Another quick announcement. We’ve released a chapter in the Documentation about object validation.

Object validation allows you to enforce business logic related to your data easily. It also allows you to persist your objects so that your application can communicate error messages back to the user or handle the errors in some other way. It’s a very clean way of handling logic that can be very repetitive if you choose to write it all out by hand instead.

Per gets down and dirty with a new chapter in the Documentation called Dirty Records. Really it’s all about tracking change to your database records dynamically.

Give it a read and learn about the power of methods like hasChanged(), XXXHasChanged(), XXXChangedFrom(), changedProperties(), allChanges(), and more.

A big part of Wheels’s included ORM is its use of associations to describe relationships between models. It’s been a long time coming, but we released a chapter in the Docs about associations along with the 0.9.1 release of ColdFusion on Wheels.

Per whipped up a quick chapter on Sending Files with Wheels’s sendFile() function.

You may feel that sending non-HTML files to the browser is a trivial task, but this functionality makes securing those files dead simple.

Thanks, Per!

Today, I released a chapter in the Documentation called Using Routes.

Routes are a pretty cool feature of Wheels because they let you step outside of the URL convention that can sometimes feel like shackles.
