为什么在节点中插入数据后没有正确的响应？

Question

我正在尝试使用 Node 执行插入操作，但问题是数据被插入到数据库中但也抛出错误。下面是我的代码：

require('dotenv').config();
const db = require('../models/database');
const adminUser = db.AdminUser;
const errors = require('../config/errors').errors;
const jwt = require('jsonwebtoken');
const bcrypt = require('bcrypt');

exports.signUp = (req, res, next) => {
    console.log(req.body);
    bcrypt.hash(req.body.password, 12).then(hash => {
        const admin = new adminUser({
            emailId: req.body.emailId,
            firstName: req.body.firstName,
            middleName: req.body.middleName,
            lastName: req.body.lastName,
            mobileNumber: req.body.mobileNumber,
            userName: req.body.userName,
            password: hash,
            role: req.body.role,
            createdBy: req.body.createdBy
        });
        admin.save().then(result => {
            return res.status(200).send(error.OK);
        }).catch(err => {
            return res.status(500).send(error.SERVER_ERROR);
        });
    });
};

这里不是 then 块，而是 catch 块被触发并抛出此错误：

{
  emailId: 'abc@gmail.c',
  firstName: 'Avishek',
  middleName: '',
  lastName: 'Ray',
  mobileNumber: '123-456-7890',
  userName: 'avishek12',
  password: 'abc123',
  role: 'admin',
  createdBy: 'avi'
}
Executing (default): INSERT INTO `admin_users` (`id`,`emailId`,`firstName`,`middleName`,`lastName`,`mobileNumber`,`userName`,`password`,`role`,`createdBy`,`createdAt`) VALUES (DEFAULT,?,?,?,?,?,?,?,?,?,CURRENT_TIMESTAMP);

请帮帮我!!

根据您对常量的使用，您似乎应该在 .then() 和 .catch().

中使用 errors（带 S）

const errors = require('../config/errors').errors;

// ... code


    admin.save().then(result => {
        // reference errors require
        return res.status(200).send(errors.OK);
    }).catch(err => {
        // reference errors require
        return res.status(500).send(errors.SERVER_ERROR);
    });

用async/await写这个：

exports.signUp = async (req, res, next) => {
    try {
        const hash = await bcrypt.hash(req.body.password, 12);
        const admin = new adminUser({
            emailId: req.body.emailId,
            firstName: req.body.firstName,
            middleName: req.body.middleName,
            lastName: req.body.lastName,
            mobileNumber: req.body.mobileNumber,
            userName: req.body.userName,
            password: hash,
            role: req.body.role,
            createdBy: req.body.createdBy
        });
        await admin.save();
        return res.status(200).send(errors.OK); 
    } catch (err) {
        // console.log(err);
        return res.status(500).send(errors.SERVER_ERROR);
    }
};

为什么在节点中插入数据后没有正确的响应？

Why correct response not coming after data insert in Node?

orm

crud

node.js

sequelize.js
