我不得不把“地铁:%M”指在我的铁路项目中显示时间的任何东西。 我每个音乐家都有起步的时间和结束时间,因此,每当I wanna展示时,我必须附上“水平”(“%H:%M”)。
请注意,我不要求改变日期格式。 日期是罚款(作为MM/DD/YYYYYY)。
What s the best way to get around this? Is there a way to set the default time format?
(我确信这只是一回事,但我是一把新东西,因此我不相信。)

铁路局的R.R.R.R.C.R.R.R.R.R.R.R.R.R.R.R.R.R.R.R.R.R.R.R.R.R.R.R.R.R.R.R.R.R.R.R.R.R.R.R.R.R.R.R.R.R.R.R.R.R.R.R.R.R.R.R.R.R.R.R.R.R.R.R.R.R.R.R.R.R.R.R.R.R.R.R.R.R.R.R.R.R.R.R.R.R.R.M.R.R.R.R.R.R.R.R.R.R.R.R.R.R.R.R.R.R.R.R.R.R.R.R.R.R.R.R.R.R.R.R.R.R.R.R.R.R. 在我机器上的<条码>时条码>:
>> Time::DATE_FORMATS
=> {:short=>"%d %b %H:%M", :db=>"%Y-%m-%d %H:%M:%S", :rfc822=>#<Proc:0x0000000103700b08@/Users/donovan/.gem/gems/activesupport-3.0.1/lib/active_support/core_ext/time/conversions.rb:13>, :time=>"%H:%M", :number=>"%Y%m%d%H%M%S", :long_ordinal=>#<Proc:0x0000000103700e50@/Users/donovan/.gem/gems/activesupport-3.0.1/lib/active_support/core_ext/time/conversions.rb:12>, :long=>"%B %d, %Y %H:%M"}
你们可以轻易地利用他们:
>> Time.now.to_s(:db)
=> "2011-01-12 15:26:11"
You can define your own and use it, too:
>> Time::DATE_FORMATS[:mine] = "%H:%M"
=> "%H:%M"
>> Time.now.to_s(:mine)
=> "15:28"
您可在其申请中建立习惯功能——助手。 也许像:
def custom_time(date)
date.strftime("%H:%M")
end
这不是说这是最好的做法,而是应该做得好。
我使用一个初始器:组合/初始器/时间_formats.rb,其中包括:
[Time, Date].map do |klass|
klass::DATE_FORMATS[:app_date] = "%m/%d/%Y"
klass::DATE_FORMATS[:app_month_and_year] = "%B %Y"
klass::DATE_FORMATS[:app_abbrev_month_and_year] = "%b %Y"
...
end
Then I use Time.now.to_s(:app_date), etc based on how I want to display it.
You could add Time::DATE_FORMATS[:default] = "%H:%M"
to accomplish what you re trying to do. This is not internationalized though - for that, coreyward s answer is probably better.
