %}

Change your foo repository to:

$qb = $this->createQueryBuilder('f')
            ->select('f, b, SUM(b.baz) as baz_total')
            ->leftJoin('f.bars', 'b')
            ->having('SUM(b.baz) > 0')
            ->groupBy('f.id')
            ->orderBy('f.id', 'ASC')->getQuery()->getResult();

If you want the full entity, just "select" the alias. Symfony will populate the array with the entity.

That should result in your requested result. Not tested.
