Mongoose Discriminators

To add discriminators to a model, you may specify a discriminators array in the long-form options shown above.

You may either add just the class, or if you need to override the discriminator key value, an object with typegooseClass and discriminatorId property.

For example:

class Tabby extends Cat {
  @prop()
  spotted: boolean 
}

class BlackCat extends Cat {
  @prop()
  unlucky: boolean
}

@Module({
  imports: [
    TypegooseModule.forFeature([
      {
        typegooseClass: Cat,
        discriminators: [
          Tabby,
          {
            typegooseClass: BlackCat,
            discriminatorId: 'Black'
          }
        ]
      }
    ])
  ]
})
export class CatsModule {}
