Rails - Apr 2006 - saving controller state

Basically I''m trying to add the following functionality to a controller
when browsng data

reorder data
change numbers of rows
defining filters
etc.

for that, I need to save the state of a controller, that is, the current 
order, the number of rows, the filter condition, etc.

So far now, I''m saving them to the session.

I have a load method, which loads the data from params, or assing 
default values.

Something like this

def load
  @order = session[:order] || ''date desc''
  @order = params[:order] if params[:order]
end

And then I have another method to save the data

def save
  session[:order] = @order
end

The problem is that for every method I have to execute "load" do some 
stuff and then execute "save"

like this

def list
  load
  @resolucion_pages, @resoluciones = paginate :resolucion, :order => 
@order, :per_page => 10
  save
end

Is there some way to automatize this?

I tried with the initialize method, but it seems like the session is not 
available on that method.

Saludos

you could use a before and after filter...
