<%= Time.now.strftime("%m/%d/%Y") %>

You could simply do (substitute in Timefor DateTimeif using straight Ruby -- i.e. no Rails):
你可以简单地做（替代在Time为DateTime是否采用直板红宝石-即没有Rails的）：
DateTime.now.strftime('%m/%d/%Y')
If you're using that format a lot, you might want to create a date_time_formatsinitializer in your RAILS_ROOT/config/initializersfolder (assuming Rails 2), something like this:
如果你经常使用这种格式，你可能想date_time_formats在你的RAILS_ROOT/config/initializers文件夹中创建一个初始化程序（假设是 Rails 2），如下所示：
# 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.
这将让您DateTime.now.to_s(:human)在代码中使用更友好的版本。

If you don't need the full year you could try
Time.now.strftime('%D')
如果你不需要全年，你可以尝试
Time.now.strftime('%D')
