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

Here is the solution, how to change the name of the file, if store_dir already contains the file with the exact name:

  if File.exists?(Rails.root.join("documents/" + "#{file.filename}")) && !path.to_s.eql?(Rails.root.join("documents/" + original_filename).to_s)
    @name ||= File.basename(original_filename, '.*') + Digest::MD5.hexdigest(File.dirname(current_path)).from(25)
    "#{@name}.#{file.extension}"
  else
    "#{original_filename}"
  end

Note: Rails.root.join("documents/") is defined as my store_dir.

Hope it helps someone.
