Cakephp 如何回应用户'；个别活动的评论

大家好，使用Cakephp 2.x的所有Iam，我需要为每个事件输出各个用户的评论。每个用户都有许多事件和许多评论。我有事件、评论和用户模型，希望允许用户在event view.ctp上发布和查看评论。如果有人能给出实现此功能的起始提示，我们将不胜感激

我曾尝试在events view.ctp中输出comments model index表，但该表未填充来自数据库的注释，但comments view.ctp实际上使用注释填充了该表。我使用了$this->loadModel（'Comments'）；事件控制器中的函数

<div class="events view">
    <?php echo $this->Html->css('viewevent'); ?>
    <?php echo $this->element('maintitlegen'); ?>

    <div style="padding-top: 160px">
    <h2><?php  echo $event['Event']['name']; ?></h2>
    <dl>

        <dt><?php echo __('Event Image'); ?></dt>
        <dd>
            <?php echo $this->Html->image('/uploads/event/filename/thumb/small/'.$event['Event']['filename']); ?>
            &nbsp;
        </dd>


        <dt><?php echo __('Date'); ?></dt>
        <dd>
            <?php echo h($event['Event']['date']); ?>

我认为可以安全地假设您的注释表至少包含以下列：

• 身份证
• 用户id
• 事件id
• 注释（或名称）

在OP中显示的视图是events.view方法的视图。但不显示偶数模型或控制器。因此，我不确定您是否需要事件控制器的帮助，或者您是否正在尝试在用户控制器中显示事件数据。获取OP中显示的视图的所有注释的方法是从模型中提取所有注释，如下所示：

$this->set('comments', $this->Event->Comment->find('all', array('conditions' => array('event_id' => $event_id))));

如果您希望用户数据与它一起显示，您需要设置recursive=1或编写一个联接来联接用户数据。

可以方便地为您的用户查看您的模型，但要检查，只需打印（$event），查看其中是否包含用户数组，如果包含，很好，您就快到了，如果没有，则说明您的模型设置错误。如果您打印r（$event['User']），会发生什么；张贴您的模型和控制器，这将使它更容易帮助。我认为这里的视图不是问题。我已经在这里发布了我的用户模型，这是我的打印输出（$event['user']）；-数组（[id]=>19[name]=>Daniel Toppin[username]=>Daniel[email]=>daniel@gmail.com[密码]=>8ecf7bb874637ae1617570e95caf10ed183bbef3[角色]=>[文件名]=>[目录]=>[模拟类型]=>[文件大小]=>[创建]=>2012-12-10 22:20:26[修改]=>2012-12-10 22:20:26）这将是您的事件模型和控制器，我们需要看到，以帮助，所以张贴。如果您只是使用蛋糕烘焙控制台来构建模型、控制器和视图，那么蛋糕将自动在Event view.ctp文件中显示每个事件的注释。这是假设您的数据库结构是正确的（即，Comments有一个user\u id和一个event\u id字段，Events有一个user\u id字段）。您是从使用蛋糕烘焙控制台构建应用程序开始的吗？
