Type Parameters



_autoGenerated?: boolean

This attribute is added by sequelize. Do not use!

allowNull?: boolean

If false, the column will have a NOT NULL constraint, and a not null validation will be run before an instance is saved.


attributeName: string

The name of the attribute (JS side).

autoIncrement?: boolean

Is this field an auto increment field

autoIncrementIdentity?: boolean

If this field is a Postgres auto increment field, use Postgres GENERATED BY DEFAULT AS IDENTITY instead of SERIAL. Postgres 10+ only.

columnName: string

The name of the column.

If no value is provided, Sequelize will use the name of the attribute (in snake_case if InitOptions.underscored is true)

comment?: string

Comment to add on the column in the database.

defaultValue?: unknown

A literal default value, a JavaScript function, or an SQL function (using fn)

field?: string


use columnName instead.

fieldName: string
get?: ((this) => unknown)

Provide a custom getter for this column. Use Model.getDataValue to access the underlying values.

Type declaration

    • (this): unknown
    • Parameters

      • this: M

      Returns unknown

What should happen when the referenced key is deleted. One of CASCADE, RESTRICT, SET DEFAULT, SET NULL or NO ACTION

What should happen when the referenced key is updated. One of CASCADE, RESTRICT, SET DEFAULT, SET NULL or NO ACTION

primaryKey?: boolean

If true, this attribute will be marked as primary key

set?: ((this, val) => void)

Provide a custom setter for this column. Use Model.setDataValue to access the underlying values.

Type declaration

    • (this, val): void
    • Parameters

      • this: M
      • val: any

      Returns void

Like AttributeOptions.type, but normalized.

An object of validations to execute for this column every time the model is saved. Can be either the name of a validation provided by validator.js, a validation function provided by extending validator.js (see the DAOValidator property for more details), or a custom validation function. Custom validation functions are called with the value of the field, and can possibly take a second callback argument, to signal that they are asynchronous. If the validator is sync, it should throw in the case of a failed validation, it is async, the callback should be called with the error text.
