When a user logs into my site, Devise tries to update the field in the user model current_sign_in_at with the time. But it's producing this error:
当用户登录到我的站点时，设计尝试在用户模型current_sign_in_at中更新该字段。但它产生了这个错误:
NoMethodError: undefined method `getlocal' for Mon, 08 Nov 2010 03:11:01 +0000:DateTime
[GEM_ROOT]/gems/activesupport-3.0.1/lib/active_support/time_with_zone.rb:75
I've found a couple of resources where people have mentioned this problem. There's an issue on Github with no answer. This page has a solution which works in my development environment, because it involves editing /lib/active_support/time_with_zone.rb, but I need a solution that will also work in my production environment on Heroku. Is there a way I can use my edited version of /lib/active_support/time_with_zone.rb on Heroku? Or is there a better way to deal with the problem?
我找到了一些人们提到这个问题的资源。Github上有个问题没有答案。这个页面有一个在我的开发环境中工作的解决方案，因为它涉及编辑/lib/active_support/time_with_zone。rb，但是我需要一个在Heroku的生产环境中也能工作的解决方案。我是否可以使用我的编辑版本/lib/active_support/time_with_zone。rb Heroku吗?还是有更好的方法来解决这个问题?
Here's what I'm using:
这就是我使用:
Rails 3.0.1
ruby 1.9.2p0 (2010-08-18 revision 29036)

irb> Time.now.getlocal

but
但
irb>DateTime.now.getlocal
NoMethodError: undefined method `getlocal' for Mon, 08 Nov 2010 15:05:16 +0200:DateTime
from (irb):17
So, I assume, you need to convert your DateTime object to Time
因此，我假设，您需要将您的DateTime对象转换为时间。

You can use Ruby mixin technique, something like
您可以使用Ruby mixin技术，比如
irb > module DateTimePatch
irb ?> def get_local

I know this question was 2 years ago, but I think I found the clearer explanation about why it behave that way, found on this question. Just for anyone who probably need more explanations like me.
我知道这个问题是两年前的事了，但我认为我找到了更清晰的解释，解释了为什么它会这样，在这个问题上。只是给那些像我一样需要更多解释的人。
