如何在Ember.js中對對象排序？

Question

我曾嘗試過這篇文章 ，但收效甚微。

我有一個示例Ember.js應用程序，正在嘗試對“博客文章”進行排序，其中最新文章排在第一位。 我要去哪里錯了？

index.html

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

    ...

    <!-- relevant section -->
    <section id="posts" class="col-md-12">
        {{#each post in model}}
            <div class="post row">
                <h3 class="title">{{post.title}}</h3>
                <div class="body">{{post.body}}</div>
            </div>
        {{/each}}
    </section>
</script>

router.js

Blog.Router.map(function() {
    this.resource('posts', {path: '/'});
});

Blog.PostsRoute = Ember.Route.extend({
    model: function() {
        return this.store.find('post');
    }
});

posts_controller.js

Blog.PostsController = Ember.ArrayController.extend({
    itemController: 'post',
    sortProperties: ['id'],
    sortAscending: false,
    actions: {
        createPost: function() {
            var title = this.get('newTitle');
            var body = this.get('newBody');
            if(!title.trim() || !body.trim()) { return; }

            var post = this.store.createRecord('post', {
                title: title,
                body: body
            });

            this.set('newTitle', '');
            this.set('newBody', '');

            post.save();
        }
    }
});

post.js

Blog.Post = DS.Model.extend({
    title: DS.attr('string'),
    body: DS.attr('string')
});
Blog.Post.FIXTURES = [
    {
        id: 1,
        title: 'Hell Is Other Robots',
        body: 'You know the worst thing about being a slave? They make you work, but they don\'t pay you or let you go. Kif, I have mated with a woman. Inform the men. Now, now. Perfectly symmetrical violence never solved anything.'
    },
    {
        id: 2,
        title: 'The Luck of the Fryrish',
        body: 'Tell them I hate them. There\'s no part of that sentence I didn\'t like! Fetal stemcells, aren\'t those controversial? Daylight and everything. That\'s not soon enough! You\'re going to do his laundry? Oh right. I forgot about the battle. Hey, whatcha watching?'
    },
    {
        id: 3,
        title: 'The Duh-Vinci Code',
        body: 'I\'ve been there. My folks were always on me to groom myself and wear underpants. What am I, the pope? Actually, that\'s still true. You seem malnourished. Are you suffering from intestinal parasites? And remember, don\'t do anything that affects anything, unless it turns out you were supposed to, in which case, for the love of God, don\'t not do it! Oh, I always feared he might run off like this. Why, why, why didn\'t I break his legs?'
    }

您只需要綁定到arrangedContent屬性，而不是直接綁定到模型。

{{#each post in arrangedContent}}
    <div class="post row">
        <h3 class="title">{{post.title}}</h3>
        <div class="body">{{post.body}}</div>
    </div>
{{/each}}

請參閱文檔arrangedContent 這里 。 Dom Cristie 在這里寫了一個不錯的概述 。
