#reform

If you use Reform for the form objects and want the translations in your Rails application to work as with ActiveRecord objects, then you can add ActiveModel::Translation module to the form class or base class and specify the method with the key to translations.

 class BaseForm < Reform::Form extend ActiveModel::Translation def self.i18n_scope :forms end end 

 class UserForm < BaseForm feature Coercion property :login property :change_password, virtual: true, type: Types::Form::Bool property :password property :password_confirmation validation do required(:login).filled end validation if: ->(_) { change_password } do required(:password).confirmation end end 

Set translations for form fields.

You can move them to a new file config/locales/forms.yml.

 en: forms: attributes: user_form: login: Enter login change_password: Change password? password: Enter password password_confirmation: Confirm password 

Now, translations will be used by the simple form or you can call them manually by UserForm.human_attribute_name.
