基本的灰烬模板不能在Rails中渲染

请原谅我，因为我是Ember（以及整个Javascript世界）的新手。我与ember-rails宝石创建一个Rails应用程序，我们把它叫做 '疣猪'基本的灰烬模板不能在Rails中渲染

我application.js文件如下：

//= require jquery 
//= require jquery_ujs 
//= require handlebars 
//= require ember 
//= require ember-data 
//= require_self 
//= require warthog 
Warthog = Ember.Application.create(); 
//= require bootstrap

接下来是application.html.haml文件

%html 
    %head 
    %title Warthog 
    = stylesheet_link_tag "application", :media => "all" 
    = javascript_include_tag "application" 
    = javascript_include_tag 'templates/application'

对于一些测试输出，我有一个字符串在我的application.handlebars文件中

This is a test

问题是javascripts/templates/application.handlebars未呈现。

这里是网页的源请求完成后：

<html> 
    <head> 
    <title>Warthog</title> 
    <link href="/assets/application.css?body=1" media="all" rel="stylesheet" type="text/css" /> 
    <script src="/assets/jquery.js?body=1" type="text/javascript"></script>

    <meta content="afE+P0e6I/KDeVpg/kLi8RvsPAAyYOwD6rE=" name="csrf-token" /> 
    </head> 
    <body> 
    <div id='container'> 

    </div> 
</body> 
</html>

如果将它命名为'application.js.handlebars'，会发生什么？ – josh

同样的问题，仍然不会渲染 – Anconia

将'application.html.haml'文件更改为不包含'templates/application'文件，因为它已经包含在'application.js'文件中。另外，如果你不一定需要'ApplicationController'或'ApplicationRoute'，你可以安全地不定义它们，而Ember将处理它。 – josh

确保您的应用程序车把模板被注入这种格式

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

</script>

或

<script type="text/x-handlebars" > 

</script>

命名为灰烬超级重要的，如果你的模板注入不同的名称，如：

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

</script>

然后你想要d表示使用与默认模板名称不同的模板名称的应用程序视图。

Warthog.ApplicationView = Ember.View.extend({ 
    templateName: 'templates/application' 
})

application.handlebars模板是否不会在每个请求中自动呈现？ – Anconia

我也在使用ember-rails gem，并不认为有必要包含脚本标签 – Anconia

什么是呈现的客户端？ – Kingpin2k
