Using form models (aka decorators) with Devise
To use a form model with devise, you can simply override #resource_class in a controller. A typical use case would be the registrations controller, as users will need some fields only on sign-up. Example:
class Frontend::Authentication::RegistrationsController < Devise::RegistrationsController
private
def resource_class
FrontendUser::AsSignUp # my decorator class, extending from FrontendUser
end
end
