我在我的rails应用程序上做了一个包更新，现在我收到了以下错误
NoMethodError (undefined method `year' for "%m/%d/%Y %H:%M":String):
app/controllers/onload_wips_controller.rb:44:in `parse_times_to_local_format'
以下是parse_times_to_local_format方法
def parse_times_to_local_format
shifts = Delay.get_shifts(@default[:scope])
if (@default[:start_time].size < 11)
@default[:start_time] = @default[:start_time]+' '+shifts.first
end
if (@default[:end_time].size < 11)
@default[:end_time] = @default[:end_time]+' '+shifts.first
end
@default[:start_time] = Time.zone.parse(@default[:start_time],"%m/%d/%Y %H:%M")
@default[:end_time] = Time.zone.parse(@default[:end_time],"%m/%d/%Y %H:%M")
end
不知道该怎么做，以下是我的捆绑秀：

更新
这似乎是一个错误，在rails控制台上执行：
1.9.3-p392 :001 > date = Time.zone.parse("02/02/14 06:00","%m/%d/%Y %H:%M")
给我同样的错误：
NoMethodError: undefined method `year' for "%m/%d/%Y %H:%M":String
from /home/warch/.rvm/gems/ruby-1.9.3-p392/gems/activesupport-3.2.17/lib/active_support/values/time_zone.rb:275:in `parse'
答案 0 :(得分：1)
我认为你想使用方法.strptime：
> DateTime.strptime("01/01/2001 19:00","%m/%d/%Y %H:%M")
=> Mon, 01 Jan 2001 19:00:00 +0000
在你的情况下：
@default[:start_time] = DateTime.strptime(@default[:start_time], "%m/%d/%Y %H:%M")
@default[:end_time] = DateTime.strptime(@default[:end_time], "%m/%d/%Y %H:%M")
