Function HasMany

Model field decorator factory. Using this decorator, Models can be enriched with one-to-many associations to other Models. The value for the typeFactory argument has to be another Model. By applying this decorator, the decorated field will (depending on the transient argument value) be taken into account when serializing or treemapping the Model containing the decorated field.

Example

Model with a one-to-many association:

import { HasMany, Model } from '@sgrud/data';
import { OwnedModel } from './owned-model';

export class ExampleModel extends Model<ExampleModel> {

  ⁠@HasMany(() => OwnedModel)
  public field?: OwnedModel[];

  protected [Symbol.toStringTag]: string = 'ExampleModel';

}
Copy
