But here's a coupla ways you might do that. The most direct port is this: these_survey_questions.each do |question_type| clazz = self.class.const_get "SurveyQuestion#{question_type}" q = clazz.new q.store_response response_from_this_user end Another way would be: GreatBigFactoryHash = { "MultiChoice" => SurveyQuestionMultiChoice, "CheckBox" => SurveyQuestionCheckBox, ... } these_survey_questions.each do |question_type| clazz = GreatBigFactoryHash[question_type] q = clazz.new q.store_response response_from_this_user end I'm sure there's a better way, but it's not occurring to me right now.
