Sequelize Migration Remove Primary Key

Question

I was reading through the sequelize documentation, and I was unsure whether there was a way to remove a primary key constraint on a column.

Here is the most relevant link: http://docs.sequelizejs.com/en/latest/docs/migrations/#changecolumntablename-attributename-datatypeoroptions-options

Answer 1

What worked for me was dropping to sql, not sure if I was doing something wrong but nothing else I tried seemed to work.

From: https://github.com/sequelize/sequelize/issues/313

up: function (queryInterface, Sequelize) {
    return queryInterface.sequelize.query('ALTER TABLE my_table DROP PRIMARY KEY');
}
