Rails 6 - Shrine - ImageProcessing - 获取原始上传文件

Rails 6 - Shrine - ImageProcessing - Get Original Uploaded file

这是我的image_uploader.rb

require "image_processing/mini_magick"

    class ImageUploader < Shrine


    Attacher.derivatives do |original|
        magick = ImageProcessing::MiniMagick.source(original).saver(quality: 88)
        # generate the thumbnails you want here 
        { 
         thumb:  magick.resize_to_fill!(150, 150),
         medium: magick.resize_to_fill!(500, 500),
         large:  magick.resize_to_limit!(800, 800),
        }
    end


end

问题很简单,但我找不到答案是 Shrine 文档。我怎样才能得到原始照片?在 Rails 4 中很简单,我只要求 image_url(:original)

一些技巧:

我阅读了 mini_magic 并添加了类似这样的内容

 original: magick.resize_to_limit!(20000,20000),

如果不超过 20000x20000 尺寸,图像将不会更改 ...

好久没用神社了...

简单的怎么样

@image.image_url
