Ruby on rails ：方法=>；删除不工作的路由

删除路径的这个按钮似乎被路由到我的友谊#以某种方式创建操作：

<%= button_to "Unfriend", unfriend_path(@user), :method => :delete, :class => "btn primary", :remote => true %>

这是服务器日志

下面是呈现的HTML（使用隐藏方法delete form）

按钮不支持删除选项，只支持post和get。（来源：）

确保生成的表单中有一个名为_method的隐藏字段，其值为delete

---

如果没有生成，可以使用Javascript动态插入它。

因此我尝试在路由文件中切换这些路由的顺序……现在它调用销毁操作就可以了。这里有些不对劲，但我不确定如何修复它，使两个命名路由都能工作。生成的html中已经有了这个。我现在一直在胡闹，把它改成资源有助于删除路由，但无助于创建路由。
