Can I use it with scaffolding_extension ? I have a very complex legacy project I have mapped out quite nicely in ActiveRecord, and uses scaffolding_extensions. I'd like to add DRYSql to it even though it likely isn;t needed, just to start using it, but only want to do it if there;s not a ton of work to be done (because it works now, as is, but, of course, I;d like to learn a faster, simpler way!) Thanks.

I see no reason why not. I haven't used DrySQL, but looking at what it does, it should work with scaffolding_extensions. Try it and report back to the list.
