Question

这是错误消息及其应用程序跟踪：

NoMethodError in Shopping::OrdersController#index

(the root of error is the application directory.)
undefined method `completed_at' for 2012-08-03 20:24:48 UTC:Time

app/models/coupon.rb:44:in `eligible?'
app/models/coupon.rb:40:in `qualified?'
app/models/coupon.rb:34:in `value'
app/models/order.rb:276:in `coupon_amount'
app/models/order.rb:260:in `find_total'
app/models/order.rb:284:in `credited_total'
app/controllers/shopping/orders_controller.rb:100:in `form_info'
app/controllers/shopping/orders_controller.rb:21:in `index'

但是，当我选择查看完整跟踪时，第一行是

activesupport (3.2.7) lib/active_support/time_with_zone.rb:328:in `method_missing'

我不确定这是控制器的问题还是active_support的问题。有人知道怎么修这个东西吗？谢谢！

在coupon.rb

def qualified?(item_prices, order, at = nil)
  at ||= order.completed_at || Time.zone.now
  item_prices.sum > minimum_value && eligible?(at)
end

def eligible?(order, at = nil)
  at ||= order.completed_at || Time.zone.now
  starts_at <= at && expires_at >= at
end

感谢。

在coupon.rb的第44行，您正在completed_at对象上调用Time。我不知道你的代码是哪一行，但这应该足以让你完成。

未定义方法`completed_at'for 2012-08-03 20:24:48 UTC：时间
