请看看下面的代码：

var parties = Party.find({ email: email }, { email: 1, _id: 0 });

此查询返回3个文件。
现在我想给结果和字符串化这些文件：

response.json(parties);

我得到的错误，因为这里包含parties循环引用，并不会只包含纯数据，我需要在这里。

的问题是：

我怎么能在这里字符串化方法find()的结果呢？

能否请您添加的响应文件？ –

添加'缔约方'作为代码段。 –

您使用的平台是什么？我真的没有看到你想做什么。请给我看看Party.find（）的mongo shell响应。 –

我知道我的错误是什么。

MongoDB它的外壳和Mongoose API不一样。

find()方法需要不同的参数。

我需要这里的一个是：

Party.find({ 'email': email }, 'email', function (err, parties) { response.json(parties)});
