...and to be a little more concrete, at first glance the way I'd apply
that advice to your code example is to make a class that either
subclasses or wraps (via DelegateClass/SimpleDelegate) Array and adds
a #sub_total method, something like the following:
class Survey < ActiveRecord::Base
has_many :participants
...
def generate_reports
...
sub_total = ReportCollection.new(participants.reports).sub_total
...
end
class ReportCollection < SimpleDelegator
def sub_total
sub_total = 0
self.collect do |report|
sub_total = sub_total + report.score
end
return sub_total
end
end
end
