Question

我尝试设置我的rails应用，以便当用户访问www.example.com/personal_messages/new时，它不会创建新帐户，而是在用户提交时。但问题是，如果移动User.create函数，我将收到错误。有解决方法吗？

personal_messages controller

class PersonalMessagesController < ApplicationController
  before_action :check_receiver!, only: [:new, :create]

  def new
    redirect_to conversation_path(@conversation) and return if @conversation
    @personal_message = current_user.personal_messages.build
  end

  def create
    @conversation ||= Conversation.create(author_id: cookies[:user_id],
                                         receiver_id: @receiver)
    @personal_message = current_user.personal_messages.build(personal_message_params)
    @personal_message.conversation_id = @conversation.id
    @personal_message.save!

    flash[:success] = "ok!"
    redirect_to conversation_path(@conversation)
  end

  private

  def personal_message_params
    params.require(:personal_message).permit(:body)
  end

  def check_receiver!
    @ip = request.remote_ip
    if cookies[:user_id].blank?
     @user = User.create(email: "thinkrtcvisitor-#{rand(999999)}@visitor.com", ip_address: @ip, password: '12345678', password_confirmation: '12345678')
       @user.save!
        cookies.permanent[:user_id] = @user.id
        cookies.permanent[:current_user_cookie] = User.find_by_id(cookies[:user_id])
        session[:user_id] = @user.id
   end
    @receiver = cookies[:site_id]
    @conversation = Conversation.between(cookies[:user_id], @receiver)[0]
  end
end

使用

@personal_message = current_user.personal_messages.new

而不是

@personal_message = current_user.personal_messages.build

在new行动中。
