MVP, JavaFx and components references
java,design-patterns,model-view-controller,javafx
JavaFX has been designed to work with the MVC pattern. Hence it is much easier to use MVC than MVP. In MVP Presenter is responsible for formatting the data to be displayed. In JavaFX, it is done automatically by View. Here's a quick overview of JavaFX MVC: Model - the...
Controller and model/service separation of logic

It is fine to pass a model into a view, a good way to do it is like this: public function show($id) { $thing = Thing::findOrFail($id); return view('showAThing')->with('thing', $thing); } Using findOrFail() in this context will throw a 404 error if the item doesn't exist in your database. This is...
