MongoLab błąd połączenia/PyMongo

Question

Jeśli uruchomić w powłoce:

mongo ds0219xx.mlab.com:219xx/dbname -u user -p pass 

To działa i pozwala mi połączyć się z bazą danych i wyciągnąć informacje. Ale jeśli jestem w moim aplikacji Pythona (kolba) i uruchomić to:

import pymongo 

client = pymongo.MongoClient("mongodb://user:pass@ds0219xx.mlab.com:219xx/dbname") 

db = client["dbname"] 

db.users.insert_one({ 
    "user1": "hello" 
}) 

To daje mi:

pymongo.errors.OperationFailure: Authentication failed. 

Jestem całkiem pewien, że w przypadku braku zanim dojdzie do insert_one() zadzwoń, ale nie jestem całkowicie pewien.

Dzięki!

Edit: Wnioskiem, tutaj jest pełna zwrotna:

pymongo.errors.OperationFailure: Uwierzytelnianie nie powiodło się.

Wymyśliłem to. Możesz to zrobić z pliku Pythona i zadziała:

connection = pymongo.MongoClient(ab123456.mlab.com, 123456) 
db = connection[databasename] 
db.authenticate(database_user, database_pass)
