Title
Body
In my model Shop I'm saving image url in logo_ori and use that to make thumbnails using before_update . # shop.rb before_update :run_blitline_job private def run_blitline_job # uses logo_ori to make thumbnails end However I found out that when I'm saving other attributes (eg: editing shop's profile in a form) it also runs before_update . How do I confine its execution when only logo_ori is saved? I've tried this : before_update :run_blitline_job, :if => :logo_ori? but it still runs before_update if I already have logo_ori saved earlier.
