exporting table data as a html file

I have a model named "notice.rb" with a corresponding controller
"notices_controller.rb" and my db table "notices" contains two text
fields - title and body.

I want to save this table data as an html file in a external
directory. Please help me and suggest me ways to do it. NB: This html
file is not the view corresponding to this model but it should be a
different "html file". You can say that its like exporting data in
html format.

Here is my code for the model and controller....

#notices_controller.rb
class NoticesController < ApplicationController
  before_filter :login_required

  def new
  end

  def create
  @notice = Notice.new(params[:notice])
  @notice.save
  flash.now[:notice] = "Notice created successfully"
  render :action => 'show'
  end

  def show
  @notice = Notice.find(:all)
   end
end

#notice.rb
class Notice < ActiveRecord::Base
belongs_to :user

validates_presence_of :title, :body
attr_accessible :title, :body
end
