Hello,
I have a "dbname" field in my user Profile... and I have one database to
store all default django data, like users, sessions etc.. when I try to get
some ovject in a view, I will get to other database setted in "dbname"
profile... I make this code:
from django.contrib.auth.models import User
from models import UserProfile
import threading
# Object to hold request data
request_cfg = threading.local()
class RouterMiddleware(object):
"""
Set a flag if we are accessing Django admin to
prevent database rerouting for the auth model.
Remove the flag once the request has been processed.
"""
def process_view(self, request, view_func, args, kwargs):
if request.path.startswith('/admin'):
request_cfg.admin = True
def process_response(self, request, response):
if hasattr(request_cfg, 'admin'):
del(request_cfg.admin)
return response
class UserSessionRouter(object):
"""
Redirect database IO for the auth and sessions
models to OldWebsite.com.
"""
def db_for_read(self, model, **hints):
if not hasattr(request_cfg, 'admin'):
if model._meta.app_label == 'auth':
return 'default'
elif model._meta.app_label == 'accounts':
return 'default'
elif model._meta.app_label == 'sessions':
return 'default'
else:
return UserProfile.dbname
return None
def db_for_write(self, model, **hints):
if not hasattr(request_cfg, 'admin'):
if model._meta.app_label == 'auth':
return 'default'
elif model._meta.app_label == 'accounts':
return 'default'
elif model._meta.app_label == 'sessions':
return 'default'
else:
return UserProfile.dbname
return None
But when I try to execute, show me these error:
ImproperlyConfigured at /
settings.DATABASES is improperly configured. Please supply the ENGINE
value. Check settings documentation for more details.
I think the django doesn`t get the correct database to use... and I have
set all database in DATABASE in settings.py
In other words... all django default data use a "default" database, for all
other data using a database setted in "dbname" in UserProfile.
How can I use this?
Best Regards,
F.H.
