If I make a change to a database table, how do I recreate the model to  
reflect the change?

As far as I know you have to do it manually. There are still some  
tedious things you have to do. I’ve been working on that pretty much  
all night.

Wow, that is slick. I just tried it out.

I’m realizing quickly why this framework is getting so much attention.

Oh, I misread. Just a table. I was referring to a the model as a  
whole. Joey’s right… you don’t.

Once you set your app for production mode, the model is only  
created/modified when you start your app, so as far as I know you have  
to stop your webserver and restart it.
