$ php test.php

(
[id] => 1
[Translation] => Array
(
[en] => Array
(
[id] => 1
[title] => some title
[body] => test
[lang] => en
)
[fi] => Array
(
[id] => 1
[title] => joku otsikko
[body] => test
[lang] => fi

How do we retrieve the translated data now? This is easy! Lets find all items and their
Finnish translations:
// test.php
Listing
16-47
// ...
$newsItems = Doctrine_Query::create()
->from('NewsItem n')
->leftJoin('n.Translation t')
->where('t.lang = ?')
->execute(array('fi'));
echo $newsItems[0]->Translation['fi']->title;
The above example would produce the following output:
$ php test.php
joku otsikko

NestedSet
The NestedSet behavior allows you to turn your models in to a nested set tree structure
where the entire tree structure can be retrieved in one efficient query. It also provided a nice
interface for manipulating the data in your trees.
Lets take a Category model for example where the categories need to be organized in a
hierarchical tree structure:
// models/Category.php
Listing
16-49
class Category extends Doctrine_Record
{
public function setTableDefinition()
