Question

我安装了carrierwave和minimagick，我试图调整图像大小，如果它的肖像或它的风景，香港专业教育学院遵循运载波文档，但有些东西不起作用，它创建了肖像和风景图像。我现在已经玩了一段时间了，我想出了所有想法！任何想法都会受到赞赏。

这是我的代码my：uploader.rb

class CoverUploader < CarrierWave::Uploader::Base
      include CarrierWave::MiniMagick

      storage :file
      # storage :fog

      def store_dir
        "uploads/#{model.class.to_s.underscore}/#{mounted_as}/#{model.id}"
      end

      version :landscape, if: :is_landscape?


        version :landscape do
        process resize_to_fit: [@land_height, 250]
      end

      version :portrait, if: :is_portrait?


        version :portrait do
          process resize_to_fit: [250, @port_width]
        end


      process :store_dimensions

      def extension_whitelist
        %w(jpg jpeg png)
      end


      private

      def store_dimensions
        if file && model
          model.width, model.height = ::MiniMagick::Image.open(file.file)[:dimensions]
        end
      end

      def is_landscape? picture
        image = MiniMagick::Image.open(picture.path)
        image[:width] > image[:height]
        width = image[:width]
        aspect = image[:width] / image[:height].to_f
        @height = aspect * width
      end

      def is_portrait? picture
        image = MiniMagick::Image.open(picture.path)
        image[:width] < image[:height]
        height = image[:height]
        aspect = image[:width] / image[:height].to_f
        @width = height / aspect
      end
    end

所以这是创建3张图片而不是2张。

提前致谢！

这里只是粗略猜测：你用相似但不同的块覆盖version，而省略了你的条件。清理它。

version :portrait, :if => :is_portrait? do
  process resize_to_fit: [250, @port_width]
end

version :landscape, :if => :is_landscape? do
  process resize_to_fit: [@land_height, 250]
end

Carrierwave创建所有版本的图像
