Question

下午好！

我似乎无法在我的门票上找到问题所在，我想也许再看看它会有所帮助:)。另外，非常感谢您利用时间帮助我。

除了“创建”操作之外，我的故障单的所有页面都能正常工作。在我点击New的Create Ticket后，通过转到tickets_path，重定向甚至可以正常工作。但是，它一直闪烁到无法提交票证。并且不会在表格中创建记录。

但是没有错误，控制台会在下面的日志中显示表单的参数。

# Controller
class TicketsController < ApplicationController
  before_filter :authenticate_user!
  before_action :set_ticket, only: [:show, :edit, :update, :create]

  def index
    @tickets = Ticket.includes(:category, :user, :ticket_status)
    #authorize User
  end

  def show
    @ticket = Ticket.find(params[:id])
    #authorize @user
  end

  def new
    @ticket = Ticket.new
    @ticket.ticket_status = TicketStatus.find_by_name("Open")
  end

  def edit
    @ticket = Ticket.find(params[:id])
  end

  def create
    @ticket = Ticket.new(ticket_params)
    if @ticket.save
      redirect_to tickets_path, :notice => "Ticket Submitted."
    else
      redirect_to tickets_path, :alert => "Unable to submit ticket."
    end
  end

  def update
    @ticket = Ticket.find(params[:id])
    if @ticket.update(ticket_params)
      redirect_to tickets_path, :notice => "Ticket updated."
    else

Answer 1

您在发出POST请求时缺少user_id属性

这是因为这一行：

 <td><%= f.label :user_id, "User Name" %></td>

你打算写

 <td><%= f.hidden_field :user_id, value: current_user.id  %></td>

为什么我的Tickets控制器创建操作失败？
