With ActiveRecord, how do I sort results using associations?
For example, I have
class Roster < ActiveRecord
# name => text
class Member < ActiveRecord
# zip_code => integer
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??
