I suspect that this is going to wind up trivial and I’m going to slap
myself in the head…
Suppose I have User and Comment AR classes.
User has_many :comments, Comment belongs_to :user
I want to do a User.find, which returns User objects in order of which
user has the most comments. I suspect that this involves renaming the
COUNT(*) results of a sub-select so that I can order by them.
