onUpdate not working

onUpdate key in model definition for a column doesn’t update the column value when updated

Sequelize Version : 4.41.2 Node Version : 8.15.0 Dialect : mysql

I have a table test as described below:

+--------------+--------------------------------+------+-----+---------+----------------+
| Field        | Type                           | Null | Key | Default | Extra          |
+--------------+--------------------------------+------+-----+---------+----------------+
| id           | bigint(20)                     | NO   | PRI | NULL    | auto_increment |
| is_active    | tinyint(1)                     | YES  |     | 1       |                |
| created_at   | datetime                       | NO   |     | NULL    |                |
| updated_at   | datetime                       | NO   |     | NULL    |                |
+--------------+--------------------------------+------+-----+---------+----------------+

and this is its model definition in my code:

sequelize.define("test", {
    id: {
      type: Sequelize.BIGINT,
      primaryKey: true,
      autoIncrement: true,
    },
    is_active: {
      type: Sequelize.BOOLEAN,
      defaultValue: true,
      allowNull: false
    },
    created_at: {
      type: Sequelize.DATE,
      defaultValue: Sequelize.NOW,
      allowNull: false,
      get: function() {
        return new Date(this.getDataValue('created_at')).valueOf();
      }
    },
    updated_at: {
      type: Sequelize.DATE,
      defaultValue: Sequelize.NOW,
      onUpdate : Sequelize.NOW,
      allowNull: false,
      get: function() {
        return new Date(this.getDataValue('updated_at')).valueOf();
      }
    }
  });

When I try to update any column such as is_active the updated_at field value doesn’t change in the database even when onUpdate is mentioned.

Ideally it should update, but it doesn’t.

@rajat12a I have a weird request - can you please test again using camelCase instead of snake_case for all your fields? I have a feeling this might be related to several weird things happening with underscored fields in sequelize v5.
