Rails - Sep 2006 - When do I need to reload?

Hi, in this method update, after sort positions, at the block I haven''t
objetcs! and it''s raised a nil
object error...

  def update
    positions = self.league_positions
    positions.sort
    positions.each do |pos, i|
      pos.position = i + 1 <---------------- pos doesn''t exists
      pos.save
    end
    self.save
  end

How could I resolve this?, Do I need to reload?, Which is the criteria
I have to follow to reload objects?

Sorry, I had some mistakes, but the once fixed I have the same results:

  def update
    positions = self.league_positions
    ordered_positions = positions.sort
    i = 1
    ordered_positions.each do |pos|
      pos.position = i
      i = i.next
      pos.save
    end
    self.save
  end

I think today I have to be quiet :)... not a good day. I have several
mistakes, one of them was to
name the method ''update'', what a mistake!!! it made infinite
loop!!

Now it works...

  def update_positions
    positions = self.league_positions
    ordered_positions = positions.sort
    i = 1
    ordered_positions.each do |pos|
      pos.position = i
      i = i.next
      pos.save
    end
    self.save
  end
