我正在尝试遵循这个基本的 Ember.js 教程,但对“帖子”模型没有运气。我根据演示设置了所有内容,但是出现错误:

Uncaught More context objects were passed than there are dynamic segments for the route: post

由于这是我第一次使用 Ember.js 应用程序,老实说,我不知道这意味着什么。任何帮助(实际上是任何东西)将不胜感激。

这是我的 App.js

App = Ember.Application.create();

App.Store = DS.Store.extend({
    adapter: 'DS.FixtureAdapter'
});

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

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

App.Post = DS.Model.extend({
    title: DS.attr('string'),
    author: DS.attr('string'),
    intro: DS.attr('string'),
    extended: DS.attr('string'),
    publishedAt: DS.attr('date')
});

App.Post.FIXTURES = [{
        id: 1,
        title: "Rails in Omakase",
        author: "d2h",
        publishedAt: new Date('12-27-2012'),
        intro: "Blah blah blah blah",
        extended: "I have no clue what extended means"
    }, {
        id: 2,
        title: "Second post",
        author: "second author",
        publishedAt: new Date('1-27-2012'),
        intro: "second intro",
        extended: "Second extended"
    }];

这是帖子的html。

<script type="text/x-handlebars" id="posts">
    <div class="container-fluid">
        <div class="row-fluid">
            <div class="span3">
                <table class='table'>
                <thead>
                    <tr><th>Recent Posts</th></tr>
                </thead>
                {{#each model}}
                <tr><td>
                    {{#linkTo 'post' this}}{{title}} <small class='muted'>by {{author}}</small>{{/linkTo}}
                </td></tr>
                {{/each}}
                </table>
            </div>
            <div class="span9">
                {{outlet}}
            </div>
        </div>
    </div>
</script>
<script type="text/x-handlebars" id="post">
    <h1>{{title}}</h1>
    <h2> by {{author}} <small class="muted">{{publishedAt}}</small></h2>

    <hr>

    <div class="intro">
        {{intro}}
    </div>

    <div class="below-the-fold">
        {{extended}}
    </div>
</script>

我认为您的意思是指定路线。

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

该错误听起来像是您正在传递类似的东西post/12并且您没有指定动态段(写为:post_id) 这:是指定动态段的重点。

取自Ember.js 文档

接受的答案有效。

但是,考虑到示例中操作的位置,更正确的解决方法是不理会以下内容:

this.resource('posts');

并在其下方添加:

this.resource('post', { path: '/post/:post_id'});
