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

问题:

I'm getting a Unknown column 'userDetails.createdAt' in 'field list' When trying to fetch with association.

Using findAll without association works fine.

My code is as follows:

var userDetails = sequelize.define('userDetails', {     userId :Sequelize.INTEGER,     firstName : Sequelize.STRING,     lastName : Sequelize.STRING,     birthday : Sequelize.DATE });  var user = sequelize.define('user', {     email: Sequelize.STRING,     password: Sequelize.STRING });  user.hasOne(userDetails, {foreignKey: 'userId'});  user.findAll({include: [userDetails] }).success(function(user) {     console.log(user) });

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     } });
