Yeah I deleted that post immediately after because that selects child.name. Something like :select => "mothers.name AS mother_name" would probably work, but just ugly AND then you'd need a mother_name virtual attribute in the Child model, making things rather needlessly horrific. I really can't think of a good way (without raw SQL) to do this in one query either.
