sequelize table without column 'id'

I have the following sequelize definition of a table:

AcademyModule = sequelize.define('academy_module', {
        academy_id: DataTypes.INTEGER,
        module_id: DataTypes.INTEGER,
        module_module_type_id: DataTypes.INTEGER,
        sort_number: DataTypes.INTEGER,
        requirements_id: DataTypes.INTEGER
    }, {
        freezeTableName: true
});

As you can see there is not an id column in this table. However when I try to insert it still tries the following sql:

 INSERT INTO `academy_module` (`id`,`academy_id`,`module_id`,`sort_number`) VALUES (DEFAULT,'3',5,1);

How can I disable the id function it clearly has?

Solution 1:

If you don't define a primaryKey then sequelize uses id by default.

If you want to set your own, just use primaryKey: true on your column.

AcademyModule = sequelize.define('academy_module', {
    academy_id: {
        type: DataTypes.INTEGER,
        primaryKey: true
    },
    module_id: DataTypes.INTEGER,
    module_module_type_id: DataTypes.INTEGER,
    sort_number: DataTypes.INTEGER,
    requirements_id: DataTypes.INTEGER
}, {
    freezeTableName: true
});

Solution 2:

If you want to completely disable the primary key for the table, you can use Model.removeAttribute. Be warned that this could cause problems in the future, as Sequelize is an ORM and joins will need extra setup.

const AcademyModule = sequelize.define('academy_module', {
    academy_id: DataTypes.INTEGER,
    module_id: DataTypes.INTEGER,
    module_module_type_id: DataTypes.INTEGER,
    sort_number: DataTypes.INTEGER,
    requirements_id: DataTypes.INTEGER
}, {
    freezeTableName: true
});
AcademyModule.removeAttribute('id');

Solution 3:

For a composite primary key, you should add "primaryKey: true" to all columns part of the primary key. Sequelize considers such columns to be part of a composite primary key.
