问题 I'm new to Cake, and to MVC's in general. I want to establish good habits from the get go. Among the good habits are keeping controllers lean, and making the models fat. But it's a bit of a moving target for a noob like me. If I need to pass info from one model to another, do I just dump all that into the controller? Try to make it work in a model?

问题 I'm trying to build a simple Java Swing application using the MVC architecture pattern. What I've done is create the user interface components (as private) in my views, and have public methods that return the components. These methods are then called by the controllers, through which I can write methods for event/action listeners.
