has_many :customers
Of course, if you have more complex relationships you can still write them. I imagine that this would be handy for Railifying a legacy database with lots of tables.

These magic models should be a part of vanilla rails IMHO; it's definitely that good an idea! - lukeredpath, on 10/12/2007, -0/+0Pretty nifty; a cool piece of hackery (I mean that in a good way); but ultimately pointless IMO.
Yes, its good to keep things DRY and keep your constraints and associations in one place and in the name of expressive, declrative programming I’d much rather keep them in the model where they belong and use my database as a dumb data store.
Why would I want to view the schema every time I want to know about my model’s constraints and associations?
Finally, as cool as the models without classes trick is, what use is it really? You’re still gonna need the model file unless you’re happy with an anaemic domain model. - nicwilliams, on 10/12/2007, -1/+0As long as I'm using the right fad for the job :)
