Properties

charset?: string

The charset to use for the model

collate?: string

The collation for model's table

comment?: string

A comment for the table.

MySQL, PG only.

createdAt?: string | boolean

Override the name of the createdAt attribute if a string is provided, or disable it if false. ModelOptions.timestamps must be true.

Not affected by underscored setting.

defaultScope?: FindOptions<Attributes<M>>

Define the default search scope to use for this model. Scopes have the same form as the options passed to find / findAll.

deletedAt?: string | boolean

Override the name of the deletedAt attribute if a string is provided, or disable it if false. ModelOptions.timestamps must be true. ModelOptions.paranoid must be true.

Not affected by underscored setting.

engine?: string

The name of the database storage engine to use (e.g. MyISAM, InnoDB).

MySQL, MariaDB only.

freezeTableName?: boolean

If true, sequelize will use the name of the Model as-is as the name of the SQL table. If false, the name of the table will be pluralised (and snake_cased if ModelOptions.underscored is true).

This option has no effect if ModelOptions.tableName is set.

default

false

getterMethods?: ModelGetterOptions<M>

Allows defining additional getters that will be available on model instances.

hasTrigger?: boolean

Indicates if the model's table has a trigger associated with it.

default

false

hooks?: { afterBulkCreate?: any; afterBulkDestroy?: any; afterBulkRestore?: any; afterBulkSync?: any; afterBulkUpdate?: any; afterCreate?: any; afterDestroy?: any; afterFind?: any; afterQuery?: any; afterRestore?: any; afterSave?: any; afterSync?: any; afterUpdate?: any; afterUpsert?: any; afterValidate?: any; beforeBulkCreate?: any; beforeBulkDestroy?: any; beforeBulkRestore?: any; beforeBulkSync?: any; beforeBulkUpdate?: any; beforeCount?: any; beforeCreate?: any; beforeDestroy?: any; beforeFind?: any; beforeFindAfterExpandIncludeAll?: any; beforeFindAfterOptions?: any; beforeQuery?: any; beforeRestore?: any; beforeSave?: any; beforeSync?: any; beforeUpdate?: any; beforeUpsert?: any; beforeValidate?: any }

Add hooks to the model. Hooks will be called before and after certain operations.

This can also be done through Model.addHook, or the individual hook methods such as {@link Model.afterQuery}. Each property can either be a function, or an array of functions.

                                                                                                                                      underscored?: boolean

                                                                                                                                      If true, Sequelize will snake_case the name of columns that do not have an explicit value set (using ModelAttributeColumnOptions.field). The name of the table will also be snake_cased, unless ModelOptions.tableName is set, or ModelOptions.freezeTableName is true.

                                                                                                                                      default

                                                                                                                                      updatedAt?: string | boolean

                                                                                                                                      Override the name of the updatedAt attribute if a string is provided, or disable it if false. ModelOptions.timestamps must be true.

                                                                                                                                      Not affected by underscored setting.

                                                                                                                                      An object of model wide validations. Validations have access to all model values via this. If the validator function takes an argument, it is assumed to be async, and is called with a callback that accepts an optional error.

                                                                                                                                      version?: string | boolean

When enabled, sequelize will add a version count attribute to the model and throw an OptimisticLockingError error when stale instances are saved.

                                                                                                                                      • If string: Uses the named attribute.
