I have the same code, I think..., and I doesn't get that error.
Try to put comments in the whole method save() or in the line 76 so that
we can see where is the problem...

You have only that mistake in the code you've attached...
Your models.py works on my system.

The imported name 'markdown' should be a function, yet python thinks
it's a module. What is it?
Try importing markdown and running the above snippet outside of django
in a python shell. Does that work?

I'll bet money that you have this:
import markdown
When the book tells you to do this:
from markdown import markdown
There's a very important difference.

But when I changed the import line to: from markdown.markdown import
markdown
then THAT error disappeared.
I looks that I made something wrong when I installed the markdown
files.
In '/usr/lib/python/site-packages' I have a link:
markdown -> /home/markku/django/markdown-1.7
and in '/home/markku/django/markdown-1.7' is file a file
'markdown.py', containing a function 'markdown'. So the same name
'markdown' is in three places!
