title: adding new column to the existing table in sequelize
body: <p>I have a table in the database and now I want to add two new columns to it.
  I have altered the Table using the <code>MYSQL cmd line</code> and also added the newly added columns into the <code>Sequelize</code> model.</p>
  
  <p>But when I fire the insert query, it still fires the query with previous fields and does not adds up the newly added columns to it.</p>
  
  <p>Here is my data Model:</p>
  
  <pre><code>var Observation = sequelize.define('observation_details', {
    obv_id: {
      type: Sequelize.INTEGER,
      primaryKey: true
    },
    obv_source: Sequelize.STRING,
    obv_waveband: Sequelize.INTEGER,
    prpsl_id: Sequelize.INTEGER,
    obv_ra: Sequelize.DOUBLE,              //newly added column
    obv_dec: Sequelize.DOUBLE              // newly added column
  }, {
    tableName: 'observation_details',             
    timestamps: false                             
  });
  </code></pre>

  <p>Here in the table <code>obv_ra</code> and <code>obv_dec</code> are already added..!</p>
  
  <p>This is the Insert Query:</p>
  
  <pre><code>Observation.create({
    obv_source: req.body.obvDetails[i].source,
    obv_waveband: req.body.obvDetails[i].waveband,
    prpsl_id: proposalId,
    obv_ra: req.body.obvDetails[i].ra,
    obv_dec: req.body.obvDetails[i].dec
  })
  </code></pre>
  
  <p>adding <code>Sequelize.sync({force:false})</code> results in :</p>
  
  <blockquote>
    <p>Executing (default): CREATE TABLE IF NOT EXISTS observation_details (obv_id INTEGER , obv_source VARCHAR(255), obv_waveband INTEGER, prpsl_id INTEGER, obv_ra DOUBLE PRECISION, obv_dec DOUBLE PRECISION, PRIMARY KEY (obv_id)) ENGINE=InnoDB;</p>
  </blockquote>
  
  <p>but still the query fired is :</p>
  
  <blockquote>
    <p>Executing (default): INSERT INTO observation_details (obv_id,obv_source,obv_waveband,prpsl_id) VALUES (NULL,dgf,2,19);</p>
  </blockquote>
  
  <p>Is there any way to work this out without using <code>Migrations</code>?</p>
