Rails - Jun 2008 - How to define routes for resource that belongs to multiple resources?

Say I have resource comment that belongs to resources post and blog. I
know that to nest comment into say, post would look like this:

map.resources :posts do |post|
post.resources :comments
end

However, if I wanted :comments to also belong to :blogs, how would I
do that?

Actually I just read through that and while it''s useful, I still want
to know the syntax for defining such relationships.
