Question

我正在使用活动管理员在我的Rails 4.0应用程序中使用管理功能。我有一个列出

的用户表

id
姓名
电子邮件
电话号码

我也在列表顶部放了一个按钮。

action_item only: :index do
  link_to 'Export to CSV', '#'
end

我想导出用户ID名称＆amp;单击此按钮时，将电子邮件发送到csv文件。请帮我这样做

Answer 1

只需在admin

中添加部分即可

csv do
  column :id
  column :name
  column :email
end

同时检查active admin customize CSV

如果您打开链接，则会看到

行

column(:author) { |post| post.author.full_name }

它将作者姓名添加到帖子csv文件中，他可以添加你想要的任何字段

以下代码正常运作：

collection_action :import_csv, method: :get do
  users = User.all.order("id ASC")
  csv = CSV.generate( encoding: 'Windows-1251' ) do |csv|
    csv << [ "Id", "Name", "Gender", "Email", "Mobile number","Email Verified",
    "Mobile Verified", "Language Preference", "Counselling Preference", "Job Role Name",
    "Liked", "Disliked", "Favourited", "Shared", "Video Watched"]
    users.each do |u|
      email_verified = u.is_email_verified ? "Yes" : "No"
      mobile_verified = u.is_mobile_verified ? "Yes" : "No"
      counselling_preference = u.counselling_preference ? "Yes" : "No"
      userarry = [ u.id, u.name, u.gender, u.email, u.mobile_number,  email_verified,
      mobile_verified, u.language_preference, counselling_preference]
      csv << userarry + ["", "","","", "", ""]
    end
  end

  send_data csv.encode('Windows-1251'), type: 'text/csv; charset=windows-1251; header=present', disposition: "attachment; filename=accounting_report.csv"
end

action_item :add do
  link_to "Export to CSV", import_csv_admin_users_path, method: :get
end
