EXT Grid面板不会填充数据并创建空行

Question

我正在尝试使用示例数据填充网格，所有我看到的是正在创建的行而没有数据。 但是，列标题存在。 我尝试了针对类似问题提出的各种步骤，似乎没有任何工作。 这里的任何帮助都会很棒。

Ext.define('TestModel', {
extend: 'Ext.data.Model',
id_property: 'test_id',
fields: [
   {name: 'Date', type: 'string'},
   {name: 'Notifications', type: 'string'},
   {name: 'Status',  type: 'string'}
]
});

Ext.define('D.application.component.dataexplorer.ErrNotifGridPanel',{
extend: 'Ext.grid.Panel',

initComponent: function()
{
    this.currUserId = DesktopConfig.data.items[0].raw.User_Id;

    var defaultModel = [
                        {
                            header: 'Date',
                            dataIndex: 'Msg_Date',
                            sortable: true                        
                        },
                        {
                            header: 'Notifications',
                            dataIndex: 'Content',
                            sortable: false
                        },
                        {
                            header: 'Status',
                            dataIndex: 'Msg_Status',
                            sortable: true,
                            center: true
                        }];

您的列和模型字段具有不同的名称。

列dataIndex应映射到模型中的字段name。
