Hi, I want to use the TweetStream gem
http://github.com/intridea/tweetstreamin my Rails app
I can''t seem to figure out how to do it, because it opens a connection
and
then won''t move on.
I got it to work in a Ruby script with
---------- start code ----------
require ''rubygems''
require ''tweetstream''
user = ''blinkdev''
password = **secret**
keyword = ''#ROCKPIC''
Thread.new do
TweetStream::Client.new(user,password).track(keyword) do |status|
puts "[#{status.created_at}-#{status.user.screen_name}]
#{status.text}"
end
end
loop do
sleep 10
puts "other stuff happening"
end
---------- end code ----------
Which gives the output:
other stuff happening
other stuff happening
[Mon Mar 01 20:30:59 +0000 2010-blinkdev] test #ROCKPIC 7
other stuff happening
So I tried to replicate that in my Rails app in the file
config/initializers/twitter_stream.rb
---------- start code ----------
require ''rubygems''
require ''tweetstream''
Thread.new do
logger.info "started tweetstream"
TweetStream::Client.new(''blinkdev'',**secret**).track(''#ROCKPIC'')
do
|status|
message = "[#{status.created_at}-#{status.user.screen_name}]
#{status.text}"
logger.info message
logger.info Rockpic.new( :message => message ).save!
end
end
---------- end code ----------
But it didn''t work. I couldn''t get it to log anything either.
So I went and
tried it in the console:
---------- start code ----------
$script/console
Loading development environment (Rails 2.3.3)>> require ''rubygems''
=> []>> require ''tweetstream''
=> []>>
?> Thread.new do
?> logger.info "started tweetstream">>
?>
TweetStream::Client.new(''blinkdev'',**secret**).track(''#ROCKPIC'')
do
|status|
?> message = "[#{status.created_at}-#{status.user.screen_name}]
#{status.text}">> logger.info message
>> logger.info Rockpic.new( :message => message ).save!
>> end
>>
?> end
=> #<Thread:0x24ba60c dead>
---------- end code ----------
It doesn''t seem to do anything. I tried playing with daemons, but I
can''t
figure out how to use them either.
If someone can show me how to use daemons, I''ll give that a try (I have
the
daemons gem installed http://rubygems.org/gems/daemons) and it looks like
TweetStream has their own version with Daemons,
http://rdoc.info/rdoc/intridea/tweetstream/blob/e5ecb9ef125ebce038d24f816973bbb4644445a8/TweetStream/Daemon.htmlbut
I can''t seem to get it to do anything:
---------- start code ----------
ARGV << ''start''
require ''rubygems''
require ''tweetstream''
user = ''blinkdev''
password = **secret**
keyword = ''#ROCKPIC''
TweetStream::Daemon.new(user,password,
''tracker'').track(keyword) do |status|
puts "[#{status.created_at}-#{status.user.screen_name}]
#{status.text}"
end
---------- end code ----------
It runs, but it doesn''t respond to anything, and I think I need it to
run in
the Rails environment, because I want to host it on Heroku. Anyway, I''m
not
sure where to go with it, I just want my Rails app to have a stream to
twitter to watch for a given hash tag, and a particular user''s tweets.
Any help would be appreciated.

Based on their example, I got this to work:
---------- start code ----------
require ''rubygems''
require ''tweetstream''
require ''ruby-growl''
username = ''blinkdev''
password = **secret**
tracks = [''#ROCKPIC'']
puts "Starting a GrowlTweet to track: #{tracks.inspect}"
TweetStream::Daemon.new(username,password).track(*tracks) do |status|
g = Growl.new ''localhost'', ''growltweet'',
[''tweet'']
g.notify ''tweet'', status.user.screen_name, status.text
end
---------- end code ----------
And run it from the command line like
$ruby test.rb start
$ruby test.rb stop
So I want to pull that into my rails app, I wrote this file to load the
environment, and save the statuses
---------- start code ----------
# file: RAILS_ROOT/jobs/twitter_stream.rb
ENV[''RAILS_ENV''] = ARGV.shift
require File.expand_path(File.dirname(__FILE__) +
"/../config/environment")
require ''rubygems''
require ''tweetstream''
username = ''blinkdev''
password = **secret**
tracks = [''#ROCKPIC'']
TweetStream::Daemon.new(username,password).track(*tracks) do |status|
Rockpic.new( :message =>
"[#{status.created_at}-#{status.user.screen_name}] #{status.text}"
).save!
end
---------- end code ----------
and then to load it, I created
---------- start code ----------
# file: RAILS_ROOT/config/initializers/twitter_stream.rb
puts ''pre''
system "#{%x(which ruby).chomp}
#{File.join(RAILS_ROOT,''jobs'',''twitter_stream.rb'')}
#{ENV[''RAILS_ENV'']}
restart"
puts ''post''
---------- end code ----------
But it never finishes that command, when I start my server it just keeps
writing ''pre'' over and over, implying to me that it is
recursively calling
itself. ie the initializer starts the daemon, which requires the
environment, which runs the initializer, which starts the daemon, etc.
I figure if I can get it to realize that it is already running, then I
should be good, but I''m not very experienced with this, and
don''t know how
to check for that. Api doesn''t look like it offers a way, but looking
at the
code shows that it uses Daemons underneath of it. Not sure how to do it,
still, though. Any help is appreciated.

Hi Josh, If your overall goal is to run it as a background task on Heroku, I think you want this: http://docs.heroku.com/background-jobs. I don''t think that there''s any other way to run background jobs on Heroku.
