activeadmin：member_action 上的参数数量错误（1 为 0）

Question

我正在使用 active admin 构建我的 RoR 应用程序管理界面，遇到异常我一直在尝试设置自定义操作：

ActiveAdmin.register Deal do
 [:cancel, :release].each do |event|
   member_action event , method: :patch do |deal|
    deal.send :"#{event}!"
    redirect_to admin_deal_path(deal), notice: "Your event was #{deal.current_state}"
   end

   action_item event, only: :show do
     link_to event, url_for(action: event), method: :patch
   end
 end
end

事件链接在页面上显示良好，但单击其中一个链接时出现以下异常：

ArgumentError (wrong number of arguments (0 for 1)):

admin/deal.rb 的第 46 行是调用 member_action 的行，似乎 activeadmin 方法在某处以某种方式被覆盖，或者有其他明显的我没有看到的东西。 ..

知道它可能来自哪里吗？ 我正在使用 cancancan、devise 和 responders。

提前致谢

我的错误是将一个变量传递给 member_action 块，该实例似乎可以通过 resource 帮助程序获得

member_action :cancel, method: :patch do
  resource.cancel!
  redirect_to admin_deal_path(resource) 
end

activeadmin：member_action 上的参数数量错误（1 为 0）

activeadmin : wrong number of arguments (0 for 1) on member_action
