You can use beforeFind Model's callback otherwise Model constructor. I
prefer beforeFind method.
class AppModel extends Model {
[...]
public function __construct($id = false, $table = null, $ds =
null) {
// Set here virtualFields ($this->virtualFields = X)
$this->virtualFields = array(
'name' => 'LEFT('. $this->name .'_'.description,
40)'
);
parent::__construct($id, $table, $ds);
}
public function beforeFind($queryData) {
// Set here virtualFields ($this->virtualFields = X)
}
}
