    Default Displaying Twitter Search Query

    Displaying Twitter Search Query


    Hi there,

    I've been following a youtube tutorial on creating a Sencha App in Sencha Architect to simply display tweets. I'm now trying to modify it to show tweets containing a keyword.

    My JSON link is valid. But I cannot get the app to display the tweet data. I think it's a simple problem. But here is the code.

    JSON link: http://search.twitter.com/search.json?q=ojai&count=3

    Code:

    Model:
    Code:
    Ext.define('MyApp.model.Tweet', {    extend: 'Ext.data.Model',
    
    
        config: {
            fields: [
                {
                    name: 'text',
                    mapping: 'results.text'
                },
                {
                    name: 'created_at',
                    mapping: 'results.created_at',
                    type: 'date'
                },
                {
                    name: 'profile_image_url',
                    mapping: 'results.profile_image_url'
                },
                {
                    name: 'name',
                    mapping: 'results.from_user_name'
                }
            ]
        }
    });
    Store:
    Code:
    Ext.define('MyApp.store.Tweets', {    extend: 'Ext.data.Store',
    
    
        requires: [
            'MyApp.model.Tweet'
        ],
    
    
        config: {
            autoLoad: true,
            model: 'MyApp.model.Tweet',
            storeId: 'Tweets',
            proxy: {
                type: 'jsonp',
                url: 'http://search.twitter.com/search.json?q=ojai&count=20',
                reader: {
                    type: 'json'
                }
            }
        }
    });
    Views:
    Code:
    Ext.define('MyApp.view.MyPanel', {    extend: 'Ext.Panel',
    
    
        config: {
            layout: {
                type: 'card'
            },
            items: [
                {
                    xtype: 'toolbar',
                    docked: 'top',
                    title: 'Ojai Tweets',
                    items: [
                        {
                            xtype: 'button',
                            hidden: true,
                            itemId: 'Back',
                            ui: 'back',
                            text: 'Back'
                        }
                    ]
                },
                {
                    xtype: 'list',
                    id: 'TweetList',
                    itemId: 'mylist',
                    itemTpl: [

                    ],
                    store: 'Tweets'
                },
                {
                    xtype: 'panel',
                    id: 'TweetPreview',
                    padding: '12px',

    Default Solved!

    Solved!


    woooo! Solved! I forgot to set the root property to "results" in the jsonreader

    Code:
                reader: {                type: 'json',
                    rootProperty: 'results'
                }
