So, with nested_attributes, you're not supposed to iterate over anything at all - f.fields_for :answer_singles will iterate over all the report's AnswerSingle object and yield to the block once for each one. With this way of thinking if you want one AnswerSingle for each QuestionSingle then you'd want to do something like this in your controller QuestionSingle.each do |qs| report.answer_singles.build ... end passing to build whatever attributes need to be set on the answer_single to link it to the question single it corresponds to.
