How to delete the original files and keep only the versions using CarrierWave?

问题

I'm trying this but without luck.

class FileUploader < CarrierWave::Uploader::Base

  after :cache, :unlink_original

  def unlink_original(file)
    file.delete
  end

  .
  .
end

Figured it out.

There was a typo in the docs.

Fixed it with the following.

class FileUploader < CarrierWave::Uploader::Base
  after :store, :unlink_original

  def unlink_original(file)
    File.delete if version_name.blank?
  end
  .
  .
end
