Kohana ORM Relationships and Displaying Information - orm

Question

I don't know how to approach this.
Lets say I have 3 models, A, B, and C.
Model A has many C, Model B has many C, C belongs to A and B.
I get all of B.
$getBs=ORM::factory('B')->find_all();
I display A, B, C.
foreach($getBs as $getB)
{
echo $getB->b_category_title;
foreach($getB->C->find_all() as $getC)
{
echo $getC->c_title;
echo $getA->a_author; //Problem part
}
}
I do not know how to access and connect Model A to Model C when displaying information for Model C.
Edit
To get working code, I change Model A - C to Model One - Three.
Using biakaveron example of _load_with, I get the following error:
Database_Exception [ 1054 ]: Unknown column 'three.id_c' in 'on clause' [ SELECT `ones`.`a_id` AS `ones:a_id`, `ones`.`a_author` AS `ones:a_author`, `three`.* FROM `threes` AS `three` JOIN `twos_threes` ON (`twos_threes`.`id_c` = `three`.`c_id`) LEFT JOIN `ones` AS `ones` ON (`ones`.`a_id` = `three`.`id_c`) WHERE `twos_threes`.`id_b` = '1' ]
Models:
class Model_One extends ORM {
protected $_primary_key = 'a_id';
protected $_has_many = array(
'threes'=> array(
'model' => 'three',
'through' => 'ones_threes',
'far_key' => 'id_c',
'foreign_key' => 'id_a'
),
);
}
class Model_Two extends ORM {
protected $_primary_key = 'b_id';
protected $_has_many = array(
'threes'=> array(
'model' => 'three',
'through' => 'twos_threes',
'far_key' => 'id_c',
'foreign_key' => 'id_b'
),
);
}
class Model_Three extends ORM {
protected $_primary_key = 'c_id';
protected $_belongs_to = array(
'ones'=> array(
'model' => 'one',
'through' => 'ones_threes',
'far_key' => 'id_a',
'foreign_key' => 'id_c'
),
'twos'=> array(
'model' => 'two',
'through' => 'twos_threes',
'far_key' => 'id_b',
'foreign_key' => 'id_c'
),
);
protected $_load_with = array('ones');
}
Why is it looking for three.id_c?

Answer 1

C belongs to A and B.
foreach($getBs as $getB)
{
echo $getB->b_category_title;
foreach($getB->C->find_all() as $getC)
{
echo $getC->c_title;
echo $getC->A->a_author;
}
}
PS. Just a note. You can load both C and A objects using $_load_with property:
class Model_C extends ORM {
// ...
protected $_load_with = array('A');
// ...
}
