CakePHP: 3 levels deep associations not working properly - php

Question

In my app a user has a profile and a user can post comments and posts.
When viewing a list of comments for a post I want to show the name of the person that posted the comment. I have tried the following:
<?php if ( ! empty($post['Comment']) ): ?>
<ul>
<?php foreach ($post['Comment'] as $comment): ?>
<li id="comment-<?php echo $comment['id']; ?>">
<h3><?php echo $this->Html->link($comment['User']['Profile']['firstname'] . ' ' . $comment['User']['Profile']['lastname'], array('controller'=>'profiles','action'=>'view','userName'=>$comment['User']['username'])); ?></h3>
<?php echo $comment['content']; ?>
<?php echo $comment['datetime']; ?>
</li>
<?php endforeach; ?>
</ul>
<?php else: ?>
<p>No comments...</p>
<?php endif; ?>
But I get the following error: Undefined index: User [APP/View/Posts/view.ctp, line 37]
Any ideas on how to fix the issue?
I have the following for the controller method:
function view ( $id = null, $slug = null )
{
$post = $this->Post->find('first',array('contain'=>array('Comment','User'=>array('Comment','Profile')),'conditions'=>array('Post.id'=>Tiny::reverseTiny($id))));
if (!$post)
{
throw new NotFoundException('404');
}
else if($post['Post']['status'] == '0') // 0=draft 1=open 2=open
{
if($post['Post']['user_id'] == $this->Auth->user('id'))
{
$this->Session->setFlash('Your post has NOT been published yet');
}
else
{
throw new NotFoundException('404');
}
}
if (Inflector::slug($post['Post']['title']) != $slug || $slug = null)
{
$this->redirect(array('id'=>Tiny::toTiny($post['Post']['id']),'slug'=>Inflector::slug($post['Post']['title'])));
}
$this->set(compact('post'));
}
The model associations should all be correct as I can see the comments fine and see the profile info for the post itself, it's just the comments that don't show the profile info.
Thanks to all who can help.

You're setting $post['Comment'] as $comment in your foreach, whilst your user data isn't in $post['Comment']['User'] but in $post['User'], so your call with $comment['User'] won't work, since that index does not exist.
Use debug($var) in the future so you can see how your array structure looks like at any given moment.
