javascript - 如何从父数组视图显示子对象视图

Question

我有以下显示产品列表的内容。当我单击产品时，我只想查看产品信息。

我设法让产品信息出现的唯一方法是在父产品模板上使用{{outlet}}or {{render}}，这不是我想要的。

var App = Ember.Application.create();

App.ApplicationController = Ember.Controller.extend({

});

App.ProductsController = Ember.ArrayController.extend({
    sortProperties: ['id']
});

App.Router.map(function () {
    this.resource('products', function () {
        this.resource('product', { path: ':product_id' });
    });
});

App.ProductsRoute = Ember.Route.extend({
    model: function () {
        return App.Products.find();
    }
});

// Models
App.Store = DS.Store.extend({
    revision: 11,
    adapter: 'DS.FixtureAdapter'
});

App.Products = DS.Model.extend({
    title: DS.attr('string'),
    artist: DS.attr('string'),
    image: DS.attr('string'),
    price: DS.attr('number'),
    url: DS.attr('string')
});



App.Products.FIXTURES = [
    {
        id: 1,
        title: 'The Door',
        artist: 'Religious Knives',
        image: 'http://ecx.images-amazon.com/images/I/51og8BkN8jL._SS250_.jpg',
        large_image: 'http://ecx.images-amazon.com/images/I/51og8BkN8jL._SS500_.jpg',
        price: 9.98,
        url: 'http://www.amazon.com/Door-Religious-Knives/dp/B001FGW0UQ/?tag=quirkey-20'
    },
    //etc etc
];

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

                                {{/linkTo}}
                            </div>
                            <div class="item-artist">{{product.artist}}</div>

                        <div class="item-info">

                                    <label>Quantity:</label>

                                </p>
                                <p>
                                    <button data-bind="click: $parent.addItem">Add to Cart</button>
                                </p>

                            </div>
                            <div class="item-link"><a {{bindAttr href="url"}}">Buy this item on Amazon</a></div>
                            <div class="back-link"><a href="#/">&laquo; Back to Items</a></div>
                        </div>
                    </div>

            </script>

问题是当从产品返回产品时，产品不再列出

App.ProductsRoute = Ember.Route.extend({
    model: function () {
        return App.Products.find();
    }
});


App.ProductRoute = Ember.Route.extend({
    model: function (params) {
        return App.Products.find(params.product_id);
    },
    renderTemplate: function () {
        this.render('product', {   // the template to render
            into: 'application',                // the template to render into
            outlet: 'main',       // the name of the outlet in that template
        });
    }
});

您可以将路由器映射更改为以下内容：

App.Router.map(function () {
    this.route('products');
    this.route('product', { path: 'product/:product_id' });
});

还可以考虑使用索引路由，在页面加载时将您转移到特定位置：

App.IndexRoute = Em.Route.extend({
    redirect: function() {
        this.transitionTo('products');
    }
});
