    Default Unanswered: MVC architecture of extjs

    Unanswered: MVC architecture of extjs


    In my below code, I am trying to connect my main js file(app.js) with the controller and view. Any how I successed in connecting to controller part (showing console messages of controller). Now I am trying to connect to view part with controller, as you can see below. I am failed to do so. What possible mistake could I have been doing here, I can't understand. Here I am trying to understand the function of MVC architecture of extjs. It is my first attempt to understand. Please help

    app.js (main js file)
    Code:
    Ext.application({
        name: 'Game',
        appFolder: 'app',
        controllers: ['Sudoku'],
        //views: ['Sudoku'],
        launch: function () {
            console.log("app.js");
        }
    });
    controller ('app' folder --> 'controller' folder)

    Code:
    Ext.define('Game.controller.Sudoku', {
        extend: 'Ext.app.Controller',
        views: ['Sudoku'],
        init: function () {
            console.log("controller init");
        },
        onLaunch: function () {
            console.log("controller onLaunch");
        }
        
    });
    view ('app' folder --> 'view' folder)

    Code:
    Ext.define('Game.view.Sudoku', {
        initComponent: function () {
            //my complete sudoku js file here
            console.log("view");
            this.callParent();
        },
        
    });
    If the connecting of 'model' part differs then please explain that also to me..

    2 problems:

    1) You never call the superclass initComponent method:

    Code:
    this.callParent();
    2) You never initialize the view anywhere. The views config just says these are the views we need available. You need to create an instance of it:

    Code:
    new Game.view.Sudoku();

    @evant I did call

    this.callParent(); //I am not sure whether it is correct

    I am not sure where to call new Game.view.Sudoku();

    and I have called the initComponent for 'view'.

    Can you please just show me in my sample code where to add these steps?

    I wasted a lot of time on this
