For dealing with module named Djongo for connecting Django with MongoDb , one should be completely aware of the modules versions being used in the environment.
Make sure your using the library versions stated below.
asgiref==3.5.0,
Django==4.0.3,
djongo==1.3.6,
dnspython==2.2.1,
pykerberos==1.2.4,
pymongo==3.12.1,
python-snappy==0.6.1,
pytz==2022.1,
sqlparse==0.2.4,
configure the Database settings in the settings.py. Its not necessary to use host while connnecting to the localhost of MongoDb.
DATABASES = {
'default': {
'ENGINE': 'djongo',
'NAME': 'your-db-name',
}
}
