rails 3 - given XXX.created_at - How to output the 3 digit month + Day

Give a model.created_at

I've been able to use:

<%="开发者_Go百科#{time_ago_in_words(model.created_at)} ago "%>

What is the helper to output something like

• Oct 8
• Sep 23
• Aug 31
• Jul 11

Bonus points, if it outputs like above, but for any records that were created today (not 24hrs ago but today). it shows the time, example:

• 4:31pm
• 1:20pm
• 9:31am
• Oct 8
• Sep 23
• Aug 31
• Jul 11

Thanks

How about a helper method like:

def formated_date(date)
  if date > Time.now.beginning_of_day
    return date.strftime("%l:%M%p")
  end
  date.strftime("%b %d")  
end
