    <p>I'm creating a RESTful API with NodeJS, express, express-resource, and Sequelize that is used to manage datasets stored in a MySQL database.</p> <p>I'm trying to figure out how to properly update a record using Sequelize.</p> <p>I create a model:</p> <pre><code>module.exports = function (sequelize, DataTypes) { return sequelize.define('Locale', { id: { type: DataTypes.INTEGER, autoIncrement: true, primaryKey: true }, locale: { type: DataTypes.STRING, allowNull: false, unique: true, validate: { len: 2 } }, visible: { type: DataTypes.BOOLEAN, defaultValue: 1 } }) } </code></pre> <p>Then, in my resource controller, I define an update action.</p> <p>In here I want to be able to update the record where the id matches a <code>req.params</code> variable.</p> <p>First I build a model and then I use the <code>updateAttributes</code> method to update the record.</p> <pre><code>const Sequelize = require('sequelize') const { dbconfig } = require('../config.js') // Initialize database connection const sequelize = new Sequelize(dbconfig.database, dbconfig.username, dbconfig.password) // Locale model const Locales = sequelize.import(__dirname + './models/Locale') // Create schema if necessary Locales.sync() /** * PUT /locale/:id */ exports.update = function (req, res) { if (req.body.name) { const loc = Locales.build() loc.updateAttributes({ locale: req.body.name }) .on('success', id =&gt; { res.json({ success: true }, 200) }) .on('failure', error =&gt; { throw new Error(error) }) } else throw new Error('Data not provided') } </code></pre> <p>Now, this does not actually produce an update query as I would expect.</p> <p>Instead, an insert query is executed:</p> <pre><code>INSERT INTO `Locales`(`id`, `locale`, `createdAt`, `updatedAt`, `visible`) VALUES ('1', 'us', '2011-11-16 05:26:09', '2011-11-16 05:26:15', 1) </code></pre> <p>So my question is: What is the proper way to update a record using Sequelize ORM?</p>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
