write to database with tweetstream daemon

Question

I am trying to write all tweets that matches a keyword to my database. I have set up the following in tracker.rb:

require 'rubygems'
require 'tweetstream'

TweetStream::Daemon.new('Bill Gates','money','Twitter Tracker').track('ladygaga') do |status|
  Tweet.new(:content => status.text)
end

But nothing happens. What am I doing wrong here?

Thanks in advance

Update: I put everything in a .rake file called twitter.rake and start the demon with $ rake scrap:

task :scrap => :environment do
  desc "Run Twitter Scraper"
  TweetStream::Client.new('TWITTER_USER','TWITTER_PASS').track('ladygaga') do |status|
    Tweet.create(:user_id  => status.user.id, :user_screen_name => status.user.screen_name, :user_profile_image_url => status.user.profile_image_url, :status_text => status.text, :status_id => status.id)
    puts "[#{status.user.screen_name}] #{status.text}"
  end
end

How are you calling the Daemon?

You need to supply a command (start/stop..)

For example:

rails runner "TweetStream::Daemon.new('tracker').track('ladygaga') { |status| do_something }" start

This would start the job in the background
