Question

我是Ember JS的新手，这是一个小而简单的应用程序，用户在主视图中创建一个规则集，每个规则集都附加在主视图中，每个视图都包含一个用户的小视图可以注册规则，然后在规则集视图中列出每个规则，这样可以正常工作但是当用户创建规则集时，第一个规则集内的规则会在新规则集视图中重复。

我在做什么？

注意：我不想使用路线。

自己尝试一下，这样你就可以看到我在说什么。

我会提供任何帮助

Answer 1

如果我理解正确，我认为它可能就在哪里

<p>Rules created:</p>
{{#each pat in controller}}
  {{view Parsertool.PatternruleView controller=pat}}
{{/each}}

你不想在controller.ruleset中观看#each pat吗？否则它只会通过所有控制器。

另一个控制器内的Ember js控制器正在重复数据
