    Default Unanswered: Populate a Form, using MVC pattern

    Unanswered: Populate a Form, using MVC pattern


    Hi Guys,
    I'm a new EXTJS user.

    I try to populate my Form, but i dont get it.
    I use a Store who return a json string and with this string i try to populate the form.

    Store:
    Code:
    Ext.define('FM.store.current_message_details', {
        extend: 'Ext.data.Store',
        model: 'FM.model.current_message_detail',
        autoLoad: true,
        proxy: {
            type: 'ajax',
            url: 'data/current_message_details.php',
            reader: {
                type: 'json'
    
            }
        }
    
    });
    view:
    Code:
    Ext.define('FM.view.message.current_message_details', {
        extend: 'Ext.form.Panel',
        alias: 'widget.current_message_details',
        store: 'current_message_details',
        title: 'Detallierte Ansicht',
        id:'YourFormID',
        layout: 'column',
        border:       true,            //Soll ein rand vorhanden sein?
        frame:        true,            //Soll ein Rahmen vorhanden sein?
        labelWidth:   80,            //Breite der Beschriftung für textfelder
        margin: '0 0 0 355',
        initComponent: function () {
    
            this.items= [
    
                { xtype: 'textfield', fieldLabel: 'Job_nummer',   dataIndex: 'job_nummer',        margin:'0 0 0 1'},
                { xtype: 'textfield', fieldLabel: 'Fluggeber',          dataIndex: 'fluggeber',         margin:'0 0 0 1'},
                { xtype: 'textfield', fieldLabel: 'Kommentar',   dataIndex: 'kommentar',         margin:'0 0 0 1'},
                { xtype: 'textfield', fieldLabel: 'Typ',                dataIndex: 'typ',               margin:'0 0 0 1'},
                { xtype: 'textfield', fieldLabel: 'Format',             dataIndex: 'format',            margin:'0 0 0 1'},
                { xtype: 'textfield', fieldLabel: 'Parameter',          dataIndex: 'parameter',         margin:'0 0 0 1'},
                { xtype: 'textfield', fieldLabel: 'Export_date_start',dataIndex: 'export_date_start', margin:'0 0 0 1'},
                { xtype: 'textfield', fieldLabel: 'Export_date_end',dataIndex: 'export_date_end',  margin:'0 0 1'},
                { xtype: 'textfield', fieldLabel: 'pid',                dataIndex: 'pid',               margin:'0 0 0 1'},
                { xtype: 'textfield', fieldLabel: 'Minute',             dataIndex: 'minute',            margin:'0 0 0 1'},
                { xtype: 'textfield', fieldLabel: 'Stunde',             dataIndex: 'stunde',            margin:'0 0 0 1'},
                { xtype: 'textfield', fieldLabel: 'Tag',                dataIndex: 'tag',               margin:'0 0 0 1'},
                { xtype: 'textfield', fieldLabel: 'Monat',              dataIndex: 'monat',             margin:'0 0 0 1'},
                { xtype: 'textfield', fieldLabel: 'Wochentag',          dataIndex: 'wochentag',      margin:'0 0 0 1'},
                { xtype: 'textfield', fieldLabel: 'next_run',           dataIndex: 'next_run',          margin:'0 0 0 1'}
            ];
            this.callParent(arguments);
        }
    });
    controller:

    Code:
    Ext.define('FM.controller.messages', {
        extend: 'Ext.app.Controller',
        stores: ['current_listeners','current_message_details','messages'],
        models: ['current_listener','current_message_detail','message'],
        views: [
            'message.list_messages',
            'message.current_message_details',
            'listener.current_listeners'
    
    
        ],
    
        init: function() {
            this.control({
                'list_message': {
                    itemdblclick: this.current_listeners
    
                }
            });
        },
        current_listeners: function(grid, records) {
            var myStore=Ext.data.StoreManager.get('current_listeners');
            myStore.load({
                params:{
                    job_id: records.get('job_nummer')
    
                }
    
            });
            var current_message_details=Ext.data.StoreManager.get('current_message_details');
            var test= current_message_details.load({
                url: 'data/current_message_details.php',
                params:{
                    job_id: records.get('job_nummer')
                }
            });
        }
    });

    json string
    [{"id":1,"job_nummer":"14","fluggeber":"abc","kommentar":"Meldung abc","typ":"konti","format":"csv","parameter":"{\"data\":{\"total\":true}}","export_date_start":"NOW","export_date_end":"NOW + 365DAYS","pid":"0","minute":"0","stunde":"7,16","tag":"*","monat":"*","wochentag":"*","next_run":"2013-07-02 07:00:00"}]


    So now is my Question how can i populate the form with my controller ? I try to populate the form with current_message_details.load... but it doesnt work.
    I would rejoice over any help.

    greeting

    Nopkev

    See the docs for Ext.form.action.Load. Your JSON response for a form load should look something like this:

    Code:
    {
        success: true,
        data: {
            clientName: "Fred. Olsen Lines",
            portOfLoading: "FXT",
            portOfDischarge: "OSL"
        }
    }

    But i get my Data from a db. How can i creat this standard? If i use the Json string for a Grid it work, but not if i use it for the form.
    Code:
    {     success: true,     
    data: {         clientName: "Fred. Olsen Lines",         portOfLoading: "FXT",         portOfDischarge: "OSL"     } }
    PHP Code:

    if(isset($_GET['job_id'])){
      
    $runlist $pdo->prepare("SELECT * FROM job WHERE job_id=:job_id order by job_id ");
      
    $runlist->bindValue('job_id',$_GET['job_id']);
      
    $runlist->execute();
    }else{
      
    $runlist $pdo->query("SELECT * FROM job order by job_id ");
    }

    $count $runlist->rowCount();
    $i 1;
    if (
    $count >= 1) {
      while (
    $row $runlist->fetch(PDO::FETCH_ASSOC)) {
        
    $a[] = array("id" => $i'job_nummer' => $row['job_id'], 'abc' => $row['abc'], 'kommentar' => $row['kommentar'], 'typ' => $row['typ'], 'format' => $row['format'], 'parameter' => $row['parameter'], 'export_date_start' => $row['export_date_start'], 'export_date_end' => $row['export_date_end'], 'pid' => $row['pid'], 'minute' => $row['minute'], 'stunde' => $row['stunde'], 'tag' => $row['tag'], 'monat' => $row['monat'], 'wochentag' => $row['wochentag'], 'next_run' => $row['next_run']);
        
    $i++;
      }
    } else {
      
    $a "";
    }
    echo 
    json_encode($a);

    To load a form, you must format the data returned by your PHP code to conform to the structure I mentioned earlier. I usually have two server-side methods, where one returns a JSON list of data suitable for a Grid, and another which looks up/returns a single record formatted properly to load a form.

    It's entirely up to you to properly format the JSON data structure required for a form load.

    Hi,

    first thanks friend that you try to help me .

    Is this a single record formatted JSON-String or not ?

    Code:
    {"success":true,"data":{"job_nummer":"3","fluggeber":"abc","kommentar":"abc","typ":"abc","format":"abc","parameter":"abc","export_date_start":"abc","export_date_end":"abc","pid":"0","minute":"0","stunde":"7","tag":"*","monat":"*","wochentag":"*","next_run":"abc"}}
