Example
Connect to Database
>>> import nmongo >>> db = nmongo.connect('servername', 'somewhatdatabase') >>>
SSL connection
>>> import nmongo >>> db = nmongo.connect('servername', 'somewhatdatabase', use_ssl=True) >>>
or
>>> import nmongo >>> db = nmongo.connect('servername', 'somewhatdatabase', use_ssl=True, ssl_ca_certs='/path/to/something-cert.crt) >>>
User Authentication
>>> import nmongo >>> db = nmongo.connect('servername', 'somewhatdatabase', user='user', password='password') >>>
Connect to Azure CosmosDB (MongoDB API)
>>> import nmongo >>> db = nmongo.connect('xxx.mongo.cosmos.azure.com', 'somewhatdatabase', user='xxx', password='password', port=10255, use_ssl=True) >>>
Create
>>> db.fruits.insert({'name': 'apple', 'price': 200}) 1 >>> db.fruits.insert([{'name': 'orange', 'price': 100}, {'name': 'banana', 'price': 50}]) 2 >>> db.fruits.count() 3 >>>
Read
>>> cur = db.fruits.find({'name': 'banana'}) >>> cur.fetchone() {'price': 50, '_id': ObjectId("5826b2313d28909ce9f6ea63"), 'name': 'banana'} >>> cur = db.fruits.find() >>> cur.fetchall() [{'price': 200, '_id': ObjectId("5826b2273d28909ce9f6ea61"), 'name': 'apple'}, {'price': 100, '_id': ObjectId("5826b2313d28909ce9f6ea62"), 'name': 'orange'}, {'price': 50, '_id': ObjectId("5826b2313d28909ce9f6ea63"), 'name': 'banana'}] >>>
Update
>>> db.fruits.update({'name': 'banana'}, {'$inc': {'price': 20}}) {'nModified': 1, 'ok': 1, 'n': 1} >>> cur = db.fruits.find({'name': 'banana'}) >>> cur.fetchone() {'_id': ObjectId("5823dd6d3d28909ce9f6e99c"), 'name': 'banana', 'price': 70} >>>
Delete
>>> db.fruits.remove({'name': 'banana'}) 1 >>> db.fruits.count() 2
Count each collection records
>>> for collection in db.getCollections(): ... print(collection.name, collection.count()) ... fruits 3 >>> db.getCollection('fruits').count() 3 >>>
