Sencha touch Sencha touch Json数据仅显示2条记录

我刚刚用Sencha触摸列表和Json阅读器创建了一个小应用程序。有30多条记录，但仅显示2条数据记录

代码如下：

    Ext.regModel('Story', {
        idProperty: 'story_id',
        fields: [
            {name: "story_id",          type: "int"},
            {name: "id",                type: "int"},
            {name: "category_id",       type: "int"},
            {name: "story_content",     type: "string"},
            {name: "image",          type: "string"},
            {name: "story_posted_on",   type: "date"},
        {name: "story_modified_on", type: "date"},
            {name: "active_status",     type: "int"}
        ]
    });

    Ext.regStore('StoryStore', { 
        model: 'Story',
        sorters: [{
            property: 'story_posted_on',
            direction: 'DESC' 
        }],
        autoLoad: true,
        proxy: {
            type: 'ajax', 
            url: '../backend/index.php?r=stories/getStories',
        },
        reader: {
            type: 'json',
        }
    });


    App.views.FMJList = new Ext.List({
        id: 'FMJList',
        store: 'StoryStore',
        itemTpl: '<div class="story">'+
            '<div class="story_content">'+
                '<tpl if="image">'+
                    '<div class="story_img" style="background-image: url(http://localhost/app/uploads/stories/{image});"></div>'+
                '</tpl>'+
                '<div class="story_content">{story_content}</div>'+
                '<div class="story_display_name">{id}</div>'+
            '</div>'+
        '</div>'
    });

发现问题其实是idProperty:“story_id”。默认情况下，idProperty设置为id并且它是唯一的，我认为idProperty不会覆盖默认值。有人知道修复方法吗？

您能添加JSON响应吗？显示了哪些记录？显示了哪两个故事？我注意到的一点是，您将一些值读取为“int”，但将它们作为字符串发送（例如，story_id）。它返回最后一个值，并在第一个值之后返回第二个值。所以201和199。尝试在chrome控制台中输入Ext.getStore（'StoryStore'）.getCount（），查看存储中有多少条记录。这将有助于将问题缩小到存储区或列表。可能与您的问题无关，但不应该引用JSON键吗？
