Hi all. i hope you can help me.
I am working with doctrineextensions nestedset. i am trying to build a
multilingual tree.
I created 2 entities:
- Node (the tree, type nested. Has one-to-many relation with
NodeContent )
- NodeContent (contains node translations. It should have a reference
to the node id)
All data are correctly inserted in the tables except the relation id
when i persist an object from the controller (null value is inserted).
I don't understand what is wrong because onetomany relation works
without using tree extension.
I thiink creating a multilingual tree bundle would be very useful :)
Thanks!!
This is my controller:
/******************************* Controller
***************************************/
..
$newNode = new Node();
$parentNode = $node->findOneById(str_replace('item_', '', $parentId));
$newNode->setTitle($title);
$newNode->setParent($parentNode);
$languages = array('it','en','fr');
foreach($languages as $language){
$newNodeContent = new NodeContent();
$newNodeContent->setLanguage($language);
$newNodeContent->setTitle($title.'_'.$language);
$newNode->addNodeContent($newNodeContent);
}
$em->persist($newNode);
$em->flush();
...
And these are the classes:
/******************************* Node
