javascript – Emberjs动态段：加载路由时出错：TypeError {}

我想在这里熟悉动态片段.这是我想要实现的：

当我访问“/#/库存”时,它将在“库存”模板中列出库存模型.这是成功的.

当我点击个别库存ID时,它将访问/#/ inventory / 1为1是库存ID,它将启动“库存”模板.这也是成功的.

但是,当我尝试从地址栏直接访问/#/ inventory / 1时,当我按F5时,出现这个错误 – 加载路由时出错：TypeError {}

完整的错误列表：

这是我的app.js：

Gymi = Ember.Application.create();

// Route map
Gymi.Router.map(function() {
    this.resource('inventories',{ path: '/inventories' },function() {
        this.resource('inventory',{ path: '/:inventory_id' });
    });
    this.resource('products');
});

// inventory models
Gymi.Inventory = Ember.object.extend();
Gymi.Inventory.reopenClass({
    items: [],all: function() {
        this.items = [{
            id: 1,name: 'item1',cost: '20.00',qty: 10
        },{
            id: 2,name: 'item2',{
            id: 3,name: 'item3',{
            id: 4,name: 'item4',qty: 10
        }];

        return this.items;
    }
})

// inventory controller
Gymi.InventoriesController = Ember.Controller.extend({
    inventories: Gymi.Inventory.all()
});

以下是模板：

<script type="text/x-handlebars">
<h2>{{titlE}}</h2>

<ul>
    <li>{{#linkTo 'inventories'}}Inventories{{/linkTo}}</li>
</ul>

{{outlet}}
</script>

<script type="text/x-handlebars" data-template-name="inventories">
<h2>Inventory</h2>

<table class="table">
<tbody>
{{#each inventory in inventories}}
    {{#with inventory}}
    <tr>
    <td>{{#linkTo 'inventory' inventory}}{{iD}}{{/linkTo}}</td>
    <td>{{name}}</td>
    <td>{{Cost}}</td>
    <td>{{qty}}</td>
    </tr>
    {{/with}}
{{/each}}
</tbody>
</table>

{{outlet}}
</script>

<script type="text/x-handlebars" data-template-name="inventory">
