找不到PostsController:：index（）-CakePHP

我正在努力掌握cakephp。所以我从cakephp演示博客应用程序开始。我遵循了教程的前几个步骤，当我尝试加载posts控制器时，它会说

Missing View
Error: The view for PostsController::index() was not found.

Error: Confirm you have created the file: T:\Project Folders\NetBeans\cakeBlog\app\View\Posts\index.ctp

我在stackoverflow、cakephp论坛甚至Google群组中搜索了很多关于这一点的信息，但似乎没有一个解决方案对我有效。发布的大多数解决方案如下所示：

检查mod_rewrite是否已启用——是，我已启用它

检查是否将index.ctp命名为index.ctp而不是index.cpt、index.ctp或任何其他变体。-是的，我将索引放在app/views/Posts/index.ctp（使用netbeans向导）下面

使用标签而不是php短标签——我使用的是传统的标签

开发环境

Web服务器-WAMP 我创建了一个名为

cakeblog

的别名，并将其指向

cakephp\u文件夹/app/webroot/

cakeblog.conf

core.php

   <?php
    class Post extends AppModel {
        //put your code here
    }
    ?>

<?php

  class PostsController extends AppController {
    //put your code here
    public $helpers = array('Html', 'Form');

     public function index() {
        $this->set('posts', $this->Post->find('all'));
    }
     public function view($id = null) {
        if (!$id) {
            throw new NotFoundException(__('Invalid post'));
        }

        $post = $this->Post->findById($id);
        if (!$post) {
            throw new NotFoundException(__('Invalid post'));
        }
        $this->set('post', $post);
    }
}

?>

<!-- File: /app/View/Posts/index.ctp -->

<h1>Blog posts</h1>
<table>
    <tr>
        <th>Id</th>
        <th>Title</th>
        <th>Created</th>
    </tr>

    <!-- Here is where we loop through our $posts array, printing out post info -->

    <?php foreach ($posts as $post): ?>
    <tr>
        <td><?php echo $post['Post']['id']; ?></td>
        <td>
            <?php echo $this->Html->link($post['Post']['title'],
array('controller' => 'posts', 'action' => 'view', $post['Post']['id'])); ?>
        </td>
        <td><?php echo $post['Post']['created']; ?></td>
    </tr>
    <?php endforeach; ?>
    <?php unset($post); ?>
</table>

我能够启动该应用程序，我看到欢迎页面很好。我在startup.png中附加了它的快照

现在，让我粘贴代码，我只是从教程中复制粘贴的代码：

app/model/post.php

   <?php
    class Post extends AppModel {
        //put your code here
    }
    ?>

<?php

  class PostsController extends AppController {
    //put your code here
    public $helpers = array('Html', 'Form');

     public function index() {
        $this->set('posts', $this->Post->find('all'));
    }
     public function view($id = null) {
        if (!$id) {
            throw new NotFoundException(__('Invalid post'));
        }

        $post = $this->Post->findById($id);
        if (!$post) {
            throw new NotFoundException(__('Invalid post'));
        }
        $this->set('post', $post);
    }
}

将目录app/View/Pages/Posts/更改为app/View/Posts/

---

每个控制器都有自己的带有视图文件的目录。

视图文件存储在/app/View/中，以使用这些文件的控制器命名，并以其对应的操作命名。在您的示例中，Post控制器的“index（）”操作的视图文件通常位于/app/view/Posts/index.ctp中。

非常感谢。我想我一定是误读了教程。我现在觉得有点尴尬。但是，如果你正在学习新的东西，问一些简单的问题并不羞耻。好问题。“我仍然认为这值得一提”-是的，如果你正在编写教程，读者不希望必须访问教程才能了解你正在编写的内容。在你的岗位上提供一切，就像你所做的那样+1.
