Question

我想在默认情况下将mongoose中的created_by字段设置为自动生成功能。但是我正面临麻烦。我无法将req.body.username设置为默认状态，我也已经尝试创建变量，并称它仍然不起作用。这是我在模型上的代码：

    const mongoose = require('mongoose');
const Schema = mongoose.Schema;
const { findByUsername } = require('../services/userService');
const bcrypt = require('bcrypt');

const username = req.body.username;

created_by: {
        type: String,
        required: [true, "This field is required"],
        default: username

},
    updated_by: {
        type: String,
        required: [false, "This field is required"]
    }
}, {collection: 'ticket'});

const Ticket = mongoose.model("Ticket", TicketSchema);
module.exports = {Ticket, TicketSchema};

我想要（created_by）字段从用户名接收值，我已经尝试通过controller.js及其工作来获取用户名值。所以我想根据用户当前登录的用户名来设置created_by字段的默认值。

这是我已经在controller.js中尝试过的代码

    module.exports = {
GetUsername : async function (req, res, next) {
        errors = {};
        const username = req.body.username;
        return res.status(200).json({"status": "success", "data": username});


    }
}

有人可以告诉我如何在猫鼬模式中获取req.body.user吗？
