Datamapper deep relationships

I can't comment on that.

This shows a model called "Post" which has a "has_one" to "parent" and a "has_many" to "childrens". It doesn't show the relations between "parent" and "childrens", which is what is used when you specify "parent/childrens".

Second point is that in a relationship definition, "class" points the the model class the relationship is pointing to. Which in this example is the "Post" model itself?
