MongoEngine: database names cannot contain the character '.'

Question

I am trying to insert document using mongoengine in my python script but it raises this exception

(<class 'pymongo.errors.InvalidName'>, InvalidName("database names cannot contain the character '.'",), <traceback object at 0x000000000844F708>)

Connection string is mongodb://user:pass@ds042487-a0.mlab.com:42487/db-name

Any suggestions on how to fix this??

Thanks

Can you add the code you're using to connect to the question? — tfogo, Jan 02 '18 at 17:25
from mongoengine import * try: connect(mongodb://user:pass@ds042487-a0.mlab.com:42487/db-name) except Exception as e: print e — Mustafa Khalid, Jan 03 '18 at 07:56

Rather than using

connect("mongodb://user:pass@server_url:port/db-name")

use this

connect( db='db-name', username='user', password='pass', host='mongodb://user:pass@server_url:port/db-name')

It worked for me. :)

Your database name shouldn't contain any of these characters: ' ', '.', '$', '/', '\\', '\x00', '"'

Check your database name. The Mongo driver also enforces this rule so the chance that you have a database with a dot in its name is slim.

I want to add that I found this applies to **collection** names as well – cryanbhu Apr 10 '19 at 04:54
