How to echo Users' Comments for individual Events - cakephp

Question

Hi all Iam using Cakephp 2.x, I need to output individual users' comments for each individual event. Each user has many events and many comments. I have Events, Comments and Users models and want to allow users to post and view comments on each event view.ctp. If anyone could give any starting tips to implement this functionality it would be much appreciated.
I have tried to output the comments model index table in the events view.ctp, but the table is not populated with the comments from the database, but the comments view.ctp does in fact populate the table with the comments. I have used the $this->loadModel('Comments'); function in the events controller.
<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']); ?>
</dd>
<dt><?php echo __('Date'); ?></dt>
<dd>
<?php echo h($event['Event']['date']); ?>
</dd>
<dt><?php echo __('Time'); ?></dt>
<dd>
<?php echo h($event['Event']['time']); ?>
</dd>
<dt><?php echo __('Description'); ?></dt>
<dd>
<?php echo h($event['Event']['description']); ?>
</dd>
<dt><?php echo __('Dresscode'); ?></dt>
<dd>
<?php echo h($event['Event']['dresscode']); ?>
</dd>
<dt><?php echo __('Slogan'); ?></dt>
<dd>
<?php echo h($event['Event']['slogan']); ?>
</dd>
<dt><?php echo __('Price'); ?></dt>
<dd>
<?php echo h($event['Event']['price']); ?>
</dd>
<dt><?php echo __('Offers'); ?></dt>
<dd>
<?php echo h($event['Event']['offers']); ?>
</dd>
</dl>
<!--<?php foreach ($users as $user): ?>
<?php echo $user['Comment']['comment']; ?>

I think it is safe to assume your comment table has at least the following columns:
id
user_id
event_id
comment (or name)
The view you display in the OP is the view for the events.view method. But you do not show the even model or controller. So I am not certain if you need help with the events controller or if you are trying to display event data in the users controller. The way to get all of the comments for the view you show in the OP is to pull all of the comments from the model like so:
$this->set('comments', $this->Event->Comment->find('all', array('conditions' => array('event_id' => $event_id))));
If you want the user data to be displayed along with it, you will need to either set recursive = 1 or write a join to join the user data.
