@nswbmw 你的github上第六章好像有问题

https://github.com/nswbmw/N-blog/wiki/%E7%AC%AC6%E7%AB%A0–%E5%AE%9E%E7%8E%B0%E7%95%99%E8%A8%80%E5%8A%9F%E8%83%BD

collection.update({
        "name": name,
        "time.day": day,
        "title": title
      }, {
        $push: {"comments": comment}
      } , function (err, result) {
          mongodb.close();
          callback(null);
      });

这样插不入，是不是要用findAndModify
