Symfony2 set value for formfield in controller - php

Question

I'm getting following exception, when I try to add a task and automaticly add the current user to the accordion field of the task:
Catchable Fatal Error: Argument 1 passed to Seotool\MainBundle\Entity\Task::setUser() must be an instance of Seotool\MainBundle\Entity\User, string given, called in /Applications/MAMP/htdocs/Seotool/vendor/symfony/symfony/src/Symfony/Component/PropertyAccess/PropertyAccessor.php on line 438 and defined in /Applications/MAMP/htdocs/Seotool/src/Seotool/MainBundle/Entity/Task.php line 174
My Controller looks like this:
/**
#Route(
* path = "/taskmanager/user/{user_id}",
* name = "taskmanager"
* )
* #Template()
*/
public function taskManagerAction($user_id, Request $request)
{
/* #### NEW TASK FORM #### */
$task = new Task();
$addTaskForm = $this->createForm(new TaskType(), $task);
$addTaskForm->handleRequest($request);
if($addTaskForm->isValid()):
$task->setDone(FALSE);
$task->setUser($user_id);
$task->setDateCreated(new \DateTime());
$task->setDateDone(NULL);
$em = $this->getDoctrine()->getManager();
$em->persist($task);
$em->flush();
return $this->redirect($this->generateUrl('taskmanager', array('user_id' => $user_id)));
endif;
Line 174 in Entity/Task.php:
/**
* Set User
*
* #param \Seotool\MainBundle\Entity\User $user
* #return Task
*/
public function setUser(\Seotool\MainBundle\Entity\User $user = null)
{
$this->User = $user;
return $this;
}
Does anybody know how to set the value for my hidden "user" form field with $user_id value?
Thanks in advance

Answer 1

You can't do
$task->setUser($user_id);
because $user_id, here, is a string and your method signature expects an object of Seotool\MainBundle\Entity\User type.
You can proceed in two ways, depending on your needs (but I suppose that only second option will be suitable for you):
1) Modify your setUser() function if you don't need a reference (ORM oriented) or User Object into your Task Object
public function setUser($user = null)
{
$this->User = $user;
return $this;
}
2) Retrieve current user and set it
public function taskManagerAction($user_id, Request $request)
{
[...]
if($addTaskForm->isValid()):
$user = $this->get('security.context')->getToken()->getUser();
$task->setUser($user);
[...]
endif;
$this->get('security.context')->getToken()->getUser(); gives you current logged user but, maybe, you need to change signature aswell (possible inheritance issues?)
