Answer 1

Link your models together using associations: CakePHP Associations

Alternatively you can use custom sql-statemens using join e.g.:

$db = $this->getDataSource();
$result = $db->fetchAll(
            "SELECT Soya.id AS Soya__id, Soya.username AS Soya__username FROM public.users AS Soya 
            join Grupo on Grupo.id = Soya.groupo_id
            WHERE Grupo.categoria = ? AND Grupo.subcategoria = ?",
            array('Soya', 'Productor de Oleaginosas')
        );

$this->set('oleaginosas', $result);
