FormObject, View, ViewModel • Presenter - Jay Fields (http:/ /blog.jayfields.com/2007 /03/ rails-presenter-pattern.html) „The Presenter pattern addresses bloated controllers and views containing logic in concert by creating a class representation of the state of the view. An architecture that uses the Presenter pattern provides view specific data as attributes of an instance of the Presenter. The Presenter's state is an aggregation of model and user entered data.”
