請看看下面的代碼：

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

此查詢返回3個文件。
現在我想給結果和字符串化這些文件：

response.json(parties);

我得到的錯誤，因爲這裏包含parties循環引用，並不會只包含純數據，我需要在這裏。

的問題是：

我怎麼能在這裏字符串化方法find()的結果呢？

能否請您添加的響應文件？ –

添加'締約方'作爲代碼段。 –

您使用的平臺是什麼？我真的沒有看到你想做什麼。請給我看看Party.find（）的mongo shell響應。 –

我知道我的錯誤是什麼。

MongoDB它的外殼和Mongoose API不一樣。

find()方法需要不同的參數。

我需要這裏的一個是：

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