Questions tagged [extjs-mvc]

Attempt to implement MVC-like pattern in ExtJS framework, using the terms from the pattern and some of the concepts.

The following is how ExtJS defines "MVC" in their codebase:

Model is a collection of fields and their data (e.g. a User model with username and password fields). Models know how to persist themselves through the data package, and can be linked to other models through associations. Models work a lot like the Ext JS 3 Record class, and are normally used with Stores to present data into grids and other components

View is any type of component - grids, trees and panels are all views.

Controllers are special places to put all of the code that makes your app work - whether that's rendering views, instantiating Models, or any other app logic.
