Twig templates & Doctrine proxy object - symfony 2.2.0-RC2 #7122

If you have for example "Item" entity with many to one relation between them and "Group" entity. In "Item" entity "group" parameter represents "Group" entity where it belongs with getter "getGroup" and setter "setGroup". "Group" consists "title" parameter with getter "getTitle" and setter "setTitle"

In controller for example you find one item with item id and pass that item to twig template as variable "item". In "item" object "group" parameter is now doctrine proxy object.

If you try to do this in twig template

{{ item.group.title }}

you will get this error

Twig_Error_Runtime: Item "title" for "Array" does not exist in "<some_twig_template>" at line <some_line>

Only parameter that twig can access in "item.group" object is "isInitialized".

Can you copy/paste your entities ? And also show us your controller that retrieve the item ?

In previous example I tried to simplify things. This is the real entities.

User Entity: https://gist.github.com/dalibor983/4985875

CityDefinition Entity: https://gist.github.com/dalibor983/4985914

XML mappings for this two entities: https://gist.github.com/dalibor983/4985919

Controller code

$username = <some_username>;
$manager = $this->getDoctrine()->getManager();
$r = $manager->getRepository('<some_bundle>:User');
/* @var User $user */
$user = $r->findOneBy(array('loginUsername' => $username));
return $this->render('<some_twig>', array(
    'userData' => $user,
));

Twig consists

{{ userData.cityDefinition.longName }}

@dalibor983 Could you move this code to gist? It makes this issue really unreadable...

The code above works in simfony 2.1 but not in 2.2.0RC2. I'm trying to upgrade from 2.1 to 2.2.0RC2

I also use this in twig template:

{{ render(controller("<some_bundle>:Example:index", {"cityDef": userData.cityDefinition})) }}

and in "ExampleController:index" i have

public function indexAction($cityDef)
{
    $this->render(<some_twig>, array("cityDef" => $cityDef));
}

and in twig

{{ cityDef.longName }}

I also get error.

I noticed that this twig call:

{{ render(controller("<some_bundle>:Example:index", {"cityDef": userData.cityDefinition})) }}

transformed "userData.cityDefinition" proxy object to array with one element "isInitialized => '1'" and
in "ExampleController:indexAction" I got this array for "$cityDef" parameter instead of proxy object.
