Sequelize Unknown column '*.createdAt' in 'field list'

I think the error is that you have timestamps enabled in sequelize, but your actual table definitions in the DB do not contain a timestamp column.

When you do user.find it will just do SELECT user.*, which only takes the columns you actually have. But when you join, each column of the joined table will be aliased, which creates the following query:

SELECT `users`.*, `userDetails`.`userId` AS `userDetails.userId`,`userDetails`.`firstName` AS `userDetails.firstName`,`userDetails`.`lastName` AS `userDetails.lastName`, `userDetails`.`birthday` AS `userDetails.birthday`, `userDetails`.`id` AS `userDetails.id`, `userDetails`.`createdAt` AS `userDetails.createdAt`, `userDetails`.`updatedAt` AS `userDetails.updatedAt` FROM `users` LEFT OUTER JOIN `userDetails` AS `userDetails` ON `users`.`id` = `userDetails`.`userId`;

The fix would be to disable timestamps for either the userDetails model:

var userDetails = sequelize.define('userDetails', {    userId :Sequelize.INTEGER,    firstName : Sequelize.STRING,    lastName : Sequelize.STRING,    birthday : Sequelize.DATE}, {    timestamps: false});

or for all models:

var sequelize = new Sequelize('sequelize_test', 'root', null, {    host: "127.0.0.1",    dialect: 'mysql',    define: {        timestamps: false    }});

I got the same error when migrating our project from laravel to featherjs. Tables are having column names created_at, updated_at instead of createdat, updatedat. I had to use field name mapping in Sequelize models as given below

  const users = sequelize.define('users', {     id: {         type: Sequelize.INTEGER,         primaryKey: true     },     createdAt: {         field: 'created_at',         type: Sequelize.DATE,     },     updatedAt: {         field: 'updated_at',         type: Sequelize.DATE,     },     ..     ..     ..     ..

I got same error,two solutions：

1. when create table, add created_at and updated_at column.

CREATE TABLE `users` (  `id` int(11) NOT NULL AUTO_INCREMENT COMMENT 'primary key',  `name` varchar(30) DEFAULT NULL COMMENT 'user name',  `created_at` datetime DEFAULT NULL COMMENT 'created time',  `updated_at` datetime DEFAULT NULL COMMENT 'updated time',  PRIMARY KEY (`id`)) ENGINE=InnoDB DEFAULT CHARSET=utf8mb4 COMMENT='user';

2. disable timestamps

const Project = sequelize.define('project', {   title: Sequelize.STRING,   description: Sequelize.TEXT },{   timestamps: false })
