You could simply do (substitute in Time for DateTime if using straight Ruby -- i.e. no Rails):

你可以做的很简单(如果使用直接的Ruby——即没有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:

如果您经常使用这种格式，您可能希望在RAILS_ROOT/config/initializers文件夹(假设Rails 2)中创建一个date_time_formats初始化器，内容如下:

# 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.

然后让您使用更友好的DateTime.now.to_s(:human)在您的代码中。

I think you can use .strftime:

我想你可以用。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.

这应该给出“日期是09/09/10”。有关.strftime格式代码的大量列表，请参见这里。

If you don't need the full year you could try Time.now.strftime('%D')

如果你不需要一整年的时间，你可以试试Time.now.strftime('%D')
