Symfony2 TWIG show user from know ID - php

Question

I have a list of tasks stored in the doctrine database which I return like this:
$task = $this->getDoctrine()
->getRepository('SeotoolMainBundle:Tasks')
->findAll();
return array('form' => $form->createView(), 'message' => '', 'list_tasks' => $task);
In one row the ID of and entry from a second table is stored. I don't want only output the ID but also the Name, Description and so on stored in the other table. With normal PHP & MYSQL this would be done by using JOIN - how can I do it with Symfony & TWIG ?
Twig Output:
{% for task in list_tasks%}
{{ task.Id }}
{{ task.TaskTitle }}
{{ task.TaskDescription }}
{{ task.TaskTypes }} /* Here I want not only get the ID but also other fields stored in the database with TaskType ID = task.TaskTypes */
{{ task.User }} /* Here I want not only get the ID but also other fields stored in the database with User ID = task.User */
{% endfor %}

Answer 1

I am assuming that TaskType and User are entities, which belong within the Tasks entity. In which case, try the following. Note that I am getting just one task with id of 1 in my example:
$task = $this->getDoctrine()->getRepository('SeotoolMainBundle:Tasks')->find(1);
$taskTypes = $task->getTaskTypes();
$user = $task->getUser();
return array(
'form' => $form->createView(),
'message' => '',
'list_tasks' => $task,
'task_types' => $taskTypes,
'user' => $user,
);
And in your Twig:
{% for task_type in task_types %}
{{ task_type.Id }} // or whatever fields a task_type has
{% endfor %}
And the same for the user
Edit:
As you are wanting to have ALL tasks processed at once, I wonder if simply the following willl work:
{% for task_list in task_lists %}
{% for task_type in task_list.taskType %}
{{ task_type.Id }} // or whatever fields a task_type has
{% endfor %}
{% endfor %}

I did it now on this way, but I dont think, that it is 100% correct and conform.
How to do better? Luckily this works for me actually:
$task = $this->getDoctrine()
->getRepository('SeotoolMainBundle:Tasks')
->findAll();
$taskTypes = $this->getDoctrine()
->getRepository('SeotoolMainBundle:TaskTypes')
->findAll();
$user = $this->getDoctrine()
->getRepository('SeotoolMainBundle:User')
->findAll();
return array(
'form' => $form->createView(),
'message' => '',
'list_tasks' => $task,
'list_task_types' => $taskTypes,
'list_user' => $user
);
TWIG:
{% for task in list_tasks %}
Task ID: {{ task.ID }} <br/>
{% for type in list_task_types if type.id == task.tasktypes %}
{{ type.tasktypetitle }} <br/>
{% endfor %}
{% for user in list_user if user.id == task.user %}
{{ user.username }} <br/>
{% endfor %}
<hr/>
{% endfor %}
