Model not using DBGroup

As far as I can tell the database connection is working correctly.  For instance in my controller I can use the following code and get data returned.

PHP Code:

public function index() {

    $db = \Config\Database::connect('publications');
    $builder = $db->table('FiscalYears');
    $builder->select("*");
    $fy = $builder->get()->getResult();

    // Populate the data going to the view
    $data = [
      'fiscalYears' => $fy,
      'title' => 'Fiscal Years',
    ];

    // Generate the view
    echo view('Myth\Auth\Views\layout');
    echo view('FiscalYears/index.php', $data);
  }
