Carrierwave在創建版本後存儲原始文件

Question

我有ImageUploader類，我想在保存特定版本後將圖像的原始大小保存爲原始圖像。幫我解決這個

上傳

class ImageUploader < IconBase 
process :resize_to_fill => [490,68] 

version :normal do 
    process resize_to_fill: [245,34] 
    def full_filename(for_file = model.logo.file) 
    "avatar1.png" 
    end 
end 

def filename 
    "avatar.png" 
end 
end 

Answer 1

您的原稿尺寸不保存，因爲你在你上傳有process :resize_to_fill => [490,68]。爲了保持原來的大小，你可以把這個變成另一個版本，那麼你的主圖像會留unproccessed，像這樣：

version :large do 
    process :resize_to_fill => [490,68] 
end 

那麼你就必須：

uploader.url  # original image 
uploader.large.url # [490,68] version 
uploader.normal.url # [245,34] version
