For testing purposes I'm trying to use SQLite, but it seems I'm missing the spatialite backend:
django.core.exceptions.ImproperlyConfigured: 'django.contrib.gis.backends.spatialite' isn't an available database backend.
Try using django.db.backends.XXX, where XXX is one of:
'dummy', 'mysql', 'oracle', 'postgresql_psycopg2', 'sqlite3'
Error was: No module named backends.spatialite.base
Any idea how I can make Django find it?
I have installed spatialite.
This is my db setup:
DATABASES['default'] = {
'ENGINE': 'django.contrib.gis.backends.spatialite',
'NAME': '/tmp/test.db'
}
Ubuntu 12.04.1 LTS; Python 2.7.3; Django 1.4.1
You should look for:
django.contrib.gis.db.backends.spatialite
not
django.contrib.gis.backends.spatialite
:)

I’m having troubles making Django + PostGIS work on AWS BeanStalk.
The app runs, some parts of the app work properly, but when trying to access object with GeoDjango fields (PointField) I get this error:
Attribute Error
'DatabaseOperations' object has no attribute 'select'
/opt/python/run/venv/lib/python3.4/site-packages/django/contrib/gis/db/models/fields.py
in select_format, line 61
I have googled this error, and very few people encountered it. The closest error I could find is: Getting 'DatabaseOperations' object has no attribute 'geo_db_type' error when doing a syncdb
But my databases is configured correctly in the Django Settings Module as follows:
DATABASES = {
'default': {
'ENGINE': 'django.contrib.gis.db.backends.postgis',
'NAME': os.environ['RDS_DB_NAME'],
'USER': os.environ['RDS_USERNAME'],
'PASSWORD': os.environ['RDS_PASSWORD'],
'HOST': os.environ['RDS_HOSTNAME'],
'PORT': os.environ['RDS_PORT'],
}
}
I’m using Django 1.9.5 with PostGis 2.3.0 and PostgreSQL 9.5.2
I’m using a custom AMI based on 2017.03 that I made using this script:
https://gist.github.com/nitrag/932ecd7d109f9d1e3ed378353e0d5c2f
PostGis is installing properly on the EC2 instance, I even tried another script and got the same final error. (http://www.daveoncode.com/2014/02/18/creating-custom-ami-with-postgis-and-its-dependencies-to-deploy-django-geodjango-amazon-elastic-beanstalk/)
I am really on my last legs here, any help will be greatly appreciated!
i am getting this error when running python manage.py syncdb.
I've tried installing all the packages that were described in various posts to no avail.I desperately want a solution as i have lost too many time in this!
Thanks in advance for any help!
Edit: Also my setting for database is:
DATABASES = {
'default': {
'ENGINE': 'django.db.backends.mysql', # Add 'postgresql_psycopg3', 'mysql', 'sqlite3' or 'oracle'.
'NAME': 'db1', # Or path to database file if using sqlite3.
'USER': 'root', # Not used with sqlite3.
'PASSWORD': 'XYZ', # Not used with sqlite3.
'HOST': 'localhost', # Set to empty string for localhost. Not used with sqlite3.
'PORT': '3306', # Set to empty string for default. Not used with sqlite3.
}
}
My O.S is Linux Mint 17.1 Mate.
Also do i need to install django in a virtual environment?
Try installing this way
apt-get install python-dev libmysqlclient-dev
pip install MySQL-python
Phew!
Got it working at last!
Seems like my Django package was not compatible with libs & dependencies.I created a virtual environment and installed the latest Django package as well as its dependencies, libs etc.
That is it!
I have tried to setup an instance of Django on Jython using Postgresql. I can't get Django to talk to Postgresql. Can someone help me figure out what is wrong?**
So far, I have the following system installed for development:
Windows 7
JDK7 (x86)
Jython Version 2.7b2
Django-1.6.5
django-jython 1.7.0b2(Database backends and management commands, for development underDjango/Jython)
postgresql-9.3.5-1-windows-x64.exe
Eclipse-PyDev
I was able to run the server and database, but now I am having issues with configuring Django to work with the Postgresql database.
I followed the configuration steps here:
https://pythonhosted.org/django-jython/database-backends.html#postgresql
My settings.py file has the following:
DATABASES = {
'default': {
'ENGINE': 'doj.db.backends.postgresql',
'NAME': 'gate',
'USER': 'gate',
'PASSWORD': 'test',
'HOST': '127.0.0.1',
'PORT': '5432',
}
}
When I check my class path:
C:\>echo %CLASSPATH%
C:\Program Files (x86)\Java\jdk1.7.0_67\bin.;C:\Program Files (x86)\Java\jre7\li
b\ext\QTJava.zip
I have the JDBC file postgresql-9.3-1102.jdbc41.jar in the lib folder listed above.
Error Message from Django
File "C:\jython2.7b2\Lib\site-packages\django\db\utils.py", line 131, in load_backend raise ImproperlyConfigured(error_msg)
django.core.exceptions.ImproperlyConfigured: 'doj.db.backends.postgresql' isn't an available

I believe the problem is that you are using the wrong version of Django.
Jython-Django is compatible only starting from 1.7.
See https://docs.djangoproject.com/en/1.6/howto/jython/
[SOLVED] After successfully completing the django tutorial, I have tried to use mongoDB as a database, with Django MongoDB Engine. This is the database configuration in settings.py:
DATABASES = {
'default': {
'ENGINE': 'django_mongodb_engine',
'NAME': 'test',
'HOST': 'localhost',
'PORT': 27017,
# 'OPTIONS' : {
# 'slave_okay' : True,
# }
}
}
And this is the error message I get, after running python manage.py syncdb
:
raise AutoReconnect("could not find master/primary")
pymongo.errors.AutoReconnect: could not find master/primary
I got this error, even after shutting down the mongoDB server, so I figured out that this needed to be a connection issue. I posted an answer on how I solved this.
Using Ubuntu 12.04 LTS x64, Python 2.7, django 1.4.2, mongoDB x86_64 2.2.1 (clean new install)
The way I solved this is so simple that I am almost ashamed at myself for asking the question in the first place, but I hope it will be useful:
I simply upgraded the Django MongoDB Engine by typing into the terminal:
sudo pip install git+https://github.com/django-nonrel/mongodb-engine --upgrade
And that's it.
Can you try running ...
db.repairDatabase()
... from the mongo terminal?
I'm having some issues setting up django-mssql on Win Server 2008 R2. I have everything installed, however, the wiki for django-mssql says to setup the settings file similar to:
DATABASES = {
'default': {
'NAME': 'my_database',
'ENGINE': 'sqlserver_ado',
'HOST': 'dbserver\\ss2008',
'USER': '',
'PASSWORD': '',
'OPTIONS' : {
'provider': 'SQLOLEDB',
'use_mars': True,
},
}
}
When I run from my site directory:
python manage.py syncdb
I get an error stating it isn't an available database backend. When I installed django-mssql it seemed to install the backend here \site-packages\django_mssql-1.0.1-py2.7.egg\sqlserver_ado does this need to be copied to site-packages\django\db\backends?
I get the same error if I set my settings to:
DATABASES = {
'default': {
'NAME': 'my_database',
'ENGINE': 'django_mssql-1.0.1-py2.7.egg.sqlserver_ado',
'HOST': 'dbserver\\ss2008',
'USER': '',
'PASSWORD': '',
'OPTIONS' : {
'provider': 'SQLOLEDB',
'use_mars': True,
},
}
}
Am I missing something when setting up this backend? This is my first time using django, but I didn't see anything in the documentation for setting up a different backend, and the django-mssql wiki or issues doesn't seem to have anything either.
Also, if there is other documentation somewhere that can help please let me know.
EDIT: The django app is running on Ubuntu server.
Dustin's comment about making sure "import sqlserver_ado" from the command shell got me going down the right path on my Django 1.8.1, Python 3.5 Win32 system with pywin32 installed.
SPOILER ALERT This only gets my Django instance to run without errors. I haven't tested the ADO connection yet.
The first error message I got was:
No module named 'django.db.backends.util'
and I found there is a file called: django.db.backends.utils so I copied it and renamed it to django.db.backends.util (without the 's') and away went the error message!
So hoping this wasn't too harmful, I continued on this line of troubleshooting.
The next error message I got was:
File "C:\Program Files (x86)\Python35-32\lib\site-packages\sqlserver_ado\base.py", line 7, in <module>
from django.db.backends import BaseDatabaseWrapper, BaseDatabaseFeatures, BaseDatabaseValidation, BaseDatabaseClient
ImportError: cannot import name 'BaseDatabaseWrapper'
I changed line 7 in base.py to now say:
#from django.db.backends import BaseDatabaseWrapper, BaseDatabaseFeatures, BaseDatabaseValidation, BaseDatabaseClient
from django.db.backends.base.base import BaseDatabaseWrapper
from django.db.backends.base.features import BaseDatabaseFeatures
from django.db.backends.base.validation import BaseDatabaseValidation
from django.db.backends.base.client import BaseDatabaseClient
Yes, that's commenting out the bad line and adding four separate lines.
Then I got this error:
File "C:\Program Files (x86)\Python35-32\lib\site-packages\sqlserver_ado\base.py", line 18, in <module>
from .introspection import DatabaseIntrospection
File "C:\Program Files (x86)\Python35-32\lib\site-packages\sqlserver_ado\introspection.py", line 3, in
from django.db.backends import BaseDatabaseIntrospection
ImportError: cannot import name 'BaseDatabaseIntrospection'
so I changed the line 3 to now read:
from django.db.backends.base.introspection import BaseDatabaseIntrospection
and so on for creation.py:
from django.db.backends.base.creation import BaseDatabaseCreation
for operations.py:
from django.db.backends.base.operations import BaseDatabaseOperations
for schema.py:
from django.utils.log import getLogger
Hope this helps someone. Hope the ADO module actually connects to something.

You will want to make sure that you can import "sqlserver_ado" from your python shell.
Put the folder sqlserver_ado somewhere on your PATH, I put mine in \site-packages\
Take a look at the README.txt.
The engine does want to be set to "sqlserver_ado" similar to how the settings are done on the settings sample page.
As of 2019:
I couldn't get Django MSSQL to work at all.
I switched over to django-pyodbc-azure and that works great.
Install:
pip install django-pyodbc-azure
Setup:
'ENGINE': 'sql_server.pyodbc'
You need to install the dependency PyWin32. You can install via pip or download from the python binaries page http://www.lfd.uci.edu/~gohlke/pythonlibs/
I was trying to get django_pyodbc to work, and couldn't. I was getting this error:
django.core.exceptions.ImproperlyConfigured: 'django_pyodbc' isn't an available database backend.
Try using 'django.db.backends.XXX', where XXX is one of:
u'base', u'mysql', u'oracle', u'postgresql_psycopg2', u'sqlite3'
Error was: cannot import name BaseDatabaseWrapper
I was directed to this post as a solution, so I'll post my answer here also.
I downgraded to django 1.6 instead of 1.8, and now django_pyodbc works as a database backend.
As per https://github.com/lionheart/django-pyodbc/pull/96, django_pyodbc should now work with Django 1.8. So this seems to be a good alternative to django-mssql for those requiring SQL Server 2008 R2 support.
