sequelize table without column 'id'
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');
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
});
If your model does not have an ID column you can use Model.removeAttribute('id'); to get rid of it.
See http://docs.sequelizejs.com/en/latest/docs/legacy/
So in your case it would be
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');
Note:
You seem to be making a join table. Consider making academy_id
and module_id
primary keys. That way the same link will not be able to appear multiple times, and the database will not create a hidden id column in vain.
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.
