我需要插入电子邮件作为不同的记录的阵列到我的联系人表。如何才能做到这一点。

I need to insert a array of emails as different records into my contacts table. How can this be done.

Eg: @email = ["a@b.com", "c@d.com", "e@f.com", ... ]

我不想使用。

I dont want to use.

  @email.each do |email|
     @contact = Contact.new
     @contact.email = email
     @contact.save
  end

这触发N个插入张塌塌米。我只是需要一个单一的插入查询，插入这些值。如何在轨3.0.9（理想情况下的MySQL）这样做。请帮忙

This cause n insert quires. I just need a single insert query to insert these values. How can this be done in rails 3.0.9 (and ideally MySQL). Please help

推荐答案

ActiveRecord的导入实现AR＃进口

ActiveRecord的导入是使用ActiveRecord的批量插入数据的库。

activerecord-import is a library for bulk inserting data using ActiveRecord.

看看它是如何工作的：

books = []
10.times do |i| 
  books << Book.new(:name => "book #{i}")
end
Book.import books
