添加：類link_to具有：控制器和：方法

Question

下面的工作，但我會撒謊添加一個類。

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

這不是工作：

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

Answer 1

的方式來增加一類的鏈接如下：

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

希望這有助於。
