From some forum I came to know that Multiple database support is added in Django at lower level, but the higher level apis are not added yet.
Can anyone please tell
I think you will have to resort to "raw sql" .. kinda thing ..
look here: http://docs.djangoproject.com/en/dev/topics/db/sql/
you need a "connection" to your other database,
if you look at django/db/__init__.py around line 39 (in my version ..)
connection = backend.DatabaseWrapper(**settings.DATABASE_OPTIONS)
try to take it from there ..
P.S. I haven't really tried this or anything .. just trying to point in the general direction of what I think might solve your problem.
