Carrier Fog Aws - Files are automatically disappearing from S3

Question

The files uploaded succesfully using fog to s3 on carrierwave seem to be disappearing automatically.How do I prevent this from happening. The fog public setting is set to true.

Answer 1

For some reason, Carrierwave deletes files not only when the model is deleted, but also when it's updated, even if you don't touch the mounted uploader field. There is supposed to be a config setting remove_previously_stored_files_after_update that when set false, prevents this from happening, but I haven't had any luck setting it false – it still deletes my files on model update.

Answer 2

Inside your uploader class you can modify the #remove! method.

class FileUploader < CarrierWave::Uploader::Base

  #...

  def remove!
    # do some stuff to confirm that you want the file removed,
    # otherwise return.  You have access to model record as 'model'
    super
  end

end
