attachment_fu: I just want an attachment

Take a look at this, a small helper I wrote for exactly this task, describtion in the rdoc: http://pastie.caboo.se/132853

put it in lib/has_image.rb and then write your model

class Product < ActiveRecord::Base   belongs_to :image   include HasImage   ... end

Forgot to mention, this assumes your image model is called "Image". Adjust the code accordingly if your Model is named differently
