scott,

Actually I believe the syntax you suggested is what I first tried, and did not work, and caused the searching.

DataMapper is still somewhat young, so check the integration tests referenced in the post for the most recent developments.

This is very helpful, though I'm not too familiar with datamapper. I'm trying to see if it'll fit what I need.

Could this be expanded to the parent becomes,
has n, :children, :class_name => 'Node', :child_key => [:child_id]
has n, :parents, :class_name => 'Node', :child_key => [:parent_id ]

Something like that would work with activerecord, but, like I said I'm not too familiar.

Cheers

It looks more like a tree relationship then a parent/child relationship.
