添加属性CouchDB的

Question

我已经安装了couchdb数据库使用couchrest一个ruby on rails应用程序中使用。

现在数据库中有10万左右的记录，我想添加一个字段来存储时间戳整数格式。
尝试在循环中更新它导致请求超时。

什么是一个新的领域/属性添加到CouchDB的最好方法是什么？

代码

pages = Page.all 
pages.each do |p| 
    p.update_attributes(:created_at_to_i => p.created_at.to_i) 
    puts p.created_at_to_i.inspect 
end 

跟踪

>> Page.update_timestamp

要添加您需要加载每个文件，修改它，并保存到数据库中的新属性。你可以使用bulk update api来做到这一点，但仅仅为了100k，我认为这是不值得的额外麻烦。

请发表您的更新脚本，并在发生超时时你得到的回溯。
