验证失败：作业无效（Ruby on Rails）

Question

我一直在YouTube上观看此系列影片，但是现在我每次尝试发布时都会遇到此错误。

Rails可以解决此问题吗？

这是错误消息：

验证失败：作业无效 创建 app / controllers / jobs_controller.rb，第54行

这是我的jobs_controller.rb：

class JobsController < ApplicationController
  before_action :set_job, only: [:show, :edit, :update, :destroy]
  before_action :authenticate_user!, except: [:index, :show]

  # GET /jobs
  # GET /jobs.json
  def index
    @jobs = Job.all.order("created_at desc")
  end

  # GET /jobs/1
  # GET /jobs/1.json

  end

  # GET /jobs/new
  def new
    @job = current_user.jobs.build

  # GET /jobs/1/edit
  def edit
  end

      current_user.card_exp_month = card_exp_month
      current_user.card_exp_year = card_exp_year
      current_user.card_last4 = card_last4
      current_user.save!

    respond_to do |format|
      if @job.save

    # Never trust parameters from the scary internet, only allow the white list through.

您对current_user.save!的呼叫在您有机会尝试保存作业之前引发错误。尝试将current_user.save!临时更改为current_user.save，然后将错误信息添加到闪存中：flash.alert = @job.errrors.full_messages.join(', ')）

  # POST /jobs
  # POST /jobs.json
  def create
    @job = current_user.jobs.build(job_params)

    token = params[:stripeToken]
    job_type = params[:job_type]
    job_title = params[:title]
    card_brand = params[:user][:card_brand]
    card_exp_month = params[:user][:card_exp_month]
    card_exp_year = params[:user][:card_exp_year]
    card_last4 = params[:user][:card_last4]

    charge = Stripe::Charge.create(
      :amount => 30000,
      :currency => "usd",
      :description => job_type,
      :statement_descriptor => job_title,
      :source => token
      )

      current_user.stripe_id = charge.id
      current_user.card_brand = card_brand
      current_user.card_exp_month = card_exp_month
      current_user.card_exp_year = card_exp_year
      current_user.card_last4 = card_last4
      current_user.save

    respond_to do |format|
      if @job.save
        format.html { redirect_to @job, notice: 'Your job listing was purchased successfully!' }
        format.json { render :show, status: :created, location: @job }
      else
        flash.alert = @job.errrors.full_messages.join(', ')
        format.html { render :new }
        format.json { render json: @job.errors, status: :unprocessable_entity }
      end
    end
  end
