Question

I’m trying to connect to an external SQL Server Express database using the django-pyodbc version at: this github link but I keep getting this error when I run manage.py shell to check if I can execute come ORM commands

Traceback (most recent call last):
File "manage.py", line 10, in <module>
  execute_from_command_line(sys.argv)
File "/usr/local/lib/python2.7/site-packages/django/core/management/__init__.py", line   443, in execute_from_command_line

  super(DatabaseOperations, self).__init__()
  TypeError: __init__() takes exactly 2 arguments (1 given)

My settings.py has this:

DATABASES = {
    'default': {
       'ENGINE': 'sql_server.pyodbc',
       'NAME': 'DBName',
       'HOST': '192.168.29.1',
       'USER': 'user',
       'PASSWORD': 'pswd',
       'PORT': 1433,
    }
}

DATABASE_OPTIONS = {
    'driver': '/usr/local/lib/libtdsodbc.so',
    'dsn': 'FreeTDS',
    'extra_params': "TDS_VERSION=8.0"
}

I’m completely at a loss as to what I’m supposed to do, so all ideas are welcome. Essentially what I want is to be able to use a small app I’ve made to interface with the SQL Server database, while being able to use normal DJango ORM commands inplace of pyodbc connection strings (and BTW using pyodbc, I can connect to the SQL Server database without an issue)

Answer 1

it seem to me that you are using the old repo for django-pyodbc at http://code.google.com/p/django-pyodbc/

make sure to cleanly uninstall the old version and then reinstall

pip uninstall sql-server.pyodbc
pip install git+https://github.com/avidal/django-pyodbc.git
