I am using django with mongoengine. I am writing the following in the settings.py file:
from mongoengine import connect
URI = 'mongodb+srv://myusername:mypassword@cluster0.5apjp.mongodb.net/django?retryWrites=true&w=majority&ssl=false'
connect(host=URI)
After that, I have a model as follows:
from mongoengine import Document, StringField
class User(Document):
first_name = StringField(max_length=50)
last_name = StringField(max_length=50)
meta = {
'collection': 'users'
}
I have a view as follows:
def adduser(request):
userDict = json.loads(request.body)
newUser = User(first_name=userDict['firstName'],last_name=userDict['lastName'])
newUser.save()
return HttpResponse('user added')
When this view function is called, I get an error as follows:
ServerSelectionTimeoutError(

I am using a mongodb free M0 cluster with database named as 'django' and collection named as 'users'.
If I use a non-SRV URI string like localhost:27017, it works fine. But when I use a SRV URI, its giving me this error.
Moreover, I have added 0.0.0.0/0 in the IP access list of Network Access tab of MongoDB Atlas UI.
Please help me to get rid of this error so that I can proceed with basic CRUD operations on MongoDB using Django with MongoEngine.
Of course I need to remove ssl=false
. But that does not fix my issue. I was getting SSL certificate error after that. From the MongoDB Developer Community, I got to know that my OS system certs are out of date and need to be updated. One can update them or can override them via certifi
as follows:
python -m pip install --upgrade certifi
And then in my settings.py,
import certifi
from mongoengine import connect
URI = 'mongodb+srv://...'
connect(host=URI, tlsCAFile=certifi.where())
Now it is working fine completely.
