Is there a simple way to make Sequelize return it's date/time fields in a particular format?

Question

We need to have sequelize return dates in a particular format, not the default one. As far as I can tell, there is no way to set that up in options, or any other way. Short

Answer 1

You can, use the Sequelize fn method. From the API Reference, the fn function will help create an object representing a SQL function in your query.

For example:

model.findAll({
  attributes: [
      'id',
      [sequelize.fn('date_format', sequelize.col('date_col'), '%Y-%m-%d'), 'date_col_formed']
  ]})
  .then(function(result) {
    console.log(result);
  });

Will return data values:

[
  {"id": 1, "date_col_formed": "2014-01-01"},
  {"id": 2, "date_col_formed": "2014-01-02"}
   // and so on...
