Sequelize - How do I fix "DataTypes is not defined"?

Question

I'm trying to have a model in sequelize generate a unique ID using DataTypes.UUID. This throws an error when I serve up my application

ReferenceError: DataTypes is not defined

Here's my code

var Sequelize = require('sequelize');
var sequelize = new Sequelize('uppersphere', '****', '***', {
  logging: false
});
...
var Peak = sequelize.define('peak', {
  id: {
    type: DataTypes.UUID,
    defaultValue: DataTypes.UUIDV1,
    primaryKey: true
  },

Here's the documentation

sequelize.define('model', {
    uuid: {
      type: DataTypes.UUID,
      defaultValue: DataTypes.UUIDV1,
      primaryKey: true
    }
  })

The obvious answer is that it's not my code, but there's some require() that I need. However, I don't see any documentation on what to require to get DataTypes.

Answer 1

The Data Types can be accessed via the Sequelize object:

var Sequelize = require('sequelize');
var Peak = sequelize.define('peak', {
  id: {
    type: Sequelize.UUID,
    defaultValue: Sequelize.UUIDV1,
    primaryKey: true
  },

DataTypes is a just a convenience class which you can import directly if needed:

var DataTypes = require('sequelize/lib/data-types');

Also, the model files are imported with DataTypes as a second argument
