Django-pyodbc mssql error for dumpdata

Question

I am trying to perform a sudo ./manage.py dumpdata on a mssql db from my django project, but keep getting:

Traceback (most recent call last):
  File "./manage.py", line 10, in <module>

pyodbc.Error: ('IM002', '[IM002] [unixODBC][Driver Manager]Data source name not found, and no default driver specified (0) (SQLDriverConnect)')

I have done the configuration mentioned in https://code.google.com/p/django-pyodbc/wiki/FreeTDS, and I get all the test working (FreeTDS & ODBC).

Here is my current settings.py database config:

DATABASES = {
    ...
    'vcoe':
        {
            'ENGINE' : 'sql_server.pyodbc',
            'NAME' : 'VOIP',
            'USER' : '******',
            'PASSWORD' : '******',
            'OPTIONS' : {
                'driver': 'FreeTDS',
                'dsn': 'VCOE',
            }
        }
}

DATABASE_ENGINE = 'sql_server.pyodbc'
DATABASE_NAME = 'VOIP'
DATABASE_USER = '******'
DATABASE_PASSWORD = '******'
DATABASE_OPTIONS = {
    'driver': 'FreeTDS',
    'dsn': 'VCOE', # ODBC DSN name defined in your odbc.ini
}

When I try and run ./manage.py test I get:

I have tried to remove the DATABASES = {...} section and only leave the DATABASE_XXX but get:

django.core.exceptions.ImproperlyConfigured: settings.DATABASES is improperly configured. Please supply the ENGINE value. Check settings documentation for more details.

Im currently using on client:

You're using a very, very old version of django-pyodbc that is no longer maintained. That was last updated in 2011. I've had problems with older versions and using dumpdata and dbshell. I would recommend using this version, actively maintained, which has been working wonderfully for me in several Django projects:

https://github.com/michiya/django-pyodbc-azure

Note, to install it, you'll have to do this, since you're not using Django 1.8:

pip install django-pyodbc-azure<1.8

Off-topic: I'd recommend using Django 1.8.x if you're just starting on a project. While Django 1.7.x is still supported, Django 1.8.x is a long-term release, meaning it will be supported for at least three years. Good luck!
