HI mates
I am trying to sort an array on 2 criterias , one is just in memory accessor, other is a record attribute :
I have the following User model :
class User < ActiveRecord::Base # name is an attribute in the table .... attr_accessor :current_distance .. end
In my controller, I calculate current_distance for each customer, and set user.current_distance , but don't save the record...
then get the following array : all_users => [#<User id: 1, name: "Alan", created_at: "2008-09-11 14:30:38">, #<User id: 2, name: "Bill, created_at: "2008-09-11 14:30:38">, #<User id: 3, name: "John", created_at: "2008-09-11 14:30:38">, #<User id: 4, name: "Michael", created_at: "2008-09-11 14:30:38">]
that I can sort easily using all_users.sort_by {|item| item.send 'current_distance' }
obviously, I cannot use all_users.sort_by {|user| user[:current_distance] } ... but I can use all_users.sort_by {| user> user[:name] }
my issue is trying to sort_by both criteria 1st on current_distance ASC, and 2nd on name DESC
any enlightment ?
thanks for your help
