After updating to a Django revision post- , get_FIELD_url is broken for all FileField and ImageField uploads using an upload_to with date-based directory parts.
 updates get_FIELD_url to call field.get_filename on the DB-stored path. field.get_filename only uses the basename of its argument, and calls field.get_directory_name for the directory part. field.get_directory_name uses datetime.now() for interpolating the date parts into upload_to.
def get_directory_name(self): return os.path.normpath(force_unicode(datetime.datetime.now().strftime( def get_filename(self, filename): from django.utils.text import get_valid_filename f = os.path.join(self.get_directory_name(), get_valid_filename(os.path. return os.path.normpath(f)
This means that instead of returning a URL with the correct path that is stored in the DB, get_FIELD_url now returns a URL that always has the current date interpolated into it. For any file uploaded before today, that will be a broken link.
This is a showstopper bug; please revert  as quickly as possible.
