cakephp model association (view) - cakephp

Question

In cakephp I have codesets and codesetitems. codesetitems belong to codesets so in my codesetitems I have belongsTo = 'Codeset'. But in my view I don't seem to be able to call $codeset['Codesetitem']['id']. It says undefined index Codesetitem. I already checked out the cake documentation. One codeset can have many codesetitems.

Explanation about how cakephp handle and output array of result.
In order to get associated result you must define it in each model as below.
CodesetItem Model
<?php
class CodesetItem extends AppModel
{
var $name = 'CodesetItem';
var $belongsTo = array
(
'Codeset' => array
(
'className' => 'Codeset',
'foreignKey' => 'codeset_id',
'conditions' => '',
'fields' => '',
'order' => ''
)
);
}
?>
Codeset Model
<?php
class Codeset extends AppModel
{
var $name = 'Codeset';
var $hasMany = array
(
'CodesetItem' => array
(
'className' => 'CodesetItem',
'foreignKey' => 'codeset_id',
'dependent' => false,
'conditions' => '',
'fields' => '',
'order' => '',
'limit' => '',
'offset' => '',
'exclusive' => '',
'finderQuery' => '',
'counterQuery' => ''
)
);
}
?>
Codeset Controller
<?php
class CodesetsController extends AppController
{
var $name = 'Codesets';
function beforeFilter()
{
parent::beforeFilter();
}
function index()
{
$codesets = $this->Codeset->find('first');
pr($codesets);
exit;
}
}
?>
Above will out put array of codeset with index of 0 means as below
Array
(
[Codeset] => Array
(
[id] => 121
[name] => Gwoo the Kungwoo
[created] => 2007-05-01 10:31:01
)
[CodesetItem] => Array
(
[0] => Array
(
[id] => 123
[codeset_id] => 121
[title] => On Gwoo the Kungwoo
[body] => The Kungwooness is not so Gwooish
[created] => 2006-05-01 10:31:01
)
[1] => Array
(
[id] => 124
[codeset_id] => 123
[title] => More on Gwoo
[body] => But what of the ‘Nut?
[created] => 2006-05-01 10:41:01
)
)
)
but when you use find('all') in find method it will out as below.
Array
(
[0] => Array
(
[Codeset] => Array
(
[id] => 121
[name] => Gwoo the Kungwoo
[created] => 2007-05-01 10:31:01
)
[CodesetItem] => Array
(
[0] => Array
(
[id] => 123
[codeset_id] => 121
[title] => On Gwoo the Kungwoo
[body] => The Kungwooness is not so Gwooish
[created] => 2006-05-01 10:31:01
)
[1] => Array
(
[id] => 124
[codeset_id] => 121
[title] => More on Gwoo
[body] => But what of the ‘Nut?
[created] => 2006-05-01 10:41:01
)
)
)
[1] => Array
(
[Codeset] => Array
(
[id] => 121
[name] => Gwoo the Kungwoo
[created] => 2007-05-01 10:31:01
)
[CodesetItem] => Array
(
[0] => Array
(
[id] => 123
[codeset_id] => 121
[title] => On Gwoo the Kungwoo
[body] => The Kungwooness is not so Gwooish
[created] => 2006-05-01 10:31:01
)
[1] => Array
(
[id] => 124
[codeset_id] => 121
[title] => More on Gwoo
[body] => But what of the ‘Nut?
[created] => 2006-05-01 10:41:01
)
)
