MongoDB 更新查询默默失败

发布于 2024-10-17 14:57:51 字数 800 浏览 2 评论 0原文

我有一个在 MongoDB 之上使用 Mongoid 的应用程序，并且更新悄无声息地失败了。

代码如下所示：

# Are we getting a new attribute? Yes we are!
p "attr first name = #{@attributes['first_name']}"

if user.update_attributes!(@attributes)
   u = User.find(params[:id]).to_json
end

这段代码中没有抛出异常。因此，我查看了 MongoDB 日志，并根据 mongo 尝试执行的操作构建了此查询：

db.users.update({ "_id": "4d5561276ce886c496000001" }, { $set: { "first_name": "Erinamodobo" } }, false);

现在这不会导致任何异常，但是当我获取本应使用此查询更新的记录时：

db.users.find({"email":"[email protected]"})

我看到“first_name”属性尚未更新。

知道为什么会发生这种情况吗？听起来像是一些愚蠢的事情。

谢谢！

I have an app using Mongoid on top of MongoDB and an update is failing silently.

The code looks like this:

# Are we getting a new attribute? Yes we are!
p "attr first name = #{@attributes['first_name']}"

if user.update_attributes!(@attributes)
   u = User.find(params[:id]).to_json
end

No exception is thrown in this code. So I looked at my MongoDB log and constructed this query based on what mongo is trying to do:

db.users.update({ "_id": "4d5561276ce886c496000001" }, { $set: { "first_name": "Erinamodobo" } }, false);

Now this does not cause any exceptions but when I grab the record that was supposed to be updated with this query:

db.users.find({"email":"[email protected]"})

I see that the "first_name" attribute has not been updated.

Any idea why this could be happening? Sounds like something stupid.

Thanks!

您需要找出

user.update_attributes!(@attributes)

实际在做什么。这可能是 Mongoid 的问题。配置 Mongoid 时，您可以设置记录器。在那里您应该能够看到驱动程序正在向 MongoDB 写入什么内容，这应该有助于回答您的问题。下一个最好的办法是将您的代码发布到 Mongoid 邮件列表 (http://groups.google.com/group/mongoid)，一直使用 Mongoid 的人们可能会知道发生了什么。

You need to find out what

user.update_attributes!(@attributes)

is actually doing. This could be an issue with Mongoid. When you configure Mongoid, you can set up a logger. There you should be able to see what the driver is writing to MongoDB, and that should help answer your question. The next best thing is to post your code to the Mongoid mailing list (http://groups.google.com/group/mongoid) where people who work with Mongoid all the time will probably know what's going on.
