ここで動的セグメントに慣れようとしています。これが私が達成したいことです：
「/#/inventories」にアクセスすると、「inventories」テンプレートに在庫モデルが一覧表示されます。これは正常に行われます。
個々の在庫 ID をクリックすると、/#/inventories/1 にアクセスし、1 が在庫 ID になり、「在庫」テンプレートが起動します。これもうまくいきます。
ただし、アドレスバーから直接/#/inventories/1にアクセスしようとすると、F5を押すと、このエラーが発生します-Error while loading route: TypeError {}

これが私のものapp.jsです：
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()
});
テンプレートは次のとおりです。
<script type="text/x-handlebars">
