Posting to a controller with ajax in CakePHP 2.0

When I post to this controller, I get this back as the response: Fatal error: Call to a member function find() on a non-object in /app/Controller/AppController.php on line 26 which probably has to do with using $this->data() explicitly. I was using CakePHP save without form per a recommendation in there, but since I'm not using a form to send the data (thus not using $this->request->data()), I'd like to know what the replacement is for $this->data() so I can get this working.

My database table is is submissions_favorites.

This is my SubmissionFavorite model:

class SubmissionFavorite extends AppModel {

    var $name = 'SubmissionFavorite';

    var $belongsTo = array(
        'User' => array(
            'className' => 'User'
        )
    );

}

This is AjaxController (what I'm posting to):

class AjaxController extends AppController {

    var $layout = 'ajax';  // uses an empty layout
    var $autoRender = false; // renders nothing by default
    var $uses = 'SubmissionFavorite';

    public function beforeFilter() {
        parent::beforeFilter();
        $this->Auth->loginRedirect = array('controller' => 'home', 'action' => 'index');
        $this->Auth->allow('addFavorite');
        $this->Auth->flashElement = 'flash_error';
    }

public function addFavorite() {
    $this->autoRender = false;

    $this->data['SubmissionFavorite']['user_id'] = $this->Session->read('Auth.User.id');
    $this->data['SubmissionFavorite']['submission_id'] = $_POST['id'];
    $this->data['SubmissionFavorite']['when'] = DboSource::expression('NOW()');

    $message = array('success' => 'success');

    $toReturn = json_encode($message);

    if ($this->RequestHandler->isAjax()) {
        if ($this->Session->read('Auth.User')) {
            $this->SubmissionFavorite->save($this->data);
            return $toReturn;
        } else {
            $login = array('login' => 'Please log in to add favorites');
            return json_encode($login);
        }
    }
}

Line 26 in my AppController is:

protected function getSubmissionCount() {
    $totalSubmissions = $this->Submission->find('count');
    return $totalSubmissions;
}

Which is totally unrelated to anything else. I didn't even add anything to AppController when I wrote the new method within my AjaxController, so I'm not sure how it's relevant (or why I'm even getting an error in that file).

First, following cake conventions, you should name your model SubmissionsFavorite (note the s between Submission and Favorite). This is because your table name is composed by 2 words, even representing a relationship between 2 other tables.

Also, you can't do $this->Submission->... on AppController without telling cake whatever is "Submission". Take a look at this link to see how to initialize Submission model and use it on AppController: Can I use one model inside of a different model in CakePHP?

Regards.

Try to change all 

var $name = 'SubmissionFavorite';

to: 

public $name = 'SubmissionFavorite';

Also change: var $uses = 'SubmissionFavorite';

to: public $uses = array ('SubmissionFavorite');
