Renaming uploaded files with Carrierwave

Question

I\'m using Carrierwave to upload files, and I have it working.

My issue is attempting to change the name of the uploaded file.

In the generated uploader.rb there

Answer 1

To just make the record.id prefix the filename you can do the following:

class MyUploader < CarrierWave::Uploader::Base

  storage :file

  def store_dir
    model.class.to_s.underscore.pluralize
  end

  def filename
    model.id ? "#{model.id}-#{original_filename}" : original_filename
  end

  def url
    "/#{store_dir}/#{model.id}-#{model.file_before_type_cast}"
  end
end
