Pymongo

Okay Here We Go

On this page we show how to set up a connection to the MongoDB.

Start mongodb

Fire up mongodb:

$ mongod -f /usr/local/etc/mongodb.conf

Start python

Fire up Python:

>>> from pymongo import MongoClient
>>> client = MongoClient('localhost', 27017)

Now you're connected to the local MongoDB daemon, and you can interact with the database.

Create database and collections

If you have a MongoDB client, you must start by getting a database (create one if it does not exist), in this case one called test_database:

>>> db = client.test_database

Now that you have a database, you can get a collection (create one if it does not exist):

>>> collection = db.test_collection

Inserting data into collections

Finally, once you have a collection you can start to add documents to it:

>>> doc = { 'bssid' : 'aa:bb:cc:dd:ee:ff:00:11', 'channel' : 5, 'ssid' : 'Nacho Wifi', 'strength' : -20, 'encryption' : 'WPA' }
>>> 

(SQL analogy: once you have a database, you can start to add tables. Once you have tables, you can start to add records/rows to the tables.)

To monitor the whole process, add the following line to your config file, so that mongodb will print out more info about what's going on:

systemLog:
  path: /usr/local/var/log/mongodb/mongo.log
  verbosity: 2

Now, as you perform operations on mongodb in Python, you can run tail -f /usr/local/var/log/mongodb/mongo.log in another window, and monitor to ensure that everything is working as expected.
