我有一个订单表格，它接受表格中的信用卡信息。它似乎无法正常工作，因为每次我输入测试信息并提交它只会让我回到新的操作，这意味着@order.save它不起作用。我不明白为什么我的订单没有保存。

这是服务器日志：

订单模型

应用控制器

 def current_cart
    if session[:cart_id]
          @current_cart ||= Cart.find(session[:cart_id])
          session[:cart_id] = nil if @current_cart.purchased_at
    end
    if session[:cart_id].nil?
      @current_cart = Cart.create!
      session[:cart_id] = @current_cart.id
    end
    @current_cart
  end

非常感谢任何见解。

三种调试方法：

1) 从重定向更改为渲染。这将保持相同的 @order 对象并可能显示视图中的错误：

if @order.save
  #...          
else
  render :new
end

2）如果无法保存，请告诉rails到rails一个异常。

if @order.save!

当您已经render :new无法找出错误是什么时，这很有用。

3）添加一些日志：

if @order.save
  #...
else
  logger.debug @order.errors.full_messages.join(", ")
  render :new
end
