初めての Ember アプリを作成していますが、データに少し問題があります。私のオプションは次のようです:
- Ember Data経由(これは生産の準備ができておらず、壊れている可能性があるようです)
- Ember.Object 経由 (これらの反復処理に問題があります)
- プレーンなJS配列を介して(これは単純すぎると思います)
私は行く方法は Ember.Object インスタンスを使うことだと思います:
// Attempt to modify the Blog Tutorial (http://emberjs.com/guides/) to use Ember.Object for data
App.Posts = Ember.Object.extend([
{
id: '1',
title: "Rails is Omakase",
author: { name: "d2h" },
date: new Date('12-27-2012'),
body: "I want this for my ORM, I want that for my template language, and let's finish it off with this routing library. Of course, you're going to have to know what you want, and you'll rarely have your horizon expanded if you always order the same thing, but there it is. It's a very popular way of consuming software.\n\nRails is not that. Rails is omakase."
}, {
id: '2',
title: "The Parley Letter",
author: { name: "d2h" },
date: new Date('12-24-2012'),
body: "A long list of topics were raised and I took a time to ramble at large about all of them at once. Apologies for not taking the time to be more succinct, but at least each topic has a header so you can skip stuff you don't care about.\n\n### Maintainability\n\nIt's simply not true to say that I don't care about maintainability. I still work on the oldest Rails app in the world."
}
]);
posts = App.Posts.create();
しかし、このデータをループするのに問題があります:
<!-- === POSTS === -->
<script type="text/x-handlebars" id="posts">
<table class='table'>
<thead>
<tr><th>Recent Posts</th></tr>
</thead>
{{#each model}}
<tr><td>
{{#link-to 'post' this}}{{title}} <small class='muted'>by {{author.name}}</small>{{/link-to}}
</td></tr>
{{/each}}
</table>
{{outlet}}
</script>
私のインスペクターコンソールは次のように表示されます:

では、Ember.Object インスタンス内のデータをどのようにループするのでしょうか?
