Talking to myself again, I've changed the save method slightly:-
def save(self):
if not self.slug:
name = hashlib.sha1(str(random.random())).hexdigest()[:16]
self._my_filename = '%s.jpg' % (name)
self.slug = name
super(Post, self).save()
and added a blank=True to the slug field so that it only sets it on
the first save.
If there is a better way of doing all this, feel free to let me know.
If not, I hope this is of use to somebody.
Thanks for your pointers, Rajesh.
Cheers,
Andrew
