Rails - Aug 2006 - form parameter

How can I change some parameters in a function of the controller. I have 
a User_Controller, who''s responsible for update the information fields 
in the database.

The parameters are "id", "firstname" and
"lastname". Now, I want to
manipulate parameter "lastname", because I would like to add at the
end
a point.

------>>> Thomas Miller.
until now, I have the following codelines. But it doesn''t manipulate
the
lastname-parameter. Can anyone help to manipulate this parameter?

Example:
--------

def update
  @user = User.find(params[:id])
  if @user.update_attributes(params[:user])
    flash[:notice] = ''User was successfully updated.''
    redirect_to :action => ''show'', :id => @user
  else
    render :action => ''edit''
  end
end

!!! Thanks for your help !!!

Another way, possible nicer, is to do it in the model, along the lines
of:

   class User < AR::Base
     before_save :add_dot
     def add_dot
       self.name += "."
     end
     # ...
   end
