    Question Answered: MVC error with automatic function generation

    Answered: MVC error with automatic function generation


    So I'm following along with the MVC part-1 senchacon video (http://www.sencha.com/conference/ses...-in-depth-pt-1) and I've run into an issue...

    I've gotten to the part where I now have several views, and a main controller and now I am attempting to add the functionality to submit the contact form. If it helps I've completed everything up to 28:23 in the video.

    In the video Ed mentions that once you specify a reference to the contact form, a new function is automatically created called this.getContactForm(). When I follow the demo and set the result of that function to a variable and console.log it, as he does in the video - I should get an output of the object.

    Except, I'm getting this result instead.
    Uncaught TypeError: Object [object Object] has no method 'getContactForm'

    Any suggestions on proceeding would be appreciated.

  2. Ok, so I did some digging around and it appears as though some of the configuration has been changed since this video was recorded...

    Here is the main.js in the video...

    Code:
    Ext.define('Sencha.controller.Main', {
        extend: 'Ext.app.Controller',
    
        views: ['Home', 'Products', 'Blog', 'Contact'],
    
        refs: [
            {
                ref: 'contactForm',
                selector: '#contactForm'
            }
        ],
    
        init: function() {
            this.control({
                'button[action=submitContact]': {
                    tap: 'submitContactForm'
                }
            });
        },
    
        submitContactForm: function() {
            var form = this.getContactForm();
    
            console.log(form);
        }
    });
    
    
    Here is what I found in the docs that does work...

    Code:
    Ext.define('Sencha.controller.Main', {
        extend: 'Ext.app.Controller',
    
        views: ['Home', 'Products', 'Blog', 'Contact'],
    
        config: {
            refs: {
                    contactForm: '#contactForm'
                }
        },    
    
        init: function() {
            this.control({
                'button[action=submitContact]': {
                    tap: 'submitContactForm'
                }
            });
        },
    
        submitContactForm: function() {
            var form = this.getContactForm();
    
            console.log(form);
        }
    });
    Note that refs is now inside the config and the actual name of the ref corresponds to the function name that is auto generated.
