Emberjs-1.0.0 app - 未捕获TypeError：对象[object Object]没有方法'applyPartial'

Question

我在 rails-4 应用上使用最新的Emberjs-1.0.0和Ember-data 1.0.0-beta-2的canary版本。当我使用带有来自rails应用程序的emberjs应用程序中的确切代码的 jsfiddle 时，不会抛出任何错误，但是当我启动rails应用程序并尝试转到该应用程序的索引页面时ember-app，它会抛出错误未捕获TypeError：对象[object Object]没有方法'applyPartial'

没有提到任何其他内容使得调试或确定问题变得困难。我已经删除了turbo-links，所以这不是一个因素。

基于未捕获的异常抛出，它归结为emberjs中的这一行 https://github.com/emberjs/ember.js/blob/8624e8513a8db0294856cd3f559127dd7a7820b3/packages/ember-runtime/lib/system/core_object.js#L147

Class.PrototypeMixin.applyPartial(Class.prototype);

此屏幕截图基于未在rails-4应用中加载的emberjs-app

callstack的屏幕截图，这里显示超类为Store，有时显示unknownMixin

@Jeremy here是渲染后在我的页面中显示的完整标签列表。我通过查看页面源得到了这个 rake tmp：clear rake assets：clean ，但问题仍然存在

由于ember-rails中有Gemfile，您可能会获得它提供的Ember版本，而不是app/assets/javascripts/lib/development中的版本。您可以在浏览器中加载/assets/ember.js进行验证。如果您想确保获得自定义版本，请在application.js

中使用此版本

//= require lib/development/ember

或者更确切地说，您可以完全删除application.js中的余烬，并将最新的金丝雀余烬直接包含在您的布局中。

<script type='text/javascript' src="http://builds.emberjs.com/canary/ember.js"></script>

[更新]：好的，问题是你多次包含ember.js（可能还有多个版本）。当你第一次发布脚本标签的位列表时，我错过了它，但如果仔细观察，你会看到Ember和Ember Data被包含在顶部（脚本的第4和第5行），然后它们就是每个都包括两个底部的更多次。

...
<script src="/assets/ember.js?body=1"></script>
<script src="/assets/ember-data.js?body=1"></script>
...
<script src="/assets/lib/development/ember-data.js?body=1"></script>
<script src="/assets/lib/development/ember.js?body=1"></script>
<script src="/assets/lib/production/ember-data.js?body=1"></script>
<script src="/assets/lib/production/ember.js?body=1"></script>
...

我的猜测是application.js需要一次性使用

//= require ember

然后用require_tree

再次拾起它

//= require_tree .

通常，您希望将外部库（您未亲自维护的代码）存储在应用的vendor目录中。这将允许仍然使用require_tree来获取一次性包含的所有自己的javascript。在我使用ember-rails的项目中，我的结构如下所示：

app
  assets
    javascripts
      # All my own stuff goes here
vendor
  assets
    ember
      development
        ember.js
        ember-data.js
      production
        ember.js
        ember-data.js

如果您在ember-rails中使用vendor，

require ember会在application.js中找到这些版本。您需要确保在每个config.ember.variant文件中设置config/environments/*.rb。例如，在config/environments/development.rb中，您需要添加以下内容：

config.ember.variant = :development
