Rails 3 时区错误 [英] Rails 3 Timezone error

问题描述

我正在为 Rails 3 beta 中的时区支持而苦苦挣扎，我想知道这是一个错误还是我做错了什么.他是问题所在:

<前>>Time.zone = 'Madrid' # 现在是 GMT+2=>马德里">c = Comment.new=> #<评论id:nil，标题:"，pub_at:nil>>c.pub_at = Time.zone.parse('10:00:00')=> 2010 年 5 月 31 日星期一 10:00:00 CEST +02:00>c.保存>C=> #<评论 id: 3, title: "", pub_at: "2010-05-31 08:00:00">>c.重新加载=> #<评论 id: 3, title: "", pub_at: "2010-05-31 08:00:00">ruby-1.8.7-p249 > c.pub_at=> 2010 年 5 月 31 日星期一 13:00:00 CEST +02:00

如您所见，pub_at 属性已正确存储在数据库中，但在检索它时会增加 3 小时，我怀疑这是因为它使用的是 GMT-3 中的本地机器时区.

rails 2.3.5 中相同的命令序列可以完美运行.

有什么技巧吗?我应该举报一张罚单吗?

解决方案

如果我没记错的话，所有日期都以 UTC 格式存储到数据库中.

rails 和 console 处理日期的方式不同！

因此您应该尝试通过将时区设置到您的 application.rb 中来在您的应用程序中测试它

config.local_zone = '马德里'

然后打印值！你应该会看到正确的时间.

希望对您有帮助

I am struggling with time zone support in Rails 3 beta and I would like to know if it is a bug or if I am doing something wrong. He is the problem:

> Time.zone = 'Madrid'  # it is GMT+2
 => "Madrid" 
> c = Comment.new
 => #<Comment id: nil, title: "", pub_at: nil>
> c.pub_at = Time.zone.parse('10:00:00')
 => Mon, 31 May 2010 10:00:00 CEST +02:00 
> c.save
> c
 => #<Comment id: 3, title: "", pub_at: "2010-05-31 08:00:00">
> c.reload
 => #<Comment id: 3, title: "", pub_at: "2010-05-31 08:00:00">
ruby-1.8.7-p249 > c.pub_at
 => Mon, 31 May 2010 13:00:00 CEST +02:00 

As you can see, the pub_at attribute is stored correctly in the database but when it is retrieved it adds 3 hours and I suspect that it is because it is using my local machine timezone that is in GMT-3.

The same sequence of commands in rails 2.3.5 works perfectly.

Any toughts? Should I report a ticket?

解决方案

If i remember well, all the date are store into the database as UTC.

And rails and console doesn't handle the dates as the same way !

So you should try to test it within your application by setting the timezone into your application.rb

config.local_zone = 'Madrid'

And then print the value ! You sould see the correct time.

Hope this help
