Rails - Jul 2006 - workweek_select

I''m having difficulty figuring out the ruby neccessary to do this so I
thought I would try the list. I''m hoping to get a date_select to only
display certain days (specifically only fridays) but rails doesn''t
seem to have the flexibility so I''ve been going at it in ruby to no
avail.

I''ve looked on google but couldn''t find it (because it
isn''t there or
I don''t know exactly what to search for). I''m not concerned
about
having the full railsy date select but it would be nice if it''s
possible.

This is the code so far:

  def select_friday(in_model, in_attr)
    # Scope breaker
    friday = ""

    # This seems to never trigger at all. A breakpoint before the
conditional is never honored.
    Date.today.step(7, 1) do |day|
      if day.wday == 5
        friday = day
      end
    end

    @dates = []
    friday.step(20, -7){|day| @dates << day}
    friday.step(20, 7){|day| @dates << day}
    @dates.sort!

    select in_model, in_attr, @dates
  end

Thanks for any suggestions.

Cheers,
Chuck Vose

This will get the next friday, including today if it is a friday:

  def get_next_weekday(weekday)
    date = Date.today
    until date.wday == weekday
      date += 1
    end
    date
  end

Then you can do:

  def select_friday(in_model, in_attr)
    friday = get_next_weekday(5)

    @dates = []
    friday.step(20, -7){|day| @dates << day}
    friday.step(20, 7){|day| @dates << day}
    @dates.sort!

    select in_model, in_attr, @dates
  end

And to display them, you should be able to use the standard (non date 
specific) select tag:

  <%= select ''model'', ''date_field'',
      @dates.collect {|date| [date.to_s(:short), date.to_s(:db)] } %>

The value of each friday on the list is "2006-07-21", ready to be sent
to the DB, but the user sees "Jul 21, 2006" or whatever format is 
assigned to the :short symbol.

That''s an error, it should say that it will get the next specified 
weekday, obviously.
