Rails - Aug 2006 - Use collection_select

I use the following code in my view:

<%= collection_select(''datedata'', ''date'',
@allDate, :id, :date) %>

It''s show me the date of all entries in the database (Dropdown menu). 
Additional, I wrote a helper method "showDate" in the 
application_helper.rb! How can I use this method in the 
collection_select for every date entry?

thanks for your anwser!

What is it that you''re trying to accomplish with your
''showDate'' method?

I would like to show the date in my favorite style. The following code 
is the used method:

def showDate(d)
  d.strftime("%d.%m.%y")
end

I want to display the date in the collection with the method!

The first idea that comes to mind is to modify your collection_select call:
<%= collection_select(''datedata'', ''date'',
@allDate.collect{|d| showDate(d)},
:id, :date) %>

But that''s a little ugly.  You could modify your helper thusly:
def showDate(d=Time.now)
  date_format = "%d.%m.%y"
  if Array === d
    d.collect {|date| date.strftime(date_format)}
  else
    d.strftime(date_format)
  end
end

This lets you pass the helper a Date object or an array of Dates, and get
back what you''d expect.
