Activeadmin自定义操作和表单

Question

我想在我的Users activeadmin页面上实现一个自定义操作(notify_all),单击该页面时将显示一个表单,该表单在提交时将路由到另一个自定义操作(send_notification_to_all).到目前为止,我一直无法使第二部分工作.

管理员/ users.rb的:

ActiveAdmin.register User do

  action_item :only => :index do
    link_to 'Notify All', notify_all_admin_users_path
  end

  collection_action :notify_all, :method => :get do
    puts "notifying...."
    end

  collection_action :send_notification_to_all, :method => :post do
    puts "sending notification...."
  end



end

单击"通知全部"按钮时,将呈现以下视图.意见/管理/用户/ notify_all.html.erb

<form action="send_notification_to_all" method="post">
  <div><textarea rows="10" cols="100" placeholder="Enter message here"></textarea></div>
  <div><input type="submit"></div>
</form>

提交此表单后,我收到401 Unauthorized错误:

Started POST "/admin/users/send_notification_to_all" for 127.0.0.1 at 2014-02-12 14:08:27 -0600

   (20.3ms)  COMMIT

虽然主动管理员可以做我想做的事吗？

Answer 1

使用Rails,Formtastic或ActiveAdmin表单构建器可以完全避免该问题,因为它会自动为您呈现真实性令牌.

使用Formtastic的semantic_form_for表单构建器重写您的表单:

<%= semantic_form_for :notification, url: { action: :send_notification } do |f| %>

  <%= f.inputs do %>
    <%= f.input :content, as: :text, input_html: { placeholder: "Enter message here" } %>
  <%- end %>

  <%= f.actions %>
<%- end %>

有关更多详细信息,可能需要阅读Formtastic的文档.默认情况下,Formtastic包含在ActiveAdmin中.

Answer 2

在此处提出的类似问题中找到了答案。

我修改了表单以包含身份验证令牌，如下所示：

<form action="send_notification_to_all" method="post">
  <input type="hidden" name="authenticity_token" value="#{form_authenticity_token.to_s}">
  <div><textarea rows="10" cols="100" placeholder="Enter message here"></textarea></div>
  <div><input type="submit"></div>
</form>

这解决了这个问题。
