title: How to add column in Sequelize existing model?
body: <p>I have added a model and a migration file using this command </p>
  
  <pre><code>node_modules/.bin/sequelize model:generate --name User --attributes firstName:string,lastName:string,email:string
  </code></pre>
  
  <p>Now I wanted to add few more fields like gender and age in to the existing table(model). I changed model manually and fire this command </p>
  
  <pre><code>node_modules/.bin/sequelize db:migrate
  </code></pre>
  
  <p>But it is responding that "No migrations were executed, database schema was already up to date.
  "</p>
  
  <p><strong>User.js</strong> </p>
  
  <pre><code>'use strict';
  module.exports = (sequelize, DataTypes) =&gt; {
    var User = sequelize.define('User', {
      firstName: DataTypes.STRING,
      lastName: DataTypes.STRING,
      email: DataTypes.STRING
    }, {});
    User.associate = function(models) {
      // associations can be defined here
    };
    return User;
  };
  </code></pre>
  
  <p>Thank you in advance :) </p>
