Hello,
I'm trying to learn Django from the book "Practical Django Projects 2nd
Edition"
I'm using Django 1.3.1 and Python 2.7.2 on Windows 7
Also I'm using Eclipse Indigo with pydev
The current project I'm working on is to create a Weblog called coltrane.
coltrane is an application that exists in a project called
"cmswithpythonanddjango"
Inside the models.py is a class called Entry which holds the fields used to
Enter a weblog entry.
When I go to localhost:8000/admin/ I get the option to add and Entry.
I can select this option fill out sample data, but when I try to save it.
I get the following error.
AttributeError at /admin/coltrane/entry/add/
'Entry' object has no attribute 'pubdate'
There is a field called pub_date in Entry
It's as if I have made a typing error somewhere and typed pubdate instead of
pub_date.
Below is the models.py, views.py , url.py , and admin.py files

I can't think of anywhere else the problem could be other than in one of
the above files.
If somebody knows what the problem is I would be very grateful if they
could tell me what it is.
Failing that, I would appreciate any suggestion of where else I could look.
