将字符串标记为HTML安全 [英] Marking a string as HTML safe

问题描述

我正在尝试构建我的第一个Rails应用程序，并且正在使用 Ryan Heath的navigation_helper 插件提供导航中的当前课程.我建立了我的命名路由，如下所示:

I am trying to build my first Rails application and I'm using Ryan Heath's navigation_helper plugin to give me the current class in my navigation. I built my named routes as follows:

match 'games' => 'games#index', :as => :games
match 'new' => 'games#new', :as => :new
match 'previous' => 'games#previous', :as => :previous
match 'settings' => 'settings#index', :as => :settings

然后在我的application_layout中添加以下代码

Then in my application_layout I added the following code

<%= navigation([:games, :new, :previous, :settings]).html_safe %>

根据我对Rails的了解，html_safe应该强制HTML正确呈现，但是我得到的却是:

From what I know of Rails the html_safe should force HTML to be rendered properly, but instead what I get is this:

<ul class="navigation">[&quot;&lt;li class=\&quot;current\&quot;&gt;&lt;a href=\&quot;/games\&quot;&gt;Games&lt;/a&gt;&lt;/li&gt;&quot;, &quot;&lt;li class=\&quot;\&quot;&gt;&lt;a href=\&quot;/new\&quot;&gt;New&lt;/a&gt;&lt;/li&gt;&quot;, &quot;&lt;li class=\&quot;\&quot;&gt;&lt;a href=\&quot;/previous\&quot;&gt;Previous&lt;/a&gt;&lt;/li&gt;&quot;, &quot;&lt;li class=\&quot;\&quot;&gt;&lt;a href=\&quot;/settings\&quot;&gt;Settings&lt;/a&gt;&lt;/li&gt;&quot;]</ul> 

那么我是在做错什么，还是插件做错了?我知道该插件是在2.x天内写回的，这与我对HTML的处理方式有所不同，但我还不够了解.

So am I doing something wrong or is the plugin doing something wrong? I know that the plugin was written back in 2.x days which from what I know handled HTML a bit differently, but I just don't know enough.
