At the end of chapter 4 there is a challenge:

You may have noticed that I left the commentstable out of the tutorial for this chapter.This was to allow you to try
building a “has many”relationship for the postsand commentstables on your own.In this exercise,associate
comments with posts by using the appropriate relationship,and test the association using the scaffold.Be sure to
check for errors by running the controller from both ends of the association.

Don’t forget to add the Belongs To relationship. In a one to many relationship, or $hasMany, you need to specify this way: Posts $hasMany comments but comments $belongsTo posts! So i would then have:

Model: post.php

class Post extends AppModel {
  var $name = 'Post';
  var $belongsTo = array(
    'User'=>array(
      'className'=>'User',
      'foreignKey'=>'user_id',
      'conditions'=>null,
      'fields'=>null
    )
  );
  var $hasAndBelongsToMany = array('Tag');
  var $hasMany = array('Comment');
}
?>

Model: comment.php

class Comment extends AppModel {
  var $name = 'Comment';
  var $belongsTo = array('Post');
}
?>
