title: ExpressJS + Sequelize er_bad_field_error: Unknown column in fieldlist
body: <p>Using the following model file in conjunction with Sequelize, this code runs without error and allows me to perform an insert:</p>
  
  <pre><code>var crypto = require('crypto');
  
  module.exports = function(sequelize, DataTypes) {
  
  var User = sequelize.define('User', 
      {
          title: DataTypes.STRING,
          name: DataTypes.STRING,
          email: DataTypes.STRING,
          username: DataTypes.STRING,
          hashedPassword: DataTypes.STRING,
          provider: DataTypes.STRING,
          salt: DataTypes.STRING, 
          facebookUserId: DataTypes.INTEGER,
          twitterUserId: DataTypes.INTEGER,
          twitterKey: DataTypes.STRING,
          twitterSecret: DataTypes.STRING,
          github: DataTypes.STRING,
          openID: DataTypes.STRING
      },
  ...
  )
  </code></pre>
  
  <p>However, when I try to manually add my own fields of interest, i.e. adding a ZIP code field as below:</p>
  
  <pre><code>module.exports = function(sequelize, DataTypes) {
  
  var User = sequelize.define('User', 
      {
          title: DataTypes.STRING,
          name: DataTypes.STRING,
          email: DataTypes.STRING,
          username: DataTypes.STRING,
          hashedPassword: DataTypes.STRING,
          provider: DataTypes.STRING,
          salt: DataTypes.STRING, 
          facebookUserId: DataTypes.INTEGER,
          twitterUserId: DataTypes.INTEGER,
          twitterKey: DataTypes.STRING,
          twitterSecret: DataTypes.STRING,
          github: DataTypes.STRING,
          openID: DataTypes.STRING,
          ZIP: DataTypes.INT
      },
  </code></pre>
  
  <p>the following error propagates:</p>
  
  <pre><code> SequelizeDatabaseError: ER_BAD_FIELD_ERROR: Unknown column 'title' in 'field list'
  </code></pre>
  
  <p>Why am I not allowed to add fields within the models to be able to access them from the controller?</p>
