javascript - 实现 ember js 后网站无法呈现

Question

背景

我正在尝试使用 ember.js 及其依赖项构建博客。基本上，我在左侧“导航栏”，内容显示在右侧。像这样的东西:

左边不动，右边不动；此外，左侧还有指向各个页面的链接。

问题

我正在使用 ember.js 来实现帖子的链接，并将帖子呈现到博客内容端。目前，我的实现没有渲染任何东西。下面是代码:

App = Ember.Application.create({});

var posts = [{
    id: '0',
    title: 'Title and title',
	  author: {name: 'Author'},
	  date: new Date('15-11-2014'),
	  content: 'Work and work.'
	},{
	  id: '1',
	  title: "Rails is Omakase",
	  author: { name: "d2h" },
	  date: new Date('12-27-2012'),
	  excerpt: "There are lots of à la carte software environments in this world. Places where in order to eat, you must first carefully look over the menu of options to order exactly what you want.",
	  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'),
	  excerpt: "My [appearance on the Ruby Rogues podcast](http://rubyrogues.com/056-rr-david-heinemeier-hansson/) recently came up for discussion again on the private Parley mailing list.",
	  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."  
}];

/*
  This will load the lists for the template to take
*/
App.ApplicationRoute = Ember.Route.extend({
  model: function(){
    return posts;
  }
});

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

App.PostRoute = Ember.Route.extend({
  model: function(params){
    return posts[params.post_id];
  }
});

/*Some small variables that*/
App.name = "Blog name";
App.tag = "TAG";
App.stub = "Stub";

我的尝试

我尝试制作两个不同的 Handlebars 脚本，一个是对帖子的引用，即

<script type="text/x-handlebars" id="posts">
          <section>
            <h3> Welcome to my blog </h3>
                <p>
                    {{outlet}}
                </p>
          </section>
         </script> 

但这没有用。我还尝试在整个 div 周围制作一个 Handlebars 脚本，但这也没有用。

如果有人能指出问题所在的正确方向:我将永远欠你的债。谢谢! :)

更新我已经更新了 HTML/js 的代码。可以查看here

Answer 1

你错过了一些关于 ember 的想法 -
命名很重要。您有帖子 - 应该在模型中，然后使用夹具适配器来声明它们。您有一个帖子模板，但没有定义或在您的路由器中的帖子路由。

this.resource("posts", {path: "/posts"}, function(){
    this.resource("post", {path: "/:post_id"});
});

您的路由器中没有索引路由。

this.resource("index", {path: "/"}, function() {});

从外观上看，您根本没有 Controller 。(尽管现在看起来您不需要它们)

如果您使用的是 ember，我建议您使用 ember-cli。它将帮助您设置应用程序结构并帮助命名约定。 http://www.ember-cli.com/

学习 ember 教程也没有什么坏处——无论是在 ember 站点本身还是在其他站点上的教程。尝试做一个尽可能最新的代码，因为代码移动得如此之快以至于教程很快就会过时。

链接

{{#each post in model}}
    <li> {{#link-to "post" post}} {{post.title}} {{/link-to}}</li>
{{/each}}

所以对于链接 - {{#link-to "template"model}} 其中 template 是模板，model 是你通过链接传递的元素。因此，在您的情况下，它是“发布”模板，并且由于您将模型定义为发布在您使用的每个语句中。通过文档 http://emberjs.com/guides/templates/links/#toc_the-code-link-to-code-helper
