I think I might be able to spot where the problem is. Try running
pychecker on your app folder, rather than models.py.
Let's assume your app is called myapp, so you have a directory
structure something like this:
myapp/
-- __init__.py
-- models.py
-- views.py
-- tests.py
(et cetera)
If pychecker were doing 'import myapp', then the models module would
be accessible from 'myapp.models'. Therefore, models_module's __name__
attribute would be 'myapp.models', and the code would run fine;
'myapp.models'.split('.') would return ['myapp', 'models'], and the
[-2] index of that list would be 'myapp'.
However, because you're running pychecker directly on the models.py
file, its __name__ attribute is just 'models', which raises an error
in the Django code because 'models'.split('.') returns ['models'] --
this has no [-2] index, hence the exception.
Just try running pychecker on the 'myapp/' folder (if possible), and
see if that fixes the problem.
