doctrine2 inner join data in object - php

Question

So I am doing two inner joins:
<?php
$q->select('o, pic.path pic1, pic_.path pic2');
$q->innerJoin('\TestBundle\Entity\UserImages', 'pic', 'WITH', 'o.id = pic.user');
$q->where('pic.keyname = \'pic1\'');
$q->innerJoin('\TestBundle\Entity\UserImages', 'pic_', 'WITH', 'o.id = pic.user');
$q->where('pic_.keyname = \'pic2\'');
This works but the returned result is this:
array (size=1)
0 =>
array (size=3)
0 =>
object(TestBundle\Entity\user)[1359]
private 'name' => string 'test' (length=12)
private 'created' =>
object(DateTime)[1347]
...
private 'modified' => null
private 'deleted' => null
private 'id' => int 1
'pic1' => string 'pic1.png' (length=8)
'pic2' => string 'pic2.png' (length=8)
Is there any way to have the pic1 and pic2 be set in the object?
I tried adding setPic1/Pic2 to the Users entity but that didn't work.
What do I have to do to get this to work in the result of the query?
Thanks

Answer 1

I didn't find a way to do what I wanted using just doctrine but since I am using sonota and this is the reason I needed the pic1 and pic2 I created a DataGrid Decorator and intercepted the getResult() method.
In the admin class I override the buildDataGrid (don't have the source code now but I think that was the method) and it will create the datagrid but then I will do something like:
$this->datagrid = new DataGridDecorator($this->datagrid)
The decorator will then change the result given by the method getResult() to what sonata expects and so I don't have to override I don't know how many templates.
Thanks for the help!
