我正在尝试使用以下代码使用css设置rails链接的样式:
<%= link_to "Learn More", :controller => "menus", :action => "index", :class => "btn btn-inverse" %>
Run Code Online (Sandbox Code Playgroud)
我希望这会创建一个如下所示的链接:
<a href="menus/" class="btn btn-inverse">Learn More</a>
Run Code Online (Sandbox Code Playgroud)
相反,rails正在渲染这个 -
<a href="/menus?class=btn+btn-inverse">Learn More</a>

有没有其他人有这个问题/知道我做错了什么?我知道我可以通过手动创建锚标记而不是使用帮助程序来避免这个问题,但我想知道是否有办法将css类信息传递给帮助程序本身.我正在使用Rails 3.2.6.
谢谢!
