Subject: (SOLVED) Exception: 'Tag' must extend from ActiveRecord\Model' though it already does

Hi guys,

I have stumbled into a surprising issue. Trying to fetch posts (MySQL v5.1.49; PHP v5.3; PHP ActiveRecord v1.0) like so:

1 $posts = Post::find('all', array('order' => 'id desc'));

results in:

Fatal error: Uncaught exception 'ActiveRecord\RelationshipException' with message ''Tag' must extend from ActiveRecord\Model'

But class Tag definitely extends ActiveRecord\Model:

models/post.php

1 class Post extends ActiveRecord\Model {
2   static $has_many = array(
3       array('post_tag_relations', 'class_name' => 'Post_Tag_Relation'),
4       array('tags', 'through' => 'post_tag_relations')
5   );
6 }

models/tag.php

1 class Tag extends ActiveRecord\Model {
2   static $has_many = array(
3       array('post_tag_relations', 'class_name' => 'Post_Tag_Relation'),
4       array('posts', 'through' => 'post_tag_relations')
5   );
6 }

models/post_tag_relation.php

1 class Post_Tag_Relation extends ActiveRecord\Model {
2   static $belongs_to = array(
3       array('post'),
4       array('tag')
5   );
6 }

Changing the Post class to

1 class Post extends ActiveRecord\Model {
2   static $has_many = array(
3       array('post_tag_relations', 'class_name' => 'Post_Tag_Relation')
4   );
5 }

makes everything work out okay, but this isn't the sort of solution I'm looking for.

I feel like I'm messing up something simple, but no amount of digging has yet come to any avail. As ever, any input would be appreciated.
