[storm] How to define two Storm tables that reference each other

[Alec Henriksen]

Hello list,

I am defining my storm tables like this (in a file called objects.py):

class Article(object):
	"""
	This is a Storm table: articles
	"""
	__storm_table__ = "articles"
	id_ = Int(primary=True)
	url_id = Unicode()
	title = Unicode()
	tags = Unicode()
	author = Unicode()
	timestamp = Unicode()
	content = Unicode()
	comments = ReferenceSet(id_, Comment.article_id)
	comment_count = len(comments)
	ip = Unicode()
	active = Int()
	
			
class Comment(object):
	"""
	This is a Storm table: articles
	"""
	__storm_table__ = "comments"
	id_ = Int(primary=True)
	author = Unicode()
	article_id = Int()
	article = Reference(article_id, Article.id_)
	thread_id = Int()
	timestamp = Unicode()
	email = Unicode()
	website = Unicode()
	text = Unicode()

The problem is, obviously enough, I can't reference Comment.article_id
before I've defined Comment. I also can't switch the two classes around,
because both Comment and Article reference each other. Python gives me
this:

File "/var/www/alecwh/objects.py", line 34, in Article, referer:
http://localhost/
comments = ReferenceSet(id_, Comment.article_id), referer:
http://localhost/
NameError: name 'Comment' is not defined, referer: http://localhost/

So, does anybody have any recommendations for resolving this? Perhaps
I'm not thinking about this correctly. Thanks a lot in advance.
