The problem is probably with how you are setting you association, kindly mention your strategy.

Following is working fine if you use the express index.js file setup and then query http://docs.sequelizejs.com/en/1.7.0/articles/express/

'use strict';
module.exports = function(sequelize, DataTypes) {
  var customer = sequelize.define('customer', {
    customernumber: DataTypes.STRING(30), //remove
    customerspecificationid: DataTypes.INTEGER,
    customertypeid: DataTypes.INTEGER,
    sportid: DataTypes.INTEGER,
    customername: DataTypes.STRING(20), //remove
    address: DataTypes.STRING(30),
    city: DataTypes.STRING(30),
    state: DataTypes.STRING(30),
    zipcode: DataTypes.STRING(30),
    ordercomplete: DataTypes.BOOLEAN,
    isactive: DataTypes.BOOLEAN
  }, {
      associate: function(models) {
          // associations can be defined here
        models.customer.hasMany(models.order);
      }
  });

  customer.hook('afterCreate', function(cust, options) {
      //generate the customer number

        return customer.update({ customernumber: custnumber }, {
        where: {
          id: cust.id
        }
      });
  });

  return customer;
};


'use strict';
module.exports = function(sequelize, DataTypes) {
  var order = sequelize.define('order', {
    ponumber: DataTypes.STRING(30), //remove
    orderdate: DataTypes.DATE,
    shippingmethod: DataTypes.STRING(30),
    shippingterms: DataTypes.STRING(30),
    deliverydate: DataTypes.DATE,
    paymentterms: DataTypes.STRING(30),
    overridediscount: DataTypes.BOOLEAN,
    shippingaddress: DataTypes.STRING(30),
    shippingcity: DataTypes.STRING(30),
    shippingstate: DataTypes.STRING(20),
    shippingzipcode: DataTypes.STRING(10),
    isactive: DataTypes.BOOLEAN
  }, {
      associate: function(models) {
        // associations can be defined here
        models.order.belongsTo(models.user);
        models.order.belongsTo(models.customer);
      }
  });

  order.hook('afterCreate', function(ord, options) {
      //generate po number

      return order.update({ ponumber: ponumbr }, {
        where: {
          id: ord.id
        }//,
        //transaction: options.transaction
      });
  });

  return order;
};

'use strict';

module.exports = function(sequelize, DataTypes) {
  var user = sequelize.define('user', {
    username: DataTypes.STRING(30), //remove
    password: DataTypes.STRING(255),
    emailaddress: DataTypes.STRING(255),
    firstname: DataTypes.STRING(30),
    middlename: DataTypes.STRING(30), //remove
    lastname: DataTypes.STRING(30),
    approve: DataTypes.BOOLEAN,
    roles: DataTypes.STRING(50),
    isactive: DataTypes.BOOLEAN
  }, {
    classMethods: {
      associate: function(models) {
        // associations can be defined here
        models.user.hasMany(models.order);
      }
    }
  });

  user.hook('afterCreate', function(usr, options) {
      //hash the password

      return user.update({ password: passwd }, {
        where: {
          id: usr.id
        }
      });
  });

  return user;
};

// index.js file where you shall associate the routes

var fs        = require('fs')
    , path      = require('path')
    , Sequelize = require('sequelize')
    , lodash    = require('lodash')
    , sequelize = new Sequelize('sequelize_test', 'root', 'root')
    , db        = {} 

  fs.readdirSync(__dirname)
    .filter(function(file) {
      return (file.indexOf('.') !== 0) && (file !== 'index.js')
    })
    .forEach(function(file) {
      var model = sequelize.import(path.join(__dirname, file))
      db[model.name] = model
    })

  Object.keys(db).forEach(function(modelName) {
    if (db[modelName].options.hasOwnProperty('associate')) {
      db[modelName].options.associate(db)
    }
  })
  // sequelize.sync({force: true})
  module.exports = lodash.extend({
    sequelize: sequelize,
    Sequelize: Sequelize
  }, db)

Put the above db code in respective files in db folder or whatever you like to name it and then you can use your query

var db = require('./db');

db.order.find({
            where: { id: 0 },
            include: [ db.customer, db.user ]
        })
        .then(function(order){
            console.log(order)
        })
