CakePHP错误：在此服务器上找不到请求的地址'/ unsigned_images / index'

Question

我是初学者Cakephp开发人员。我遇到错误：在此服务器上找不到请求的地址'/ unsigned_images / index'。

我使用以下代码：

型号：app / models / unsigned_image.php

<?php
class UnsignedImage extends AppModel{

    var $name = 'UnsignedImage';
    var $useDbConfig = 'tabletApp';
    var $useTable = 'unsigned_images';
    //var $useTable = false;

}
?>

控制器：app / controllers / unsigned_images_controller.php

<?php
class UnsignedImagesController extends AppController{

    var $name = 'UnsignedImages';
    var $pageTitle = 'Hello world!';
    var $helpers = array('javascript');
    var $components = array('Auth', 'Slogic');

    function index(){
        $this->layout = 'default';
        $this->set('data','Hello World!');
        $this->set('unsigned_images', $this->UnsignedImage->find('all') );
    }
}
?>

查看：app / views / unsigned_images / index.ctp

<div style='font-weight: bold; margin: 0 0 10px 0;'>View All Signatures</div>

<table>
    <tr>
        <th>ID</th>
        <th>Session ID</th>
    </tr>
    <?php 
        foreach( $unsigned_images as $unsigned_image ){

            echo "<tr>";
                echo "<td>{$unsigned_image['UnsignedImage']['id']}</td>";
                echo "<td>{$unsigned_image['UnsignedImage']['session_id']}</td>";
            echo "</tr>";
        }
    ?>
</table>

我的数据库中有unsigned_images表
当我访问http://somedomain.com/unsigned_images/index/时，它会输出错误。
当我只使用var $ useTable = false;在模型中，没有打印错误。

非常感谢您的帮助！ :)
