Hi,
This is an issue which, I believe, is related to Ticket #10788
(http://code.djangoproject.com/ticket/10788).
The following code snippet used to work with Django 1.0.2, but with
the latest svn version the slug is not being set to the filename
produced by get_path because, as I understand it, get_path will not be
called until the instance is saved to the database.
def get_path(instance, filename):
salt = hashlib.sha1(str(random.random())).hexdigest()
name = hashlib.sha1(salt+filename).hexdigest()[:16]
return '%s.jpg' % (name)
class Photo(models.Model):
photo = models.ImageField(upload_to=get_path, blank=False)
...
slug = models.CharField(max_length=16, unique=True)
def save(self):
self.slug = self.photo.url.split('/')[-1:][0].split('.')[0]
super(Photo, self).save()
I could call instance.save() twice in my view to force it to use the
correct name, but this feels a bit messy to me. What's the best way to
get the correct value for the slug field prior to saving it to the
database, given that the filename is 'randomly' generated?
Cheers,
Andrew
