大家好，我正在使用 Cakephp 2.x，我需要为每个单独的事件输出个人用户的评论。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，并希望允许用户在每个事件 view.ctp 上发布和查看评论。如果有人可以提供任何开始提示来实现此功能，将不胜感激。
我试图在事件 view.ctp 中输出评论模型索引表，但该表没有填充数据库中的评论，但评论 view.ctp 实际上用评论填充表。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">

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