Use collection_select

Rails
1

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.
