i have a function that i wanna use in different models and i wanna do it
DRY.
so my best option as i see it is to include a module i made (that is in the
lib/ directory) in the model.
my code basicly looks something like this (for testing purpose, i didn't
implement my function yet)
lib/model_helper.rb
module ModelHelper
def bla
puts "hello world"
end
end
app/models/test.rb
class Test < ActiveRecord::Base
include ModelHelper
end
now the weird part is, when i try to do this in rails 2.2 it works but when
trying to do this in rails 3.0.0 it doesnt.
why is that?
is there any way of doing it in the newest version of rails?
