Question

我不确切知道这个问题的正确标题是什么，抱歉。

我有一个Question模型，用户应该输入5个问题，然后在问题表中提交。

问题是它只提交一个问题，这是最后一个问题。

如何让它同时提交所有问题字段？

的观点：

<% question_numbering = 0 %>

<%= simple_form_for(@quiz, html: {class: 'form-vertical' }) do |f| %>
    <%= render 'shared/error_messages_question' %>

    <div>
        <%=  %>
        question <%= question_numbering += 1 %><br>
        <%= f.input_field :content, :rows => 3, :style => "width:80%", :placeholder => "enter your question."  %><br>
        question <%= question_numbering += 1 %><br>
        <%= f.input_field :content, :rows => 3, :style => "width:80%", :placeholder => "enter your question."  %><br>
        question <%= question_numbering += 1 %><br>
        <%= f.input_field :content, :rows => 3, :style => "width:80%", :placeholder => "enter your question."  %><br>
        question <%= question_numbering += 1 %><br>
        <%= f.input_field :content, :rows => 3, :style => "width:80%", :placeholder => "enter your question."  %><br>
        question <%= question_numbering += 1 %><br>
        <%= f.input_field :content, :rows => 3, :style => "width:80%", :placeholder => "enter your question."  %><br>
    </div>
    <%= f.submit 'Submit', :class => "btn btn-default" %>
<% end %>

控制器：

class QuestionsController < ApplicationController
  def index
    @quiz = Question.new
    @questioner = Questioner.new
  end

  def new
    @quiz = Question.new(quiz_params)
  end

  def show
    @quiz = Question.find(params[:id])
  end

  def edit
    @quiz = find(params[:id])
    raise "Question Not edited!" unless @quiz
  end

  def create
    @quiz = Question.new(quiz_params)

    if @quiz.save
      flash[:warning] = 'You have successfully posted the questions!'
      redirect_to questions_path
    else
      flash[:error] = "Please review the problems below."
      # render 'new'
      redirect_to questions_path
    end
  end

  private

    def quiz_params
      params.require(:question).permit(:content, :answered, :questioner_id, :category_id)
    end
end

您目前正在使用问题资源 - 一次创建一个问题才真正有意义，因为它们不作为集合存在，而是作为单独的单元存在。

如果您有其他资源，例如Quiz，它有很多问题 - 那么一次创建多个问题是有意义的。

您需要将测验创建为与问题有has_many关联的单独资源。
