Avoid created_at and updated_at being auto generated by sequelize

Question

How do I define a model for which created_at and updated_at are provided rather than generated?

I'm importing data from somewhere that already has data for created_at and updated_at fields that I would like to preserve rather than generating whenever the object is created/updated by sequelize (our secondary store).

I've tried every likely permutation of model definition and options to get this to work and still sequelize overwrites my fields with it's own timestamps: {silent: true}, etc...

To be clear, the input data has createdAt and updatedAt and I'd like to use sequelize's bulkCreate(), etc such that input values provided are used and stored on the model as created_at and updated_at rather than generated by sequelize.

This is my current model definition:

const Lead = sequelize.define('lead', {   objectId: {     type: Sequelize.STRING,     field: 'objectId',     primaryKey: true,     allowNull: false   },   firstName: {     type: Sequelize.STRING,     field: 'first_name'   },   lastName: {     type: Sequelize.STRING,     field: 'last_name'   },   phoneNumber: {     type: Sequelize.STRING,     field: 'phone_number'   },   createdAt: {     type: Sequelize.DATE,     field: 'created_at',   },   updatedAt: {     type: Sequelize.DATE,     field: 'updated_at'   } }, {   freezeTableName: true, // Model tableName will be the same as the model name   timestamps: false,   underscored: true }); 

Answer 1

The option is

timestamps: false, 

Where timestamps is written fully lowercase

Update:

From looking at the code of the bulkCreate() function, it looks that it always updates the timestamps, so, without a patch this is not possible right now
