yep. Views are for laying out stuff. controllers for pasing data to view and models for obtaining data. If your model passes the data to the controller so that the controller has to process the data as little as possible for the view http://gluei.com/blog/view/cakephp-best-practices-fat-models-and-skinny-controllers http://cakebaker.42dh.com/2008/01/19/fat-models-and-how-they-change-how-you-use-the-model-class/ There are some performance drawbacks with using requestaction like that.
