Ruby Tweetstream MongoDB Error -

i keep getting following error when running following ruby script. if can me fix appreciated. i've removed sensitive data such api keys.

code:

#!/usr/bin/env ruby require "tweetstream" require "mongo" require "time"  tweetstream.configure |config|   config.consumer_key       = 'key'   config.consumer_secret    = 'secret'   config.oauth_token        = 'token'   config.oauth_token_secret = 'token_secret'   config.auth_method        = :oauth end  db = mongo::connection.new("ds045037.mongolab.com", 45037).db("tweets") auth = db.authenticate("db_username", "db_password") tweets = db.collection("tweetdata")  tweetstream::daemon.new("twitter_username", "twitter_password").track("term") |status|   # things when nothing's wrong   data = {"created_at" => time.parse(status.created_at), "text" => status.text, "geo" => status.geo, "coordinates" => status.coordinates, "id" => status.id, "id_str" => status.id_str}   tweets.insert({"data" => data}); end 

command start script:

ruby tweetscrape.rb 

ruby version:

ruby 1.9.3p429 (2013-05-15 revision 40747) [x86_64-linux] 

ruby -c tweetscrape.rb produces:

syntax ok 

error message:

edit: have no errors using below nothing entered in mongodb:

#!/usr/bin/env ruby require "tweetstream" require "mongo" require "time"  tweetstream.configure |config|   config.consumer_key       = 'gfdsgfdsgfdsgfdsgfdsgfds'   config.consumer_secret    = 'gfsdgfdsgfdsgfdsgfsdgfd'   config.oauth_token        = 'gfdgfdsgfsdgfdsgfsdgf'   config.oauth_token_secret = 'hsgfsdgfsdgfsdgfds'   config.auth_method        = :oauth end  db = mongo::connection.new("ds045037.mongolab.com", 45037).db("tweets") auth = db.authenticate("gfsdgfdsgfsd", "gfdsgfdsgfdsgfsd") tweets = db.collection("tweetdata")  tweetstream::client.new.track('term') |status|   puts status.text   data = {"created_at" => time.parse(status.created_at), "text" => status.text, "geo" => status.geo, "coordinates" => status.coordinates, "id" => status.id, "id_str" => status.id_str}   tweets.insert({"data" => data}) end 

tweets show on screen through puts though...

the initial error getting daemon class because you're not passing correct parameters constructor. contructor takes string , hash.

moving on , insert failed because:

1. parsing status.datetime throws exception (its time object).
2. status.coordinate throws exception if there's no coordinate.

the following code works me (note : added growl can see tweets):

#!/usr/bin/env ruby require "tweetstream" require "mongo" require "time" require 'growl'  desired = %w{created_at text geo coordinates id id_str} host= env["mongo_host"]  || 'localhost' port = env["mongo_port"]  || 27017 username = env["mongo_username"] password = env["mongo_password"]  term = argv[1] || 'term'  begin   tweetstream.configure |config|     config.consumer_key       = env["tweet_consumer_key"]     config.consumer_secret    = env["tweet_consumer_secret"]     config.oauth_token        = env["tweet_oauth_token"]     config.oauth_token_secret = env["tweet_oauth_token_secret"]     config.auth_method        = :oauth   end    db = mongo::connection.new(host, port).db("tweets")   db.authenticate(username, password)   tweets = db.collection("tweetdata")    puts "about start tracking term #{term}"   tweetstream::daemon.new('tracker').track(term) |status|     growl.notify status.text, :title => status.user.screen_name      #     # filter out nil values     # filter out keys not in desired array     #     data = status.attrs.select{|k,v| !v.nil? && desired.include?(k.to_s)}     tweets.insert({"data" => data});   end  rescue mongo::connectionfailure   puts "connection error :  #{$!}" rescue mongo::authenticationerror   puts "auth error :  #{$!}" rescue mongo::mongodberror   puts "unexpected error :  #{$!}" end 

you'll need setup environment following correct values :

export mongo_username="..." export mongo_password="..." export tweet_consumer_key="..." export tweet_consumer_secret="..." export tweet_oauth_token="..." export tweet_oauth_token_secret="..." 

then can start daemon (in case we'll search yankees):

ruby tweetscrape.rb start yankees
