Components going out of style?

David, I understand that components are going out, but I still think
they result in cleaner code than what you're proposing here and clean
and easy to understand code is what rails is all about isn't it?

For example I personally find:

1. Extracting the set_cart out and then mixing it in to all controllers
that need it, calling it via a before_filter, and then rendering a
partial in all views that need it

It isn't complex to use the filters...

def ApplicationController
  private
    def set_cart
      @cart =
    end
end

def CartController < ApplicationController
  before_filter :set_cart :only=>[:show]

  def show
  end
end

def CheckoutController < ApplicationController
  before_filter :set_cart :only=>[:confirm_order]

  def confirm_order
  end
end
