Subject: rake task organization

in the "connects" task for the following rakefile, how do I tie-in Item 
and Items so that there's minimal code repetition?  For instance, 
currently Item is defined in the connect task for the rakefile, wheras I 
would rather that Item be "imported" either by requiring a module or 
including the Item.rb file, for example.

What's a good approach?



thufir@ARRAKIS:~/rb$ 
thufir@ARRAKIS:~/rb$ cat Item.rb 
require 'rubygems'
require 'active_record'

class Item <  ActiveRecord::Base
end
thufir@ARRAKIS:~/rb$ 
thufir@ARRAKIS:~/rb$ cat Items.rb 
class Items < ActiveRecord::Migration
	def self.up
		create_table :items do |t|
			t.column :title, :string
			t.column :content, :string
			t.column :source, :string
			t.column :url, :string
			t.column :timestamp, :timestamp
			t.column :keyword_id, :integer
			t.column :guid, :string
			t.column :html, :string
		end
        end
        def self.down
                drop_table :items
        end
end

thufir@ARRAKIS:~/rb$ 
thufir@ARRAKIS:~/rb$ cat rakefile.rb 
require 'rubygems'
require 'active_record'
require 'feed_tools'
require 'yaml'


desc "connects to db"
task :connect do
	db = YAML.load_file("database.yml")
	ActiveRecord::Base.establish_connection(
		:adapter  => db["adapter"],
		:host     => db["host"],
		:username => db["username"],
		:password => db["password"],
		:database => db["database"])
	class Item <  ActiveRecord::Base  ###take out this line?
	end
	puts "connected to db"
end


desc "drop table items"
task :drop => :connect do
	#drop table items
	puts "unable to drop table"
end

desc "creates table items unless exists"
task :create => :connect do
	#create table items
	puts "unable to create table"
end

desc "populate db"
task :populate => [:connect, :create] do
	puts "get data"
end

desc "clobber the db"
task :clobber => [:connect, :drop, :create] do
	puts "clobber it!"
end
