CouchDb自动时间戳 [英] CouchDb automatic timestamps

问题描述

我正在使用CouchDB实现消息应用程序。我想将时间戳记应用于每封邮件。我发现一些参考资料表明我应该为此使用文档更新处理程序。就地更新似乎是正确的事情。但是我将从哪里获得时间戳记？

I'm implementing a message application using CouchDB. I want to apply timestamps to each message. I found some references indicating that I should use document update handlers for this. In place updates seem like the right thing. But where would I get a timestamp from? Is it in the req object somewhere?

{
  updates: {
    "in-place" : function(doc, req) {
      doc.timestamp = "???";
      var message = "set timestamp to "+doc.timestamp;
      return [doc, message];
    }
  }
}

推荐答案

答案是使用javascript的日期函数。

The answer is to use javascript's date functions.

{
  updates: {
    "in-place" : function(doc, req) {
      doc.timestamp = new Date().getTime();
      var message = "set timestamp to "+doc.timestamp;
      return [doc, message];
    }
  }
}

不幸的是，将此更新更新为下一个问题是来自jcouchdb的触发器。

Unfortunately, getting this update to trigger from jcouchdb is the next problem.
