Ruby on rails 4 Rails管理-更新前的消息

我使用rails\u admin

---

有人知道我如何在更新前显示确认消息（带有操作）吗

我将创建自定义操作或覆盖现有操作。大概是这样的：

class Update2
  RailsAdmin::Config::Actions.register(self)
  register_instance_option :visible? do
    # 
  end
  register_instance_option :link_icon do
    # your icon here
  end
  register_instance_option :http_methods do
    [:get, :post]
  end
  register_instance_option :controller do
    Proc.new do
      if request.post?
        @object.update
        flash[:notice] = "Updated #{@object.name}."
        redirect_to show_path
      end
    end
  end
end

然后创建一个页面app/views/rails_admin/main/update2.html.haml

%h3 
  = "Are you sure you want to update '#{@object.name}'
= link_to 'Update', update2_path, method: 'post', class: "btn btn-danger"
= link_to 'Cancel', show_path, class: "btn btn-primary"

当您单击Update2时，您将通过GET进入页面。然后在POST上它将实际更新
