I am trying to connect mongodb with django, but i am getting this error
ImproperlyConfigured: 'djongo' isn't an available database backend.
Try using 'django.db.backends.XXX', where XXX is one of:
'mysql', 'oracle', 'postgresql_psycopg2', 'sqlite3'
I have read posts but they are all old and not helping me. I have created mongodb database using studio 3T, name of database is NewDataBase user is gsc-30310 port is 27017 host is localhost
Versions I am using are:
python3
Django==2.1.1
mongoengine==0.15.3
pymongo==3.7.1
Here is my settings.py file, please tell me how to setup for new version of django and python 3. thanks

Django works well with Relational databases like PostGreSQL, MySQL. Every django settings needs to have a Database configuration defined with 'default' configurations it also needs database respective engine like psycopg2 for PostGreSQL, mysqlclient for MySQL - if you have multiple database configurations then you need to use database router check here for reference. In case of MongoDB - its a NoSql database which Django officially doesn't support if you really need to use MongoDB create a mongoengine configuration in views and you can define mongo credentials in settings.py
Using pymongo in django views:
client = pymongo.MongoClient(MONGO_URI)
mongodb = client[MONGO_DB_NAME]
...
class MongoClassView(View):
def post(request):
...
mapped_data = {'name': 'John'}
mongodb.get_collection('mycollection').insert(mapped_data)
return JsonResponse({})
hope this helps
You can try these steps to connect your django 2.0 or more with MongoDB database:
1) Install mongoengine for django 2.0
pip install -e git+https://github.com/MongoEngine/django-mongoengine.git#egg=django-mongoengine
2)Add these in your settings file:
from mongoengine import *
'django_mongoengine', // Add this line to installed app
MONGODB_DATABASES = {
"default": {
"name": '<db_name>',
"host": 'localhost',
"password": '',
"username": '',
"tz_aware": True, # if you using timezones in django (USE_TZ = True)
},
}
You can find the details for querying the database here
first thank you for your answers and support in this question.
I agree with Sanchit and shreesh katti answers, we can use mongoclient and mongoengine to connect with MongoDB, both works good.
I have found one another way, there is an open source project djongo
and I am using djongo
to connect with MongoDB
database. The main benefit of djongo
is that it lets you use everything that django
provides ( eg models.Model).
here is link of djongo
GitHub page https://github.com/nesdis/djongo
this is settings that we need to use djongo settings.py
DATABASES = {
'default': {
'ENGINE': 'djongo',
'NAME': 'MyDB',
}
}
Use mongoengine and djongo to connect. Make the following changes in your settings.py file
mongoengine.connect(
db=config.main_db,
host=config.host,
#username=config.username_admin,
#password=config.password_admin,
#authentication_source=config.authSource_admin,
#authentication_mechanism=config.authenticationMechanisms)
DATABASES = {
'default': {
'ENGINE': 'djongo',
'NAME': config.main_db,
# 'USER': config.username_admin,
# 'PASSWORD': config.password_admin,
# 'HOST': config.host,
# 'PORT': config.port,
}
}
use djongo to connect to your mongodb: use these versions on your venv (if you want to use virtual env):
dataclasses==0.1
Django==2.0
djongo==1.2.30
pymongo==3.2
pytz==2018.5
sqlparse==0.2.3
and follow this: Connect MongoDB to Django (using djongo)
