Ruby on rails 使用Carrierwave，我想根据上传照片的类型将照片调整为不同的大小

我有一个用户模型和一个帖子模型。用户的照片将调整为小缩略图，帖子的照片将调整为大缩略图

version :smallThumb do
     process :resize_to_fill => [100, 100]
   end

   version :largeThumb do
     process :resize_to_fill => [200, 200]
   end

---

我如何告诉carrierwave为上传的照片选择哪个尺寸？对于所有上传，它会同时调整大小吗？

您可以创建两个单独的上传器型号。看起来像这样：

profile_uploader.rb

class ProfileUploader < CarrierWave::Uploader::Base

  include CarrierWave::RMagick

  storage :file

  version :thumb do
    process :resize_to_fill => [200, 200]
  end

end

class AttachedUploader < CarrierWave::Uploader::Base

  include CarrierWave::RMagick

  storage :file

  version :thumb do
    process :resize_to_fill => [100, 100]
  end

end

class ProfileUploader[200200]
结束
结束

atached_uploader.rb

class ProfileUploader < CarrierWave::Uploader::Base

  include CarrierWave::RMagick

  storage :file

  version :thumb do
    process :resize_to_fill => [200, 200]
  end

end

class AttachedUploader < CarrierWave::Uploader::Base

  include CarrierWave::RMagick

  storage :file

  version :thumb do
    process :resize_to_fill => [100, 100]
  end

end

类AttachedUploader[100100] 结束 结束 user.rb

class User < ActiveRecord::Base

  mount_uploader :profile, ProfileUploader

end

class用户

post.rb

class Post < ActiveRecord::Base

  mount_uploader :attached, AttachedUploader

end

class Post
