Defined in:
lib/activeform-rails/unpersistent_model.rb,

Overview

UnpersistentModel allows the ActiveForm::Form object to delegate methods to this object with expected results

  • #model_name is used by Form helpers & Rails frequently to define the form namespace

  • #to_key, #to_param, #id should aways return nil as the Form cannot be persisted unless backed by ActiveModel

  • #persisted? should aways return false as the Form cannot be persisted unless backed by ActiveModel
