Thanks Sergio.
But I've already tried using "to_label" but it didn't make a
difference. And after reading our link I realized it shouldn't make
a difference because I'm already using ":name" in every table already.
I think I just need to find a way to turn a "has many" foreign key
into a link. something like:
def kids
collect.link(kids_m).join(",")
end
but, of course this doesn't work because I'm still a ruby novice.
