numericality

Use the numericality validator to clamp a number between two values:

export default class Rating extends Dream {
  public get table() {
    return 'users' as const
  }

  public id: DreamColumn<Rating, 'id'>

  @deco.Validates('numericality', { min: 1, max: 5 })
  public rating: DreamColumn<Rating, 'rating'>
}
