cakephp有关问题

cakephp问题
这个是我写的代码:

<?php <br />  class BooksController extends AppController<br />  {<br />  	var $name='Books';<br />  	var $help='form';<br />function index() { <br />$this->Book->recursive = 1; <br />$books = $this->Book->find('all',array('field'=>array('Book.isbn','Book.title','Author.name'))); <br />$this->set('books', $books); <br />} <br />function add()<br />{<br />   if(!empty($this->data))<br />   {<br />      $this->Book->create();<br />      $this->Book->save($this->data);<br />      $this->redirect(array('action'=>'index'));<br />   }<br />    $authors = $this->Book->Author->generateList();<br />      $this->set('$authors',$authors);<br />}<br />} 		<br />?>

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();
