Changing models in django leads to a broken database?

Question

I added and removed the fields in the models.py file, and then ran manage.py syncdb. Usually I have to exit the shell and reload it before syncdb does anything. And then even after that, I get errors when trying to access the admin pages, it seems that some of the new fields that I added are still not showing up in the model:

Caught an exception while rendering: no such column: mySite_book.Title
