Python Question

pymongo auth failed in python script

I have installed mongodb and enabled auth. and its working find. I can connect it from remote notebook using robomongo application:

Host: SERVER_IP
PORT: 27017
DATEBASE: prod-db
USERNAME: user_name
PASS: user_password
Auth Mechanism: MONGODB-CR


and We can connect from server shell locally using:

$ mongo prod-db -u user_name -p user_password


Everything works fine, but when we try it using pymongo api. authentications failed. below is the python code:

from pymongo import MongoClient

client = MongoClient()
client.prod_db.authenticate('user_name', 'user_password', mechanism='MONGODB-CR')
db = client.prod_db
result = db.users.find()

for document in result:
print(document)


Tools used:

python 2.7
pymongo versiob 3.3.1
MongoDB shell version: 2.6.10
$ mongod --version
db version v2.6.10

Solution:
problem was with database name, following code works fine:

from pymongo import MongoClient

client = MongoClient('mongodb://user_name:user_password@localhost:27017/prod-db')
db = client['prod-db']

result = db.users.find()
for document in result:
print document

Answer

Please try something like this:

client = MongoClient("mongodb://user_name:user_password@SERVER_IP/prod-db")
db = client['prod-db']
