Symfony3 - Left Join does not work properly - symfony

Question

Trying to solve this problem with Join in Symfony3.
Somehow the resultset has mixed up values, i.e
ID Exploit Author
ID Author Author
Please see the attached screenshot.
OpenX should have Author Metasploit and the second row shouldn't be there.
Have this code in the controller:
public function indexAction()
{
$exploits = $this->getDoctrine()
->getRepository('AppBundle:Exploit')->createQueryBuilder('e')
->add('select', 'a,e')
->add('from', 'AppBundle:Exploit e')
->leftJoin('AppBundle:Author', 'a')
->where('e.author = a.id')
->getQuery()
->getResult();
return $this->render('exploit/index.html.twig', array(
'exploits' => $exploits
));
}
This view:
<tbody>
{% for exploit in exploits %}
<tr>
<th scope="row">{{ exploit.id }}</th>
<td>{{ exploit.name }}</td>
<td> {{ exploit.author }} </td>
<td>
View
Edit
Delete
</td>
</tr>
{% endfor %}
And these Entities:

Anybody know how to correct my join query ? Or why it behaves like this?
Thanks,

Answer 1

Try this:
->leftJoin('AppBundle:Author', 'a', "WITH", "e.author = a.id")
Instead of this:
->leftJoin('AppBundle:Author', 'a')
->where('e.author = a.id')

Answer 2

Try
public function indexAction()
{
$exploits = $this->getDoctrine()
->getRepository('AppBundle:Exploit')->createQueryBuilder('e')
->leftjoin('e.author','a')
->addSelect('a')
->getQuery()
->getResult();
return $this->render('exploit/index.html.twig', array(
'exploits' => $exploits
));
}
and in the view
<tbody>
{% for exploit in exploits %}
<tr>
<th scope="row">{{ exploit.id }}</th>
<td>{{ exploit.name }}</td>
<td> {{ exploit.author.name }} </td>
<td>
View
Edit
Delete
</td>
</tr>
{% endfor %}
</tbody>
