添加：具有：controller和：方法的link_to类

Question

下面的内容有效，但我可以为它添加一个课程。

<%= link_to "Cancel My Subscription", {:controller => :charges, :action => :cancel}, {:method => :post } %>

这不起作用：

<%= link_to "Cancel My Subscription", {:controller => :charges, :action => :cancel}, {:method => :post }, :class => "btn" %>

Answer 1

向链接添加类的方法如下：

<%= link_to "Cancel My Subscription", { URL_FOR PARAMS HERE }, :controller => 
        :charges, :action => :cancel, :method => :post, :class => "btn" %>

希望这有帮助。
