Play python with twitter streaming

I was interested in how to do twitter streaming. I tried to find out on the internet and got many examples. I tested it with python code(tweepy). I got data in JSON format. I thought it's a good idea, if I was able insert this data into mongodb.
So. I created my application on twitter and tested some a little bit code.

[surachart@centos ~]$ ./mongo/bin/mongo
MongoDB shell version: 2.2.2
connecting to: test
>
> db.twittertest.find()
> db.twittertest.find()

Used some code on the internet and changed a bit to insert data into database.

[surachart@centos ~]$ cat ./test-tweeter.py
#!/usr/bin/python
import tweepy
import pymongo
import json

consumer_key = "..."
consumer_secret = "..."
access_token_key = "..."
access_token_secret = "..."


auth1 = tweepy.OAuthHandler(consumer_key, consumer_secret)
auth1.set_access_token(access_token_key, access_token_secret)

class StreamListener(tweepy.StreamListener):
    def on_status(self, tweet):
        print tweet.text

    def on_error(self, status_code):
        print 'Error: ' + repr(status_code)
        return False

    def on_data(self, data):
        print 'Ok! Inserting Data.'
        from pymongo import MongoClient
        client = MongoClient()
        client = MongoClient('localhost', 27017)
        db = client.test
        test_id = db.twittertest.insert(json.loads(data))

l = StreamListener()
streamer = tweepy.Stream(auth=auth1, listener=l)
streamer.filter(track=['oracle'])

I filtered by using word 'oracle'.

[surachart@centos ~]$ ./test-tweeter.py
Ok! Inserting Data.

I was able to insert data...  and I will play with it later.
