MongoLab/PyMongo errore di connessione

Question

Se corro nella shell:

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

Funziona e mi permette di connettersi al database e tirare le informazioni. Ma se io sono nel mio applicazione Python (Flask) ed eseguire questo:

import pymongo 

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

db = client["dbname"] 

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

Mi dà un:

pymongo.errors.OperationFailure: Authentication failed. 

Sono abbastanza sicuro che è mancato prima che arrivi al insert_one() chiama, ma non ne sono completamente sicuro.

Grazie!

Edit: Su richiesta, ecco il callback completa:

Answer 1

L'ho capito. Puoi farlo dal file python e funzionerà:

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