Ok, I guess that my problem is two fold. The first is that the generated SQL tried to create two tables called polls_polls. And I see now that adding
class META: module_name = 'tigger' to the Tigger class resolves that issue. My second issue was in thinking that the table generated from the derived class would have a relationship with the table generated from be base class. And the documentation that you pointed my towards shows how Django works in this case. I guess that I was still thinking in terms of SQLObject instead of Django. Thanks for the clarification! - Peter
