Question

我有一个模型MyQuiz，它通过问题属于测验，也属于用户

在模型上创建测验：测验和问题。因此模型MyQuiz是记录答案的模型

我使用的是SimpleForm，所以我想出了MyQuiz的这个表格

  = simple_form_for(@my_quiz) do |f|
    = f.error_notification

    - @questions.each do |question|
      .form-group
        %p= question.title
        = f.input :answer, as: :radio_buttons
        = f.input :question_id, as: :hidden, :input_html => { :value => question.id }
        = f.input :user_id, as: :hidden, :input_html => { :value => current_user.id }
    .form-group
      = f.button :submit, class: "btn btn-primary pull-right"

my_quizzes_controller.rb

def new
  @quiz = Quiz.find(params[:quiz_id])
  @questions = @quiz.questions.all
  @my_quiz = MyQuiz.new
end

def create
  @my_quiz = MyQuiz.new(my_quiz_params)
  if @my_quiz.save
    redirect_to user_path(@user), notice: "Thank you taking the quiz!"
  else
    render "new"
  end
end

private

def my_quiz_params
  params.require(:my_quiz).permit(:question_id, :user_id, :answer)
end

此表单的问题在于未正确设置序列化答案。所以它就好像所有答案都是一样的。甚至单选按钮的行为方式也相同

我不太确定我应该在这做什么。我也尝试过使用simple_fields_for的hacky解决方案，但它没有改变结果。

提前致谢

更新：使用建议和另一次尝试

所以建议将MyQuiz表格作为嵌套表格

类似的东西：

    = simple_form_for @user do |g|
      = g.error_notification
      - g.simple_fields_for @my_quiz do |f|
        - @questions.each do |question|
          .form-group
            %p= question.title
            = f.input :answer, as: :radio_buttons
            = f.input :question_id, as: :hidden, :input_html => { :value => question.id }
            = f.input :user_id, as: :hidden, :input_html => { :value => current_user.id }
      .form-group
        = g.button :submit, class: "btn btn-primary pull-right"

我尝试过但仍然遇到与单选按钮相同的问题。
我认为这可能是对UserModel创建/更新的不必要的调用。

我一直在玩这样的选项：

  = form_tag my_quizzes_path do
    - @questions.each do |question|
      %p= question.title
      = radio_button_tag "my_quizzes[#{question}][answer]", '0'
      = radio_button_tag "my_quizzes[#{question}][answer]", '1'
      = hidden_field_tag "my_quizzes[][question_id]"
      = hidden_field_tag "my_quizzes[][user_id]"

  = submit_tag "Submit"
