I am using Paperclip with AWS in my rails app. I have a model that holds the image:

class PaperclipFile < ActiveRecord::Base
  before_validation :parse_image

  belongs_to :attachment

  attr_accessor :base64_attachment

  has_attached_file :image, preserve_files: false
  validates_attachment :image, presence: true 
  do_not_validate_attachment_file_type :image

  private
    def parse_image
      return unless base64_attachment
      image = Paperclip.io_adapters.for(base64_attachment) 
      image.original_filename = "img_#{SecureRandom.urlsafe_base64}.jpg" 
    end
end

Basically I can pass an image in base64 and it processes and stores it correctly on S3. The issue is when I do .destroy

p = PaperclipFile.first
p.destroy

After that the record is gone from the DB but the file is not destroyed from the bucket. I don't get any errors so it doesn't look like it's trying at all.

The output is:

2.4.0 :005 > PaperclipFile.first.destroy
  PaperclipFile Load (0.8ms)  SELECT  "paperclip_files".* FROM "paperclip_files" ORDER BY "paperclip_files"."id" ASC LIMIT $1  [["LIMIT", 1]]
   (0.2ms)  BEGIN
  SQL (0.7ms)  DELETE FROM "paperclip_files" WHERE "paperclip_files"."id" = $1  [["id", 2]]
   (4.1ms)  COMMIT
 => #<PaperclipFile id: 2, attachment_id: 2, created_at: "2017-04-03 04:02:11", updated_at: "2017-04-03 04:02:11", image_file_name: nil, image_content_type: nil, image_file_size: nil, image_updated_at: nil> 
2.4.0 :006 > 

For the record I use Ruby 2.4, Rails 5.0.2 and as for the gems they look like this:

# Attachments
gem 'paperclip'
gem 'aws-sdk', '~> 2.3'

Thanks!
