Sequelize createdAt

This is my current model definition: const Lead = sequelize.define ('lead', { objectId: { type: Sequelize By default, Sequelize will add the attributes createdAt and updatedAt to your model so you will be able to know when the database entry went into the db and when it was updated last. Note that if you are using Sequelize migrations you will need to add the createdAt and updatedAt fields to your migration definition By default, Sequelize automatically adds the fields createdAt and updatedAt to every model, using the data type DataTypes.DATE. Those fields are automatically managed as well - whenever you use Sequelize to create or update something, those fields will be set correctly How to format the createdAt and updatedAt columns' values into something useable like YYYY-MM-DD. If possible: Provide some suggestion how we can enhance the docs I had to use the following dialect options to make sure I didn't get weird date formatting (why the hell would you show my timezone in the format as Central European?) module.exports = { up: function(migration, DataTypes, done) { // add altering commands here, calling 'done' when finished migration.createTable( 'mytable', { id: { type: DataTypes.INTEGER, primaryKey: true, autoIncrement: true }, /** some more fields in here, not really relevant **/ created_at: { type: DataTypes.DATE, defaultValue: DataTypes.NOW, allowNull: false }, updated_at: { type: DataTypes.DATE, defaultValue: DataTypes.NOW, allowNull: false } } ); done(); }, down: function(migration.

  1. Sequelize provides the Model.bulkCreate method to allow creating multiple records at once, with only one query. The usage of Model.bulkCreate is very similar to Model.create, by receiving an array of objects instead of a single object
  2. Timestamps disables/enables the fields altogether, underscore enabled/disabled camelizing the field names (set this to true if you want created_at instead of createdAt). For example: sequelize.define('User', { username: Sequelize.STRING }, { underscored: true }) Hope this helps. Copy link
  3. Each field can either be a string containing the name of the field, a sequelize object (e.g sequelize.fn), or an object with the following attributes: attribute (field name), length (create a prefix index of length chars), order (the direction the column should be sorted in), collate (the collation (sort order) for the column) options.createdAt
