I agree that's a catch-22. But the broken part is not migrations, but rather scaffolding. So let's think about how we can fix scaffolding in a way that it doesn't require the database to exist before running. Even before this, I've been burned by scaffolding requiring the database to be in place before it would run. The only reason this haven't been fixed yet is probably that most of core doesn't do script/generate scaffold all that much. The auto-migration feature is really nice in a non-scaffolding workflow, though. The way I use and work with a Rails application is by creating one model at the time as they're needed to make the application work. So with a shop, I'd start by creating the product model, making it work, and then moving on to the cart or the order, and every step of the way making it all work. This is in contrast to, say, creating the entire schema first, then starting to work on the model or the controller. And that's why the current scaffolding approach is broken. It assumes that I create my database first while the new model of migrations encourage a concurrent approach. >But, no, that doesn't work either, as the scaffold generator > blows up if the table isn't there. Yup, current scaffolding generator is broken. > (On a tangential note, if the model and scaffold generators _do_ have > to create migrations, they should really be called > 'create_tablename', not 'add_tablename', just to be consistent.)
