Active Admin导出为CSV文件

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。我有一个用户表，列出

• ID
• 名
• 电子邮件
• 手机没有

我也提上了名单这样的顶部的按钮。

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

我想将用户ID名称&电子邮件导出为CSV文件，当我点击这个按钮。请帮我做这个

Answer 1

只需添加部分内部管理

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

检查也active admin customize CSV

如果你打开链接，你会看到一行

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

它增加了作者名字进入后csv文件，他的方式，你可以添加任何你想要的领域
