With ActiveRecord, how do I sort results using associations?
For example, I have
class Roster < ActiveRecord # name => text has_many :members end class Member < ActiveRecord # zip_code => integer belongs_to :roster end
I would like to generate a list of members, grouped by roster name, sub-sorted by zip code.
Something like this: Member.order("roster.name, zip_code").all
But I can't get the syntax quite right - I've played around with join and include - can anyone tell me the right syntax to use??
