Javascript 每次在db表中插入记录时更新CakePhp视图

我正在制作一个应用程序，可以通过浏览器远程查看记录和报告。我使用cakePHP使应用程序及其工作正常，但我有一个小问题，因为应用程序不做任何插入，只是读取数据，我希望当用户打开视图并在表上插入记录时，它应该更新所有打开的客户端，而不是用户刷新页面以获得新记录。 是否有一个真正有效的cakePHP websocket插件？ 我们的Web主机不允许安装程序或添加apache模块，因此nodejs或类似的解决方案在这里不适用

我正在寻找一个纯粹的php和javascript实现，其中 只需将您的应用程序文件上载到Web服务器和所有内容 跑。你不必在apache上运行、安装附加程序或进行任何配置或诸如此类的操作。。。上传文件后

下面是我的一个控制器（BooksController.php）中的一个函数，它将数据检索到视图中

public function list_books()
  {
    $this->Books->recursive = 0;
    $this->paginate = array('order' => array('Serial_No' => 'DESC'));
    $this->set('All_Books', $this->paginate());
  }

这是我的一个视图（list_books.ctp），它在分页的表中显示数据

<div class="row-fluid">

    <div class="span12">
        <?php echo $this->Session->flash() ?>   
        <h4><?php echo __('All Books') ?></h4>
        <hr>               
                    <table class="table table-bordered">
            <thead>
                <tr>    <th><?php echo __('Serial No') ?></th>
                    <th><?php echo __('Title') ?></th>

                </tr>
            </thead>
            <tbody>
                <?php foreach( $All_Books as $book ){ ?>
                <tr>
                    <td><?php echo $this->Html->link(__($book['Book']['Serial_No']),'/books/view/'.$book['Book']['Serial_No']) ?></td>                                         
                                        <td><?php echo $book['Book']['Title'] ?></td>

                                        <td><?php echo $book['Book']['Available'] ?></td>

我可以在视图、控制器或模型上添加什么，以使视图自动更新？

---

这可以通过使用ajax实现吗？

您可以使用ajax轮询器，或者（HTML5）WebSocket（例如使用）进行推送通知。

您已经提到了，ajax。这是完成类似任务的最简单的方法，只需通过AJAX在后台进行检查，必要时重新加载页面，或者再次使用AJAX请求仅更新受影响的部分

当然，根据数据量的不同，您可以直接加载数据，而不是先检查更新

更新我误解了这个问题，如果插入/udpate是从外部来源进行的，而您在评论中没有直接控制，那么我唯一能想到的检查是否需要更新视图的选项就是检查

更新时间

（仅适用于MyISAM），用于更新可检查的自定义信息架构，或计算行数，但后者仅包括插入

所有方法都将在特定视图的控制器操作中获取比较值（更新时间或行计数），并将该值传递给视图，然后在AJAX调用中使用该值。AJAX调用调用一个控制器方法，将传递的值与当前时间/计数值进行比较，以确定是否需要更新

请注意，这些示例未经测试

信息模式 最简单的方法是检查

UPDATE\u TIME

信息模式，但是如上所述，这只适用于MyISAM表：

我没有对cakephp（web应用程序）进行任何更新或插入，所以这仍然有效吗？“Cache:：write（'model_last_update_books'，time（））；”对不起，我误解了你的问题。不，在这种情况下，这将不起作用，因为

afterSave

回调仅在模型保存时触发。您是否对进行实际插入/更新的应用程序有任何影响？例如，您是否可以让它插入/更新其他数据，或者如果它运行在同一台服务器上，是否可以将数据写入文件系统？如果没有，插入/更新是否包括创建/修改日期？我无法访问该系统，它是一个桌面应用程序不同用户的pc和我们应用程序服务器上的服务器，但它不会在所有表上保存修改日期和时间，我们需要的大多数数据都在没有修改日期和时间的表中我明白了。。。您正在使用哪个DBMS（版本和存储引擎）？这是一个固定的需求，还是您希望支持不同的DBMS？我们使用Mysql以及innodb和myisam表。我们无法更改，因为桌面系统无法支持其他dbms。
