Any chance of augmenting it to include the ActiveMapper code? I know ActiveMapper isn't final yet, but it would be wonderful to see how to get that working... On the positive side, it wouldn't be that hard to create a TG plug in that automatically commits the unit of work after a successful request... And I promise to get a SqlAlchemy based Identity Provider going soon... Karl, that’s a fantastic overview. Any chance of augmenting it to include the ActiveMapper code?

Which means if it was integrated with TG I could use TG now. I like the way SQLAlchemy does things and it already has Oracle support. Which means if it was integrated with TG I could use TG now.

I maintain that fastdata support should be rather simple and admit to never having used CatWalk or ModelDesigner. I’ve written a preliminary guide to using SQLAlchemy with TurboGears:

Then ignore what I said ;-) I've been working with 0.8.8 until 0.9 comes out. Sounds like there's a great deal of momentum behind 0.9. I'm definitely looking forward to exploring the new features.

It's also worth noting that TurboGears will continue to have one recommended way of doing things for which a solution is provided.

Are there any plans for integrating SQLAlchemy or other database layers into TurboGears? The model level definitely seems to be the least tightly coupled of all the components in TurboGears, so it *seems* like it would be straightforward to have pluggable models like we have pluggable templates. Just my $.02. From what I’ve seen, SQLAlchemy looks good, mainly because it seems to give more of the power of SQL than something like SQLObject.
