Traceback is showing that you have a pre_save handler being called, and it
is that pre_save handler that is running into trouble. Specifically it's
having trouble with an attempt to do:
re.findall('\d+$', obj.slug)
obj.slug is going to be the problem here, as that's the only variable on
that line. Most likely you've got an object with no slug, meaning you're
passing None to that re.findall, which would result in the exception you
note. Did you create an object with no slug (you've defined it with
blank=True, null=True, so you've allowed for no value in the model
definition) but then not allow for that possibility in the pre_save handler?
