我要走了

ActionController:：未知信息格式

我试图通过一个事务为用户创建多个测验

到目前为止我一直在尝试的。我做得对吗

quick.rb

  def save_to_multiple_users(user_ids)
    transaction do
      user_ids.each do |user_id|
        new_quiz = self.dup
        new_quiz.user_id = user_id
        new_quiz.save!
      end
      return true
    end
    rescue ActiveRecord::RecordInvalid, ActiveRecord::RecordNotSaved => exception
      errors.add :base, exception.message + "for one or more quizzes"
      return false
  end

测验(u controller.rb)

  # POST /admin/quizzes
  # POST /admin/quizzes.json
  def create
    quiz_params = quiz_create_params
    quiz_params.delete(:user_ids)
    @quiz = Quiz.new(quiz_params)
    respond_to do |format|
      if @quiz.save_to_multiple_users(quiz_create_params[:user_ids])
        format.html { redirect_to edit_admin_quiz_path(@quiz), notice: 'Quiz was successfully created.' }
        format.json { render :show, status: :created, location: @quiz }
      else
        format.html { render :new }
        format.json { render json: @quiz.errors, status: :unprocessable_entity }
      end
    end
  end

问题似乎出在你请求的格式上。您使用

respond\u to

，只处理html和json格式。您对该格式的请求是否失败

如果您的请求是通过ajax进行的，那么您还应该处理

format.js

更新

从更新的日志中，url的结尾有一个

.1

，Rails认为这是一种格式，如.json或.html。检查表单的操作url。

您可以发布完整的错误日志吗？@Pavan我已经编辑了错误日志，谢谢您的回复。您可以在提交表单时发布服务器日志吗？@Pavan我发布了服务器日志，希望对hahaHi Lazarus有所帮助！谢谢你的回答，我的请求是一个普通的html post请求，表单是由rails表单生成的
