将猫鼬文档转换为json [英] Convert Mongoose docs to json

问题描述

我以这种方式将猫鼬文档作为json返回:

I returned mongoose docs as json in this way:

UserModel.find({}, function (err, users) {
    return res.end(JSON.stringify(users));
}

但是，还返回了user .__ proto__.没有它我怎么能回来?我试过了但是没用:

However, user.__proto__ was also returned. How can I return without it? I tried this but not worked:

UserModel.find({}, function (err, users) {
    return res.end(users.toJSON());    // has no method 'toJSON'
}

推荐答案

您也可以尝试mongoosejs的 lean():

You may also try mongoosejs's lean() :

UserModel.find().lean().exec(function (err, users) {
    return res.end(JSON.stringify(users));
}
