I'm trying to modify product images when a user marks a product as "sold" and I am able to modify the original image file successfully, but when I try to reprocess the thumbnails, my ImageMagick modifications don't stick. Here is what I've got going so far: def before_save if self.sold_changed? && self.sold? for photo in self.photos imagelist = Magick::ImageList.new imagelist.read(File.join(RAILS_ROOT, "public", photo.public_filename), File.join(RAILS_ROOT, "assets", "sold.png")) imagelist.flatten_images.write(photo_file) photo.save! end end end Does anyone know why calling 'photo.save!' would discard my ImageMagick changes? When I try the same function without calling photo.save!, my original image is modified exactly as I intend but the thumbnails are not updated. If anyone has a suggestion, please let me know. Thanks in advance!
