Rails - Jul 2008 - How does Rails implement filters?

Hi,

I got to thinking this morning about filters and how they are actually
implemented.  If I was gonna implement it, I''d be tempted to do
something like this:


class Base

  def perform_action
    action_name
    if self.class.responds_to?(action_name)
      run_before_filters
      run_around_filters { send(action_name) }
      run_after_filters
    else
      # do other things
    end
  end

end


Now I see something like that in action_controller/base.rb, but I see
no mention of filters.  It just calls send(action_name).  Where do the
filters come in?

Thanks,
Ryan

Look in filters.rb
It aliases perform_action
