class objects. How do i do that in ruby?
Yes, you can. This is your program, refactored to do that (I've not tested it so excuse any typos):
class Data
attr_reader :a, :b
def initialize(a, b)
@a = a
@b = b
end
end
class A < ActiveRecord::Base
def fill_paths
@files.map |file|
Data.new(file, data_2('assume data2 is valid'))
end
end
end
#Controller
@paths = A.fill_paths
@paths.each do |path|
puts path.a
end
