Hi Chris,
The short answer is that I want to dynamically create classes/tables
Why?
and I want to implement multiple inheritance
That's fine, that's what mixins give you.
If you have more than one class with a __tablename__ in the class
hierarchy, then you'll get table inheritance, which may also be what you
want.
(simplified version: just
data and no overrides =>
What do you mean by "overrides"?
no diamond problem),
What do you mean by "diamond problem"? Python has a well defined MRO, if
that's what you're worried about...
so I need some extra
work like a extra tables for polymorphism.
What does polymorphism mean to you? SQLAlchemy handles most polymorphic
OR mapping quite gracefully...
I think it would be most
elegant to do this with metaclasses, but I am just experimenting until
now.
You come across as someone with a hammer desperately looking for nails
and frustrated when you find only screws ;-)
cheers,
Chris
