I'm trying to track down a problem with ChoiceField in Symfony2 but I've run
into a dead end.
What I'm trying to do is having a user and a group table in the database and
I want to be able to assign a group to a user using a ChoiceField drop-down.
The Problem is that instead of the correct content in the drop-down it
actually contains a stack-trace with the following php notice:
PHP Notice: Object of class Doctrine\\ORM\\Persisters\\BasicEntityPersister
could not be converted to int in
/var/www/html/symtest/src/vendor/symfony/src/Symfony/Component/Form/ChoiceField.php
on line 118
The User entity contains id, username and ugroup which is defined as
"@orm:ManyToOne(targetEntity="Group")".
The Group entitiy contains id, name and users which is defined as
"@orm:OneToMany(targetEntity="User",mappedBy="ugroup")".
The database looks like this:
mysql> select * from user\G
*************************** 1. row ***************************
id: 1
ugroup_id: 2
username: dennis
1 row in set (0.00 sec)
mysql> select * from ugroup\G
*************************** 1. row ***************************
id: 1
name: user
*************************** 2. row ***************************
id: 2
name: mod
*************************** 3. row ***************************
id: 3
name: admin
3 rows in set (0.00 sec)
and the controller code like this:
$em = $this->get('doctrine.orm.entity_manager');
$urep = $em->getRepository('HelloBundle:User');
$user = $urep->find(1);
$form = new Form('user', $user, $this->get('validator') );
$form->add(new TextField('username'));
$form->add(new ChoiceField('ugroup',array("choices" =>
array("user","mod","admin")) ));
return $this->render('HelloBundle:Hello:index.twig', array('name' =>
$name, 'form' => $form));
This is the most simple test-case i could come up with.
Is there anything special that needs to be done to make this work?
Regards,
Dennis
