Kohana ORM Display Information - orm

Question

I'm trying to learn how to display information from two tables.
Tables:
categories {category_id, category_title}
forums {forum_id, forum_title}
categories_forums {id_category, id_forum}
Models:
class Model_Forum extends ORM {
protected $_primary_key = 'forum_id';
protected $_belongs_to = array(
'categories'=> array(
'model' => 'category',
'through' => 'categories_forums',
'far_key' => 'id_category',
'foreign_key' => 'id_forum'
),
);
}
class Model_Category extends ORM {
protected $_primary_key = 'category_id';
protected $_has_many = array(
'forums'=> array(
'model' => 'forum',
'through' => 'categories_forums',
'far_key' => 'id_forum',
'foreign_key' => 'id_category'
),
);
}
I'm unsure how to display.
So far I have the following:
$categories = ORM::factory('category');
$forums = $categories->forums->find_all();
I don't how to display category_id, category_title, forum_id, forum_title.

Answer 1

You can use foreach loops, like this:
$categories = ORM::factory('category');
foreach ($categories->find_all() as $category){
echo $category->category_title, ' ', $category->id;
}

Answer 2

The following seems to work:
$categories = ORM::factory('category')->find_all();
$view = new View('default/index');
$view->categories = $categories;
$this->response->body($view);
foreach ($categories as $category) :
echo $category->category_title;
echo $category->category_id;
foreach ($category->forums->find_all() as $forum) :
echo $forum->forum_title;
echo $forum->forum_id;
endforeach;
endforeach;
