how to layout a form for my quiz app and where to post to?

I guess my problem is two-fold:

  1. Right now I'm just displaying the question and answer, but giving the user no option to select his or her choice (the correct answer part were just to test that I can correctly set which answers are correct). I have nested models of Survey > Question > Answer

surveys/show.html.erb:

<ol>
  <% @survey.questions.each do |question| %>
  <li class = 'question'><%= question.content  %>
  <ul>
    <% for answer in question.answers %>

    <li class = 'answer'>
    <%= answer.content %>
    <%if answer.correct_answer == true %>
    <span> <b>Correct Answer</b> </span>
    <% else %>
    <span> <b>Incorrect Answer</b></span>
    <% end%>
    </li>

    <% end %>
  </ul>
  </li>
    <% end %>
</ol>

What would the form equivalent look like?

  1. I can't decide on what action I should POST to. I would typically just submit to the create action in the same controller, but right now I'm using that action to create the survey. Do I just add another controller to post to or should I just add another action in the same controller and treat that as a sort of create action?

Basically, I'd have a QuestionsController and AnswersController this is because I know there may be other things I want to do with a question and answer via HTTP later. I'd also have a table for storing the answer, question and user, which you could call answered_questions

class AnsweredQuestion
  belongs_to :user
  belongs_to :question
  belongs_to :answer
end

class User
  has_many :answered_questions
end

class Question
  has_many :answered_questions
end

class Answer
  has_many :answered_questions
end

class Survey
  has_many :questions
  has_many :answered_questions, through: :questions
  accepts_nested_attributes_for :answered_questions
end

class SurveysController

  def answer_question
   @survey = Survey.find(params[:id])
   @survey.update(answer_question_params) # not sure this is best way here, need to research a better way to create the nested resources rather than update
  end

  private
    def answer_question_params
      params.require(:survey).permit(answered_questions_attributes: [:answer_id, :question_id, :user_id])
    end
end

Then to allow your user select an answer, I'd have something like:

<ol>
  <%= form_for @survey, url: survey_answer_questions_path do |f| %>
  <% @survey.questions.each do |question| %>
  <li class = 'question'><%= question.content  %>
  <ul>
     <%= f.fields_for :answered_questions do |aq| %>
       <%= aq.hidden_field :question, question.id %>
       <%= aq.hidden_field :user, current_user.id %>
       <% question.answers.each do |answer| %>
         <%= aq.radio_button :answer, answer.id, answer.correct_answer %>
         <%= aq.label :answer, answer.content %>
       <% end %>
    <% end %>
  </ul>
  </li>
     <%= f.submit_button "Answer" %>
    <% end %>
</ol>

I'm doing this on the fly, couldn't really test if these are all correct, but it shows a general overview/approach I would take.

Let me know if that helps.
