为什么铁路日期比较没有发挥作用?
原标题:Why is Rails date comparison not working?

我在这里所缺的是,它使我cra。

>> user.current_login_at.utc > 24.hours.ago.utc
=> false
>> 24.hours.ago.utc
=> Mon May 17 18:46:16 UTC 2010
>> user.current_login_at.utc
=> Mon May 17 15:47:44 UTC 2010

用户:目前是27小时前,但比比较多的是24小时前。 这使我感到欣慰。

最佳回答

日期“大于”是指“之后”。 。 从概念上讲,你正在要求“在24小时前的这段时间过后复制用户标识吗?” 而不是“在24小时多前复制用户记录? 因此,你想要:

user.current_login_at.utc < 24.hours.ago.utc

什么话说“在24小时前向用户记录?”

问题回答

你们正在使用“比”的“比”一词,后者在目前比较中意味着“比”的“次要”。

目前的标识是否晚于24小时?

user.current_login_at.utc > 24.hours.ago.utc

目前的标识早于24小时?

user.current_login_at.utc < 24.hours.ago.utc
