Question

我的代码如下所示：

  let time = db.Sequelize.DataTypes.NOW;

  console.log('generated time is' + time);

db.js

const Sequelize = require('sequelize');
require('dotenv').config();


const db = {};


var sequelize = new Sequelize({
    host: process.env.DB_HOST,
    database: process.env.DB_NAME,
    username: process.env.DB_USER_NAME,
    password: process.env.DB_PASSWORD,
    dialect: process.env.DB_TYPE,
    port: process.env.DB_PORT,
    pool: {
        max: 5,
        min: 0,
        acquire: 30000,
        idle: 10000
    },
    operatorsAliases: false
});

sequelize
    .authenticate()
    .then(() => {
        console.log('connected to database successfully')
    })


sequelize.sync({
    force: false
})


db.Sequelize = Sequelize;
db.sequelize = sequelize;

我得到的输出是

generated time is  function NOW() {
  if (!(this instanceof NOW)) return new NOW();
}

如何生成带时间戳的值？

Answer 1

这绝对是正确的方式。为什么你认为它应该返回一个时间戳？它不应该。如果您想获得timestamp，请运行：

new Date().getTime()

Answer 2

在迁移中，可以使用文字。这将对您有帮助，我也面临此类问题。这有效：

defaultValue: Sequelize.literal('CURRENT_TIMESTAMP')

sequelize datatypes.NOW函数不生成时间戳
