Ahhh... the line I had in test_controller:
var $uses = array( 'Messages' );
just imports the Messages CONTROLLER, not the MODEL (is that right?!).
To get it to work I had to change it to
var $uses = array( 'Message' ); // Message, not Messages
and then change my index function to:
function index() {
$message = new Message(); // need to add this constructor!
$this->set( 'message', $message->get_welcome_message() );
}
Which looks a bit more messy than I'd like - but I think it's just
because i haven't set up my associations correctly yet.
