CakePHP containable order condition not working - cakephp

Question

I'm having problems with a very simple ordering query. I have a Post model and a Tag model with a HABTM relationship and am trying to return a list of all posts with a particular tag assigned to them, ordered by the date the post is created.
$this->set('data', $this->Post->Tag->find('all', array(
'conditions' => array('Tag.id' => 1),
'contain' => array('Post' => array(
'order' => 'Post.created_date desc'
))
)));
While this returns the list of posts, it is not sorted by date.
With debugging on, it looks like the following query is being used:
SELECT `Post`.`id`, `Post`.`title`, `Post`.`created_date`, `PostsTag`.`post_id`, `PostsTag`.`tag_id`
FROM `database`.`posts` AS `Post`
JOIN `database`.`posts_tags` AS `PostsTag` ON (`PotsTag`.`tag_id` = 1 AND `PostsTag`.`post_id` = `Post`.`id`)
Code for posts model:
class Post extends AppModel {
public $name = 'Post';
public $hasAndBelongsToMany = array('Tag');
}
Code for tags model:
class Tag extends AppModel {
public $name = 'Tag';
public $hasAndBelongsToMany = array('Post');
}
Any help on the issue would be much appreciated - I'm using CakePHP 2.1. if it makes any difference.

Answer 1

What about defining the order attribute in your Tag Model?
Like e.g.
var $hasAndBelongsToMany = array(
'Post' => array(
'order' => 'Post.created_date'
)
);

Answer 2

I don't think that the "order" should be inside of "contain".
Try with:
$this->set('data', $this->Post->Tag->find('all', array(
'conditions' => array('Tag.id' => 1),
'contain' => array('Post'),
'order' => 'Post.created_date desc'
)));
or just:
$this->set('data', $this->Post->Tag->find('all', array(
'conditions' => array('Tag.id' => 1),
'order' => 'Post.created_date desc'
)));
