The addition to the paragraph explains this well, thanks. (Incidentally however, is it possible to use Elixir with SQL views as well as tables? If so, that would be one workaround for these rare cases.) > > "Plain SA with scoped_session.

No sense duplicating. I definitely see your point about not wanting to duplicate existing information, but I think there's definitely a danger of the move to SQLAlchemy meaning that there's less documentation on how to get started than there was with SQLObject. I think "Defining Your Model" should still be a Turbogears-specific piece of documentation, which refers to SA/Elixir docs for elaboration. I appreciate that it may fall outside the scope of the doc you have here, but I think it's important for such a doc to exist /somewhere/ within the TG docs. I don't think having to run all over the web to find out how to use this thing is a good idea! As an aside, one of the reasons I've read for wanting to move to SA is that the documentation is superior to those for SO, which I can't argue with. However, I would argue that the Elixir docs are not as easy to use as the SO docs, so moving to SA and recommending Elixir on top is not really beneficial from an ease-of-use point of view. I don't know if others would agree however.
