About

Formidable takes care about your forms. You write a class and

  • Get logic out of your views.
  • Get logic out of your controllers (presenter pattern).
  • Validations will work even if the form can’t be mapped directly to the models.
  • You can unit test your forms directly without touching the template layer at all.
  • Validations
  • Coercions

Forms contains quite complex logic which definitely shouldn’t be in your views
