I am successfully navigating between controllers. However, I am unable to construct a new child (question) record. What does "undefined method `stringify_keys!'' really mean"? I think I am missing a subtlety of Ruby syntax here, since the question_controller is actually trying to call the Question constructor. Can someone point out what I am missing please? Thanks in advance. question_controller: def new @question = Question.new(params[:parent_quiz]) end question.rb: def new (quiz) quiz = quiz end Application trace: /usr/lib/ru...

...ose rows back to the rails application? The specific example is a screen for editing a question with its list of answers as a sovereign application. Both code snips are from views/question/_form.rhtml. I realize that I do not have the server side of the interface represented from controllers/question_controller.rb. In part, this is because I have a gap in my knowledge about what the HTTP post will provide back to the ruby app - it is presumed to be self evident in the books I have available.
