I solved this another way, today. I move the file to it's new filename
in the save method of the model. It's not fully tested but seems to
work. In my case I use a slug field to create nice filenames.
def save(self):
if self.image:
import shutil
from os import path
from django.conf import settings
pathname, filename = path.split(self.image)
extension = path.splitext(filename)[1]
new_image = path.join(pathname, '%s%s' % (self.slug,
extension))
new_location = path.join(settings.MEDIA_ROOT, new_image)
old_location = path.join(settings.MEDIA_ROOT, self.image)
if new_location != old_location:
shutil.move(old_location, new_location)
self.image = new_image
super(Image, self).save()
