Can't find model associated model data - cakephp

Question

i'm new in CakePHP and i'm having problems in an example i'm building to learn.
I'm building a plugin with 3 models (Categoria,Plato,Imagen)
The relationships between them are the following:
Categoria - Plato (n-n)
Plato - Imagen (1-n)
If I go to Plato view, I get all Imagen by the relationship, but when I access through a category, I can't just reach the Imagen associated with each Plato. Why? What's the problem?
Models code:
Plato:
App::uses('AppModel', 'Model');
class Plato extends ErestaurantAppModel {
public $name = 'Plato';
//public $actsAs = array('Containable');
public $hasAndBelongsToMany = array(
'Categoria' => array(
'className' => 'Categoria',
'joinTable' => 'categorias_platos',
'foreignKey' => 'plato_id',
'associationForeignKey' => 'categoria_id',
'unique' => 'keepExisting',
'conditions' => '',
'fields' => '',
'order' => '',
'limit' => '',
'offset' => '',
'finderQuery' => '',
)
);
public $hasMany = array('Imagen' =>
array('foreingkey' => array('plato_id')));
}
Categoria:
App::uses('AppModel', 'Model');
class Categoria extends ErestaurantAppModel {
public $name = 'Categoria';
//public $actsAs = array('Containable');
public $hasAndBelongsToMany = array(
'Plato' => array(
'className' => 'Plato',
'joinTable' => 'categorias_platos',
'foreignKey' => 'categoria_id',
'associationForeignKey' => 'plato_id',
'unique' => 'keepExisting',
'conditions' => '',
'fields' => '',
'order' => '',
'limit' => '',
'offset' => '',
'finderQuery' => '',
)
);
}
Imagen:
App::uses('AppModel', 'Model');
class Imagen extends ErestaurantAppModel {
public $name = 'Imagen';
//public $actsAs = array('Containable');
public $belongsTo = array('Plato');
}
Finally, the code I'm launching when i go to a Categoria view.
App::uses('AppController', 'Controller');
class CategoriasController extends ErestaurantAppController {
public $uses = array('Erestaurant.Categoria');
public function index() {
$this->Categoria->recursive = 0;
$this->set('data', $this->Categoria->find('all'));
}
public function view($id = null) {
if (!$this->Categoria->exists($id)) {
throw new NotFoundException(__('Registro inválido.'));
}
/*
$this->Categoria->recursive = -1;
$options = array('conditions' =>
array('Categoria.'.$this->Categoria->primaryKey => $id),
'contain' => array(
'Plato' => array(
'Imagen'
)
)
);
*/
$this->Categoria->recursive = 2;
$options = array('conditions' =>
array('Categoria.'.$this->Categoria->primaryKey => $id));
$this->set('item', $this->Categoria->find('first', $options));
}
}
The commented code you see it's another way I tried, using Containable, but at the end I get error "Plato is not associated with model Imagen"
Database seems all ok, with each table created as needed (categorias, platos, imagens, categorias_platos) and with all foering keys created and trying to keep CakePHP default names.
Thank you!

To access deep relations you must use containable behavior. You have a definition of containable behavior in your model, but for some reason it is commented.
public $actsAs = array('Containable');
Uppon uncommenting this line in your Categoria, you can access deep relations in this way:
$this->Categoria->find('all', array(
'contain'=>array(
'Plato.Imagen'
)
));
...or something like this. For more information plase visit this link Containable Behavior
