Question

我有一个Rails应用程序，可以从手机上加载图片。该模型是钞票，并且有图片。

当我点击“提交”按钮以创建带有其图片的账单时，在生产中出现此错误：

保存帐单时，我试图挽救控制器中的错误：

  def create
    bill = Bill.new(bill_params)
    customer_id = params[:customer_id]
    @customer = Customer.find(customer_id)
    bill.customer = @customer
    bill.datum = Date.today if params[:bill][:datum].empty?

    begin
      bill.save
    rescue RuntimeError => e
        print_exception(e, true)
        puts "albert errorrrr"
    end

    redirect_to customer_path(@customer)
  end

但也不起作用。我检查了文档，我认为救援应该像这样编写。救援代码正确吗？还是我错过了什么？

预先感谢
