Currently there is no way to prevent admin from uploading file with the
same name (which will result in overwriting the previous file) (having
zillions of date based directiories is not a good idea).
The simplest solution would be to use primary key as the file name, but
when upload_to callable is called the instance doesn't have the primary
key yet.
{{{
class Gallery(models.Model):
name = models.CharField(max_length=255)
def image_upload(instance, filename):
return 'content/gallery/' + gallery.id + '/' + instance.id +
'.jpg' # extension can be retrieved from filename
class Image(models.Model):
gallery = models.ForeignKey(Gallery)
title = models.CharField(max_length=255)
image = models.ImageField(upload_to=image_upload)
}}}
The above results in creation of None.jpg file.
