Constructor Details

#initialize(mapper, composition) ⇒ Form

reasons for delegation: presentation: this object is used in the presentation layer by #form_for. problem: #form_for uses respond_to?(:email_before_type_cast) which goes to an internal hash in the actual record. validation: this object also contains the validation rules itself, should be separated. TODO: figure out #to_key issues.
