ruby on rails - Ancestry gem: return only last child in threads -


the ancestry gem has lot of methods navigate tree structure. can model.roots show root elements etc. how opposite? - return newest child each tree structure.

i thought adding column model (latest/boolean) , logic after save filters etc. feels bit clumsy. :/

best regards. asbjørn morell

maybe can hack class#inherited hook, updating attribute of parent model on creation of new subclass:
