Call to a member function create() on a non-object

I'm trying to create a new record on a table called tutors. I named it that way in order to follow CakePHP conventions.

$codigoAlumnoNuevo = $this->Persona->id;
$tipoPersona = $this->request->data('TipoPersona'); # Just grabbing a POSTED value.

switch ($tipoPersona) {
    case '0': # Es Tutor
        $this->Tutor->create();
        $this->Tutor->PersonaId = $codigoAlumnoNuevo;
        $this->Tutor->save();
        die("Saved record");
        break;

    case '1': # Es Alumno
        $this->Tutor->create();
        $this->Tutor->PersonaId = $codigoAlumnoNuevo;
        $this->Tutor->save();
        die("Saved record");
    break;

    case '2': # Es Coordinador de Programa
        $this->Tutor->create();
        $this->Tutor->PersonaId = $codigoAlumnoNuevo;
        $this->Tutor->save();
        die("Saved record");
    break;

    default:
        break;
}

When trying to run this code, the following exception fires:

Call to a member function create() on a non-object

If I try this, I can see that $this->Tutor is NULL:

var_dump($this->Tutor);

But in the same controller, I can call $this->Persona->create(); just fine; $this->Persona is not null. Why is this? Why is Persona available but not Tutor?

Is it a naming thing?

Here's my database model:

If you defined a hasMany relationship between Persona and Tutor in your Persona model, you can access the Tutor model with $this->Persona->Tutor->create() and the $uses array from Joseph's answer is not necessary.

From your PersonasController you can only access the Persona model by default.

If you want to run creates on the Tutor model, you need to add var $uses = array('Persona','Tutor'); to the beginning of your PersonasController.php like so:

<?php
class PersonasController extends AppController {
    var $uses = array('Persona','Tutor');

    ....functions.....

}
?>
