架构中的ENUM值可以在模型的rawAttributes属性中找到。

var Model = sequelize.define('model', {
  states: {
    type:   Sequelize.ENUM,
    values: ['active', 'pending', 'deleted']
  }
});

console.log(Model.rawAttributes.states.values);
// logs ['active', 'pending', 'deleted'] in console

sequelize.define('model', {
  states: {
    type:   Sequelize.ENUM('active', 'pending', 'deleted')
  }
})

像这样创建JavaScript枚举对象

module.exports.BookingStatus = Object.freeze({
    Done : 'Done',
    Pending : 'Pending',
    Rejected : 'Rejected'
});

接下来，创建具有枚举的sequalize Schema

const Booking = sequalize.define(
        'booking',
        {
            customerId : DataTypes.STRING,
            bookingStatus : {
               type : DataTypes.ENUM,
               values : Object.values(this.BookingStatus),
               defaultValue :  this.BookingStatus.Pending
            },
        },
        {
            timestamps: true,
        }
    );
