On the command line, this works:
$ mongo
> show dbs
mydatabase 1.0GB
However, this does not:
$ python
>>> import pymongo
>>> connection = pymongo.MongoClient()
>>> connection.mydatabase.find()
I read through docs here:
http://api.mongodb.org/python/current/tutorial.html
But do not understand how to either...
Why can't I access my database?
To get all the Documents of the Collection use find() method. The find() method takes a query object as a parameter if we want to find all documents then pass none in the find() method.
The first step to connect python to Atlas is MongoDB cluster setup. Next, create a file named pymongo_test_insert.py in any folder to write pymongo code. You can use any simple text editor like Textpad/Notepad. Use the connection_string to create the mongoclient and get the MongoDB database connection.
The question implies user has a local MongoDB. However I found this question trying to connect to a remote MongoDB. I think the tutorial is worth mentioning (no other answer here mentioned how I can specify the host and the port)
The above code will connect on the default host and port. We can also specify the host and port explicitly, as follows:
client = MongoClient('localhost', 27017)
Or use the MongoDB URI format:
client = MongoClient('mongodb://localhost:27017/')
Connect to an existing database
import pymongo
from pymongo import MongoClient
connection = MongoClient()
db = connection.mydatabase
List existing databases
import pymongo
from pymongo import MongoClient
connection = MongoClient()
# connection.database_names() # depreciated
connection.list_database_names()
