Ruby on rails 未知属性'；回答了"问题"和"属性"x27；

我试图创建一个表单，用户可以在其中回答问题并提交到结果页面，但是，当我试图通过测验控制器传递AnsweredQuestions属性时，它告诉我这是一个“未知属性”

我收到错误：AnsweredQuestion的未知属性“已回答的问题”属性

quick.rb：

 class Quiz < ApplicationRecord
  validates :title, presence: true, length: { maximum: 50 }
  has_many :questions, dependent: :destroy
  has_many :answered_questions, through: :questions, dependent: :destroy
  accepts_nested_attributes_for :answered_questions, reject_if: :all_blank, allow_destroy: true
  accepts_nested_attributes_for :questions, reject_if: :all_blank, allow_destroy: true
end

show.html.erb（在测验中）：

@quick.id%>
问题%id>
@quick.id%>

更新：

show.html.erb（测验）：

@quick.id%>
问题%id>
@quick.id%>

回答问题控制员：

  def show
    @quiz = Quiz.find(params[:id])
    @questions = Question.all
    @answered_questions = current_user.answered_questions.build

    @quiz.answered_questions.build

  end

  def create 
    @quiz = Quiz.new(show_params)
    if @quiz.save
      flash[:success] = "You have created a new quiz!"
      redirect_to @quiz
    else 
      render 'new'
    end
  end


  def post_answered_questions 
    @answered_question = current_user.answered_questions.build(show_params)
    if @answered_question.save
      flash[:success] = "You have completed the quiz!"
      redirect_to results_quiz_path(params[:quiz][:id])
    else
      render ''
    end
  end

  private

  def user_completed_quiz 
    if(current_user.answered_questions.pluck(:quiz_id).uniq.include?(params[:id].to_i)) 
      redirect_to quizzes_path
    end
  end

  def show_params
    params.require(:quiz).permit(:title, answered_questions_attributes: [:id, :answer_id, :question_id, :user_id, :quiz_id], questions_attributes: [:id, :question_title, :quiz_id, :done, :_destroy, answers_attributes: [:id, :answer_title, :question_id, :quiz_id, :correct_answer, :_destroy]])
  end
end

class AnsweredQuestionsController < ApplicationController


  def show
    @answered_question = AnsweredQuestion.new
  end

  def create
    @answered_question = current_user.answered_questions.build(answered_params)
    binding.pry
    if @answered_question.save
      flash[:success] = "You have completed the quiz!"
      redirect_to results_quiz_path(params[:quiz][:id])
    else
      render ''
    end
  end

  def edit
    @answered_questions = AnsweredQuestion.find(params[:id])
  end


  def destroy
    AnsweredQuestion.find(params[:id]).destroy
    flash[:success] = "Answered quiz deleted"
    redirect_to answered_questions_url
  end

  private


  def answered_params
    params.require(:answered_questions).permit(:question_id, :answer_ids, :user_id, :quiz_id, :id, :_destroy)
  end

end

类回答问题控制器

看起来您正在接受

测验的嵌套属性，但使用
回答问题
中的嵌套属性，而不是
测验
中的嵌套属性。您需要在另一个模型中添加
接受
的

嵌套属性，并在

显示参数

中，它应该是

测验属性

，而不是

回答的问题属性

。尽管您使用了两次

show_params

，一次用于一个模型，另一次用于另一个模型，因此您可能需要两个参数。否则你会打断另一个。

我也用表格更新了原始问题，不知道你的意思是什么？我只是尝试在测验控制器

当前用户中传递回答的问题参数。回答的问题。生成（显示参数）

我尝试改变它，使其用于测验而不是回答的问题，但它仍然不起作用。为什么您试图通过

测验
为回答的问题保存记录？这种逻辑应该放在它自己的控制器中。此外，关系设置不正确，
测验
有许多
问题
有许多
问题回答
，因此
问题回答
不应直接属于
测验
，这导致了非规范化。我最初将其放在它自己的控制器中，但当我这样做时，它会说“已回答的问题”参数为空，我已更新帖子以反映它的外观，现在我已将其放在它自己的控制器中，我没有看到任何错误。。。您能否将调用
answered_params
方法的结果发布到创建操作中？
