CakePHP 2.3 Model probleme getting data - cakephp

Question

sorry for my english and i'm new using CAKEPHP 2.3
i get a problem using model association where i can't get "joined data" ( i understand that cakephp get automatically joined data if models are set good , obviously i make it wrong )
I have 2 tables in my database:
departements (with the following columns)
-id
-name
-region_id ( region_id is a foreign key on regions(id) )
regions (with the following columns)
-id
-name
i make two models in cakePhp:
Region.php
<?php
class Region extends AppModel {
var $name = 'Region';
var $actsAs = array( 'Containable' );
public $hasMany = array(
'Departement' => array(
'className' => 'Departement',
'foreignKey' => 'region_id',
'dependent' => false
)
);
}
?>
Departement.php
<?php
class Departement extends AppModel {
var $name = 'Departement';
var $actsAs = array( 'Containable' );
public $belongsTo=array(
'Region' => array(
'className' => 'Region',
'foreignKey' => 'region_id',
'dependent' => false
)
);
}
?>
in a another controller where i need departements and regions, i tryed many thinks but after yours i need your help please !!!
i make this :
first attempt:
<?php
class SignalementsController extends AppController {
public $helpers = array('Html', 'Form');
var $name = 'Signalements';
var $uses = array('Signalements','Regions','Departements','Communes');
public $recursive = 4;
public function index() {
$departements = $this->Departements->find('all');
$this->set('departements', $departements);
}
}
who output in the index view:
array(
(int) 0 => array(
'Departements' => array(
'id' => '1',
'name' => 'AIN',
'region_id' => '82'
)
),
(int) 1 => array(
'Departements' => array(
'id' => '10',
'name' => 'AUBE',
'region_id' => '21'
)
)
...
)
but there is no region joined automatically
second attempt: i change the find models from
$regions = $this->Regions->find('all');
$this->set('regions', $regions);
who output :
array(
(int) 0 => array(
'Regions' => array(
'id' => '11',
'name' => 'ILE-DE-FRANCE'
)
), ... );
but there is no departements joined automatically
last
$fields=array('Region.id','Region.nom','Departement.id','Departement.nom');
$all= $this->Regions->Departements->find('all',$fields);
/* or all this not working as execpted
$all= $this->Departements->Regions->find('all',$fields);
$all= $this->Departements->find('all',$fields);
$all= $this->Regions->find('all',$fields);
*/
$this->set('all', $all);
i try to get the regions data inside each departemts for exemple like this
array(
(int) 0 => array(
'Departements' => array(
'id' => '1',
'nom' => 'AIN',
'region' => array( 'id' => '82', 'nom' => 'POITOU-CHARENTES')
)
),
but i get only this :
array(
(int) 0 => array(
'Departements' => array(
'id' => '1',
'nom' => 'AIN',
'region_id' => '82'
)
),
If you have any idea please leave it
thank you very much

Answer 1

You are using Containable behaviour in your model, so try the find with this:
$departements = $this->Departement->find('all', array('contain' => 'Region'));
Also the maximum level for recursive is 2, setting it to 4 (or 1000) has the effect of 2.

Answer 2

Your ID is of type varchar and should be int.
Also, here is a stripped down version of your code
Region.php
<?php
class Region extends AppModel {
var $actsAs = array( 'Containable' );
public $hasMany = array( 'Departement' );
}
?>
Departement.php
<?php
class Departement extends AppModel {
var $actsAs = array( 'Containable' );
public $belongsTo=array( 'Region' );
}
?>
<?php
class SignalementsController extends AppController {
public $helpers = array('Html', 'Form');
var $uses = array('Signalements','Regions','Departements','Communes');
public function index() {
$this->Departement->recursive = 1;
$departements = $this->Departements->find('all');
$this->set('departements', $departements);
}
}
index.ctp
<?php print_r($departements); ?>
What does it give you?
