Preventing Paperclip from deleting/overwriting attachments on update

Question

I\'m having a hard time figuring out how to prevent Paperclip from deleting the old version of an attachment (image).

I have a model, Site, which has an attachment,

Answer 1

lib/paperclip_monkey_patch.rb:

module Paperclip
  class Attachment
   def clear
    # nop
    #raise "hell"
    # op
    instance_write(:file_name, nil)
    instance_write(:content_type, nil)
    instance_write(:file_size, nil)
    instance_write(:updated_at, nil)
  end
 end
end

Then add this line at the top of any file that deleted attachments:

require 'paperclip_monkey_patch'
