i think below setting will work for the djongo to connect to the remote mongodb on mongodb.com but, the error message shows its still trying to connect to the localhost
DATABASES = {
'default': {
'ENGINE': 'djongo',
'HOST': 'mongodb+srv://<username>:<password>#cluster-name/<dbname>?retryWrites=true&w=majority',
}
below is the error traceback

I have met your problem before. In my case, I run django & mongodb inside containers. And I found that whatever setting I set inside setting.py, the djongo(they use pymongo behind) just ignore my setting.
For others seeking for the solution, you may want to check your syntax in setting.py which should look like below:
DATABASES = {
'default': {
'ENGINE': 'djongo',
'NAME': 'your-db-name',
'ENFORCE_SCHEMA': False,
'CLIENT': {
'host': 'host-name or ip address',
'port': port_number,
'username': 'db-username',
'password': 'password',
'authSource': 'db-name',
'authMechanism': 'SCRAM-SHA-1'
},
.......
}
Detail from djongo document
You can see the host, user, password fields are all under 'CLIENT' , which is different with the default syntax described by Django. So maybe most people get confused here and stuck at this problem.
Go to settings.py file and use below Database settngs
DATABASES = {
'default': {
'ENGINE': 'djongo',
'ENFORCE_SCHEMA': True
'NAME': 'your-db-name',
'HOST': 'host-name or ip address',
'PORT': port_number,
'USER': 'db-username',
'PASSWORD': 'password',
'AUTH_SOURCE': 'db-name',
'AUTH_MECHANISM': 'SCRAM-SHA-1',
}
Please also check out this article for connection between django and mongo db.
https://medium.com/#ksarthak4ever/how-to-use-django-with-mongodb-40ba36a21124
I personally recommend you please use pycharm. In Pycharm you can test your connection. So that you can get more clear image of whole scenario.
I use remote database in django. you can see in the below picture
I GOT THE SOLUTION
I adopted following approach >
so, behind the scene the djongo uses -> pymongo
and pymongo's default configuration are
class MongoClient(common.BaseObject):
HOST = "localhost" # here HOST has the hardcoded value
PORT = 27017
which lies in following file
venv/lib/python3.6/site-packages/pymongo/mongo_client.py
replace the harcoded value of HOST to something like
HOST = 'mongodb+srv://<username>:<password>#cluster-name/<dbname>?retryWrites=true&w=majority'
ADDITIONALLY
We can set the environment variable if we want
HOST = os.getenv('MONGO_DB_URL')

I am trying to migrate my Django model to the AWS Lightsail database, but I am getting below error. My database is on AWS Lightsail. it is PostgreSQL. I am deploying my project on AWS so I have set up almost everything except model migration.

"HOST" should be the hostname, not the port!
"NAME" is the name of the database.
An example from the Django documentation:
'ENGINE': 'django.db.backends.oracle',
'NAME': 'xe',
'USER': 'a_user',
'PASSWORD': 'a_password',
'HOST': 'dbprod01ned.mycompany.com',
'PORT': '1540',
I am running datastore emulator. When I run "dev_appserver.py app.yaml" command, I get this error

It seems that your Default service account does not have enough permissions. It might require some additional permissions such as "Datastore Index Admin" to infer over a Datastore[1]. I am not sure on how this will work in the Datastore emulator, but since it aims to provide a local emulation, maybe it will get the roles and permission to perform a test. Could you please check the permissions in your service account[2], change if needed and let me know if the issue persists. I will be waiting for your reply.

Edit skip first part, I found out (well, they tell me) that the problem is in the database \edit
I Have a python+django project that I keep on two computers. I mean have two copy of the same project and sometimes I work on one, sometimes on the other. With copy-paste I lose the secret key in a settings.py (they were different but I overwrite). I don't know how generation and storage of secret keys works but to recover I start a new project, took the key and copied the files like this:
1) make a copy of the project
2) deleted the original project but kept the copy
3) started a new project with the same name (so, in the same folder like the original)
4) copied the new secret key
5) copied the files from the copy of the old project in the new project (so settings.py is lost and the new secret key with it, but I have a copy)
6) changed the secret key with the new secret key
But this don't works and it gives the same error like before:
System check identified no issues (0 silenced).

django.db.utils.OperationalError: FATALE: autenticazione con password fallita p
er l'utente "gm"
translated: authentication with password failed for user 'gm'
I'm not sure when it happened the first time but I have another problem, probabily linked: I can't access the database. Maybe this is the cause of the first problem and not the secret key.
I use PostgreSQL and I access it using the utility standard pgAdmin III. It gives me the initial screen with Servers: PostgreSQL 9.5, I right click on it and select connect, it ask me for password, I gives but it throws an error:
An error has occurred. Error connecting to the server: FATALE: autenticazione con password fallita per l'utente 'postgres'.
translated: authentication with password failed for user 'postgres'
I have created only one database and user so I have the standard postgres and my database 'possedimenti_db' with an user called 'gm'.
What can I do? I don't mind the data present, I can delete all but if it don't make me access I don't know how to delete.
Thank you
My settings.py:
DATABASES = {
'default': {
'ENGINE': 'django.db.backends.postgresql',
'NAME': 'possedimenti_db',
'USER': 'gm',
'PASSWORD': database_key,
'HOST': host_key,
'PORT': '5432',
}
}
database_key and host_key are imported from external file.
Also database_key is different from the password I use to access the database with pgAdmin. In my other pc it works. I tried to change it in the other password but it throws anyway the same error.
Edit
You Can read the solution in the comments of the answer but the problem was that my user hadn't a password definited.
Use 'django.db.backends.postgresql_psycopg2' instead of 'django.db.backends.postgresql'.
you have to install psycopg2. Use this command:
pip install psycopg2
Here is the example:
DATABASES = {
'default': {
'ENGINE': 'django.db.backends.postgresql_psycopg2',
'NAME': 'team_db',
'USER': 'jason',
'PASSWORD': 'abcd',
'HOST': 'localhost',
'PORT': '5432',
}
}
I have a Django app with a worker process which does database transactions. Under the hood, I have an Azure SQL database attached to my application. The worker code looks something like this:
class Command(BaseCommand):
def handle(self, *args, **kwargs):
os.environ.setdefault('DJANGO_SETTINGS_MODULE', 'project.settings')
django.setup()
consumer = Consumer()
logging.info('Booting drive consumer')
while True:
messages = consumer.poll()
for message in messages:
...
DriveEvent.objects.create(event_id=response['Id'], drive_id=drive_payload['drive_id'])
...
After about 20 mins, the create db object calls start failing with the following error:

Database init (in settings.py) looks something like this:
DATABASES = {
'default': {
'ENGINE': 'sql_server.pyodbc',
'NAME': os.environ.get('DB_NAME'),
'HOST': os.environ.get('DB_HOST'),
'PORT': '1433',
'USER': os.environ.get('DB_USER'),
'PASSWORD': os.environ.get('DB_PASSWORD'),
'OPTIONS': {
'host_is_server': True,
'driver_supports_utf8': True,
'extra_params': 'tds_version=7.2;'
}
}
}
Per my experience, it seems to be caused by the tds_version that the 7.2 version does not support Azure SQL Database. Please refer to my answer for the other SO thread pymssql: Connection to the database only works sometimes to change to 7.3.
Possibly, the third-party project michiya/django-pyodbc-azure on GitHub may help for you to get the more details.
Hope it helps.
I'm trying to use django-mssql to connect to MS SQL Server 2008 R2 with Django 1.4.2 These are my Database settings:
DATABASE_ENGINE = 'sqlserver_ado'
DATABASE_NAME = 'dbtest'
DATABASE_USER = 'App'
DATABASE_PASSWORD = '*********'
DATABASE_HOST = 'localhost'
DATABASE_OPTIONS = {
'provider': 'SQLNCLI10',
'extra_params': 'DataTypeCompatibility=80;MARS Connection=True;',
}
DATABASES = {
'default': {
'ENGINE': DATABASE_ENGINE,
'NAME': DATABASE_NAME,
'USER': DATABASE_USER,
'PASSWORD': DATABASE_PASSWORD,
'HOST': DATABASE_HOST,
'OPTIONS' : DATABASE_OPTIONS,
},
}
This is the error I get when I try to syncdb
Traceback (most recent call last):

I've looked everywhere and I cannot seem to understand and fix the problem. I hope someone can help!
Thanks!
Edit:
I've already created the database. I've also connected to the database using django-pyodbc, and I've successfully read and written from the database. But django-pyodbc causes problems when I use Apache, which was why I decided to try django-mssql. However, I do not understand the error it comes up with.
My Django (1.4.2) and Python (2.7) installs run on Windows, and I'm using an Apache webserver.
Update pywin32 to build 217 or greater. I found another question on stackoverflow with the same issue (on another topic):
Python COM server throws 'module' object has no attribute 'VARIANT'
