在我看来,我想以“mm / dd / yyyy”格式显示当前日期。
<%= Time.now.strftime("%m/%d/%Y") %>
You could simply do (substitute in Time
for DateTime
if using straight Ruby -- ie no Rails):
DateTime.now.strftime('%m/%d/%Y')
If you're using that format a lot, you might want to create a date_time_formats
initializer in your RAILS_ROOT/config/initializers
folder (assuming Rails 2), something like this:
# File: date_time_formats.rb
ActiveSupport::CoreExtensions::Time::Conversions::DATE_FORMATS.merge!(
:human => "%m/%d/%Y"
)
Which will then let you use the more friendly version of DateTime.now.to_s(:human)
in your code.
I think you can use .strftime
:
t = Time.now()
t.strftime("The date is %m/%d/%y")
This should give "The date is 09/09/10"
. See here for a great list of the format codes for .strftime
.
如果您不需要全年,可以尝试Time.now.strftime('%D')
