cakephp有关问题

cakephp问题
这个是我写的代码:

  class BooksController extends AppController

  {

  	var $name='Books';

  	var $help='form';

function index() { 

$this->Book->recursive = 1; 

$books = $this->Book->find('all',array('field'=>array('Book.isbn','Book.title','Author.name'))); 

$this->set('books', $books); 

} 

function add()

{

   if(!empty($this->data))

   {

      $this->Book->create();

      $this->Book->save($this->data);

      $this->redirect(array('action'=>'index'));

   }

    $authors = $this->Book->Author->generateList();

      $this->set('$authors',$authors);

}

} 		

?>

然后出现这个问题

该怎样解决呢？

估计是这句$authors = $this->Book->Author->generateList(); 有问题试试$authors = $this->Book->generateList();
