Attachment_fu error

I have of the photos to associate to locations (photo belongs_to
location) , I am creating to them with attachment_fu and reorganized
with mini_magick. (you see file attached).
The problem verification when submit a new photo: it gives back an error
to me saying to me that the title it is along beyond 80 characters, even
if is inferior.


but I can add ulteriors fields to the table, besides those of default
from attachment_fu?
The " title" and " description" they remain NULL after every insertion
even if set up.
