Carrierwave: How to remove container directories when deleting a record

When deleting a record in your Rails app, Carrierwave automatically takes care of removing all associated files.
However, the file's container directory will not be removed automatically. If you delete records regularly, this may be an annoyance.

Here is a solution which was adapted from the Carrierwave GitHub wiki and cleans up any empty parent directories it can find.

Copy
class ExampleUploader < CarrierWave::Uploader::Base storage :file after :remove, :remove_empty_container_directory def store_dir # You implemented this in your uploaders already. end def remove_empty_container_directory(dir = store_dir) return unless Dir.empty?(dir) Dir.delete(dir) remove_empty_container_directory(File.dirname(dir)) end end

I suggest you also structure your file system for performance.

Does your version of Ruby on Rails still receive security updates?
Rails LTS provides security patches for old versions of Ruby on Rails (3.2 and 2.3).
