ES6 Question

I tried to refactor Andrews code and I have this:

instanceMethods: {
      publishedAt: () => dateFormat(this.createdAt, "dddd, mmmm dS, yyyy, h:MM TT"),

      shortDescription: () => this.body.length > 30 ? this.body.substr(0, 30) + "..." : this.body,

but when I go to the home page i get this error and assuming this is the issue---anyone see a problem with formatting here?

TypeError: C:\Users\crstu\Desktop\JSPROJ\sequelize_blog-start\views\articles\by_line.jade:4 2| = article.author 3| | |

4| = article.publishedAt()

Ran into this same problem new update in sequelize 4. this syntax worked for me

module.exports = (sequelize, DataTypes) => {
  var Article = sequelize.define('Article', {
    title: DataTypes.STRING,
    author: DataTypes.STRING,
    body: DataTypes.TEXT
  }, {});

  Article.associate = function(models) {
    // associations can be defined here

  Article.prototype.publishedAt = function(){
    return dateFormat(this.createdAt, "dddd, mmmm dS, yyyy, h:MM TT");

  Article.prototype.shortDescription = function(){
    return this.body.length > 30 ? this.body.substr(0, 30) + "..." : this.body;

  return Article;
