    Default Load list dynamically using ajax, or JsonP

    Load list dynamically using ajax, or JsonP


    Hi guys, I'm creating an app that load a list of hotels into a list from Mysql using a php file. so for that i have a model called hotel :
    Code:
    Ext.define('OdicyApp.model.Hotel', {
        extend : 'Ext.data.Model',
        config : {
            fields : [
                { name : 'Nom', type : 'string' },
                { name : 'photo', type : 'string' },
                { name : 'etoile', type : 'int' },
                { name : 'ville', type : 'string' }
            ]
        }
    });
    a Store that load the data using either ajax or JsonP (both dont work for me :S) :
    Code:
    Ext.define('OdicyApp.store.HotelsStore', {
       extend : 'Ext.data.Store',
       id : 'HotelsStore',
       config : {
           model : 'OdicyApp.model.Hotel',
           autoload: true,
           proxy : {
               type : 'ajax',
               url  : './server/test.php',
               
               reader : {
                   type : 'json',
                   rootProperty: 'hotels'
               }
           }
       }  
    });
    a view that containes the list :

    Code:
    Ext.define('OdicyApp.view.Hotels', {
        extend : 'Ext.tab.Panel',
        xtype  : 'HotelsList',
        id : 'HotelsView',
        config : {
            title : 'Liste des hotels',
            iconCls: 'user',
            items : [
                {
                    xtype : 'list',
                    itemtpl :'<img class="photo" src="{photo_url}" width="100" height="100"/>\n\
                            <h2>{name}</h2>\n\
                            <div class="info">{address} <br/> {description} <br/><img src="{etoile_url}"/></div>',
                    title : 'Odicy Recommande',
                    store : 'HotelsStore',
                    height : 300
                }
            ]
        }
    });
    and the server side file .php returns valid json :
    Code:
    <?php
        $server = "localhost";
        $user   = "root";
        $password = "";        
        $bdd = "test";
        
        mysql_connect($server, $user, $password);
        mysql_select_db($bdd);
        
        $query = "select * from etablissement";
        $result = mysql_query($query) or die('nooo');
        $return['hotels'] = '';
        while ($line = mysql_fetch_array($result)){
            $return['hotels'][] = array(
                "name" => $line['nom'],
                "photo_url" => $line['photo'],
                "ville" => $line['ville'],
                "etoile_url" => $line['etoile']
            );
        }
        echo json_encode($return);
    ?>

    Can any one tell me please what do I need to make it work .. by the way i get a warning in my console :
    Synchronously loading 'Ext.dataview.List'; consider adding 'Ext.dataview.List' explicitly as a require of the corresponding class

    Try changing rootProperty to root.

    Are you using sencha touch 2.0 framework ? if, yes then rootProperty is ok.
    may be need to change your view try this view -
    Code:
    Ext.define('OdicyApp.view.HotelList', {
        extend : 'Ext.dataview.List',
        xtype  : 'HotelsList',
        id : 'HotelsView',
        title : 'Odicy Recommande',
        store:'HotelsStore',
        height:300,
        itemtpl :'<img class="photo" src="{photo_url}" width="100" height="100"/>\n\                        <h2>{name}</h2>\n\  
                          <div class="info">{address} <br/> {description} <br/>
    <img src="{etoile_url}"/></div>',
              });
