Working with Controllers and Models

Abstract

A single operation in Cake will generally invoke multiple MVC elements and will work in those elements simultaneously. For instance, in the previous chapter, you used the Form helper both to receive fetched data from the controller and model, and to send user form data to the controller for processing. Changing something in the controller can affect how the Form helper behaves, which is most noticeable when manipulating something like the $this->data variable.
