Cannot connect to legacy database using django-pyodbc - django-pyodbc

Question

I have installed django-pyodbc and configured my database settings as:
DEV: Windows XP (64bit), Python 3.3, MDAC 2.7
DB: Remote MSSQL 2008
DATABASES = {
'default': {
'ENGINE': 'django_pyodbc',
'HOST': 'my.server.com',
'PORT': '14330',
'USER': 'xxx500',
'PASSWORD': 'passw',
'NAME': 'xxx500',
'OPTIONS': {
'host_is_server': True
},
}
}
I can telnet to the server and I can access the database via 3rd party GUI Aqua Data Studio - so I know there is no firewall issue of login issue
When I try to run this command to introspect the legacy database I get this error...
(myProject) :\Users\...>python manage.py inspectdb
Traceback (most recent call last):

pyodbc.Error: ('08001', '[08001] [Microsoft][ODBC SQL Server Driver][DBNETLIB]SQL Server does not exist or access denied. (17) (SQLDriverConnect)')
What am I missing? Would appreciate some feedback.
Thanks

Answer 1

I made the following changes:
From
DATABASES = {
'default': {
'ENGINE': 'django_pyodbc',
'HOST': 'my.server.com',
'PORT': '14330',
'USER': 'xxx500',
'PASSWORD': 'passw',
'NAME': 'xxx500',
'OPTIONS': {
'host_is_server': True
},
}
}
To
DATABASES = {
'default': {
...
'HOST': 'my.server.com,14330',
...
}
}
and got the utf-8 error that requires commenting out lines 364-367 in the django_pyodbc/base.py file.

I believe that isn't really the solution you'd like to use; modifying the code of django-pyodbc isn't a good idea. That said, be sure you're using the most current fork of django-pyodbc, which can currently be found here:
https://github.com/lionheart/django-pyodbc/
Here's an example DB configuration for settings.py which I've gotten to work on the following platforms (w/FreeTDS / UnixODBC for Linux):
Windows 7
Ubuntu as a VM under Vagrant
Mac OS/X for local development
RHEL 5 + 6
Here's the configuration:
DATABASES = {
'default': {
'ENGINE': 'django_pyodbc',
'NAME': 'db_name',
'USER': 'db_user',
'PASSWORD': 'your_password',
'HOST': 'database.domain.com,1433',
'PORT': '1433',
'OPTIONS': {
'host_is_server': True,
'autocommit': True,
'unicode_results': True,
'extra_params': 'tds_version=8.0'
},
}
}

You need to add the driver to your database back end.
DATABASES = {
'default': {
.......
'OPTIONS': {
.......
'driver' : 'SQL Server',
.......
},
}
}
String. ODBC Driver to use. Default is "SQL Server" on Windows and "FreeTDS" on other platforms.
