URL Validator defaultScheme

I’m sure this is straightforward, but I can’t figure it out. I’m trying to set a defaultScheme to the Yii URL validator in my model, so that it accepts addresses like www.something.com as well as http://www.something.com.

To do this, I’m using the following code in my model rules():


array('website', 'url', 'defaultScheme' => 'http://'),


This doesn’t seem to be working, and I still get an “Website is not a valid URL” error when trying to update. What am I doing wrong?

array('website', 'url', 'defaultScheme' => 'http'),
