Rails4 + Paperclip (unable to clone from model)

Question

Using Rails 4.0.2 and paperclip 3.5.3

I want to be able to clone the same model (Event) for any given dates that the user puts in the form. So if I want to have events day x, x+1 and x+2, I'll need to copy the paperclip attachment (which happens to be an image) over to the x+1 and x+2 events.

In theory, it should be enough to do something along the lines of

def create

respond_to do |format|
  if @event.save
     dates.each do |date| #the date var comes from another place, redacted for clearness
       event = @event.dup
       event.photo = @eevnt.photo
       event.save
     end
  end
end

But it doesn't.

It somehow marks the paperclip attachments for deletion.

Here's a copy of the log:

Has this happened to anyone before?

Any input on why doing it from the console works but I can't pull the-same-stunt from a controller?

Have you tried using Event.new instead of @event.dup ? Something along the lines of:

event = Event.new(@vent.attributes.except('id', 'photo_file_name', 'photo_content_type', 'photo_file_size', 'photo_updated_at')) # And any other attribute you don't want to copy
event.photo = @event.photo
event.save
