javascript - Emberjs 动态段 : Error while loading route: TypeError {}

Question

我想在这里熟悉一下动态分割。这是我想要实现的目标:

当我访问“/#/inventories”时，它将在“inventories”模板中列出库存模型。这是成功完成的。

当我点击单个库存 ID 时，它会访问/#/inventories/1，因为 1 是库存 ID，它会启动“库存”模板。这也成功地完成了。

但是，当我尝试直接从地址栏访问/#/inventories/1 时，当我按 F5 时，会出现此错误 - Error while loading route: TypeError {}

完整的错误列表:

} has no method 'find' 

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',
            cost: '20.00',
            qty: 10
        }, {
            id: 3,
            name: 'item3',
            cost: '20.00',
            qty: 10
        }, {
            id: 4,
            name: 'item4',
            cost: '20.00',
            qty: 10
        }];

        return this.items;
    }
})

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

模板如下:

<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">
<h4>Inventory</h4>

<ul>
    <li>{{id}}</li>
    <li>{{name}}</li>
    <li>{{cost}}</li>
    <li>{{qty}}</li>
</ul>
</script>

不是对 OP 的回答，而是对所有在 2013 年 9 月 1 日之后收到错误的人的回答，这可能是由于将 Ember Data 更新到最新的 1.0 版本。所以你必须使用

this.store.find('model');

代替

App.Model.find();
