Active record duplication and save failure

I have this error: Errno::ENOENT in PicturethingsController#update_profile.

I’m trying to duplicate the standardpicture record and save that to
@character.profilepicture. I also can’t get @character.profilepicture to
save to the database (I know from checking after entering the rails

Here is the offending method:


def update_profile
  @character = Character.find_by(callsign: params[:callsign])
  standardpicture = Picturething.find_by(id: params[:picid])
  @character.profilepicture = standardpicture.dup!
  @character.profilepicture.picture = 

respond_to do |format|
format.html do
redirect_to @character.sociable


has_many :standardpictures, class_name: "Picturething",
                            inverse_of: :character,
                            foreign_key: "character_standard_id",
                            dependent: :destroy
has_one  :profilepicture,   class_name: "Picturething",
                            inverse_of: :character,
                            foreign_key: "character_profile_id",
                            dependent: :destroy

Is that all it says? Look in the log file to see if there is more.
It should tell you which line it failed on and I would have expected
some indication of the file it was looking for.

If not then simplify the method till you work out exactly which
statement is causing the problem.

As a thought, does the picture have an attached file or something like
that? Is the dup trying to do something with the file?
