解決
class User < ApplicationRecord include ImageUploader::Attachment.new(:icon_image) end image_io = URI.parse("https://path/to/image.jpg").open image_uri.basename # filename image_io.size # file size MIME::Types.type_for(image_uri.to_s).first.content_type # extentions user.icon_image.replace(image_io) note
replaceではエンドポイント(アクセスURL)を変えずに、画像のみ変える。
