I'm having problems with get_absolute_url not working.
It works fine on my development site, but when I tried to deploy it,
it fails, and I can't figure out why
I'm using the "basic.blog" app
>>> post = Post.objects.published()
>>> p = post[0]
>>> print p.get_absolute_url()
Traceback (most recent call last):

line 198, in _get_urlconf_module

ValueError: Empty module name
I wondered about the return settings.ABSOLUTE_URL_OVERRIDES.get() in
the call stack. This is set to empty
>>> print settings.ABSOLUTE_URL_OVERRIDES
{}
(the default), so I'm not sure why it's there.
The exact same code running on another machine works fine:
In [13]: print p.get_absolute_url()
/blog/2009/mar/13/hello-0/
Two questions:
1. What does "ValueError: Empty Module Name" mean?
2. What environmental factors could make a simple get_absolute_url
method stop working? It's defined like this?
@permalink
def get_absolute_url(self):
return ('blog_detail', None, {
'year': self.publish.year,
'month': self.publish.strftime('%b').lower(),
'day': self.publish.day,
'slug': self.slug
})
