Don't do this in the save method. Instead, define a custom upload
handler for the picture element.
import os.path
def pet_picture_upload(instance, filename):
name, ext = os.path.splitext(filename)
return '/usr/django/images/%s%s' % (instance.pk, ext)
class Pet(models.Model):
name = models.CharField(max_length=64)
picture = models.ImageField(upload_to=pet_picture_upload)
