alasanya biar ndak diulangi terus (NDT-bhs indonya DRY, alah :D) ,
soale ada kemunkinan belongs_to nya jd nambah
btw makasih pak, kodenya dah nyala he he
tapi jd bertanya-tanya, potongan kode itu kan ndak dimasukin ke dalam
def, kalo dimasukin gmn caranya, daku udah nyobain kayak gini, eh ndak
bisa, muncul error "undefined method `belongs_all' for Avatar:Class"
module CustomizeBelong
def belongs_all(elements)
elements.each do |e|
eval(%Q~belongs_to :#{e}_asset, :foreign_key
=>"#{e}",:class_name => "Asset"~)
end
end
end
class Avatar < ActiveRecord::Base
include CustomizeBelong
belongs_all ["hair","body","hand","shoes","face"]
end
hihi koq jd berexperiment ginih
